general features the afct-576 x z family of sfp optical transceivers are high performance, cost effective modules for serial optical data communications applications ranging from 125-155 mbps. they are designed to provide sonet/ sdh compliant connections for 155 mbps at short and intermediate reach links. this includes specifications for the signal coding, optical fiber and connector types, optical and electrical transmitter characteristics, optical and electrical receiver characteristics, jitter characteristics, and compliance testing methodology for the aforementioned. these transceivers are qualified in accordance with gr-468-core. the transmitter section of the transceivers incorporate a 1300nm fabry perot (fp) laser. for each device the receiver section uses an movpe grown planar pin photodetector for low dark current and excellent responsivity. a positive-ecl logic interface simplifies interface to external circuitry. the receiver section contains an ingaas/inp photo detector and a preamplifier mounted in an optical subassembly. this optical subassembly is coupled to a postamplifier/decision circuit on a circuit board. the afct-576xz family of optical transceivers adds digital diagnostic monitoring to standard sfp functionality, enabling fault isolation, components monitoring and failure prediction capabilities. sfp msa compliance the product package is compliant with the sfp msa with the lc connector option. the sfp msa includes specifications for mechanical packaging and performance as well as dc, ac and control signal timing and performance. the power supply is 3.3 v dc. the high speed i/o (hsio) signal interface is a low voltage differential type. it is ac coupled and terminated internally to the module. the internal termination is a 100 ohm differential load. installation the afct-576 x z can be installed in any sff-8074i compliant small form pluggable (sfp) port regardless of host equipment operating status. the module is hot- pluggable, allowing it to be installed while the host system is operating and online. upon insertion, the transceiver housing makes initial contact with the host board sfp cage, mitigating potential damage due to electrostatic discharge (esd). 3 laser driver & safety circuitry 50 ? 50 ? so+ so? amplification & quantization 50 ? 50 ? si+ si? vrefr vrefr tbc ewrap rbc rx_rate

power level provided that the data pattern is valid for nrz code. connection to the transmitter is provided via a lc optical connector. the transmitter has full iec 825 and cdrh class 1 eye safety. tx_disable the transmitter output can be disabled by asserting pin 3, tx_disable. a high signal asserts this function while a low signal allows normal laser operation. the transmitter output can also be disabled and monitored via the 2-wire serial interface. in the event of a transceiver fault, such as the activation of the eye safety circuit, toggling of the tx_disable will reset the transmitter, as depicted in figure 2. figure 2. typical application configuration tx_fault a laser fault or a low v cc condition will activate the transmitter fault signal, tx_fault, and disable the laser. this signal is an open collector output (pull-up required on the host board); a low signal indicates normal laser operation and a high signal indicates a fault. the tx_fault will be latched high when a laser fault occurs and is cleared by toggling the tx_disable input or power cycling the transceiver. the tx_fault is not latched for low v cc . the transmitter fault condition can also be monitored via the two-wire serial interface (address a2, byte 110, bit 2). eye safety circuit under normal operating conditions, the laser power will be maintained below the eye-safety limit. if the eye safety limit is exceeded at any time, a laser fault will occur and the tx_fault output will be activated. 4 figure 3. msa required power supply filter v cc t 0.1 f 0.1 f 10 f 1 h 1 h 0.1 f 10 f 3.3 v sfp module v cc r host board receiver section the receiver section for the afct-576 x z contains an ingaas/inp photo detector and a preamplifier mounted in an optical subassembly. this optical subassembly is coupled to a post amplifier/decision circuit on a circuit board. the design of the optical subassembly provides better than 12 db optical return loss (orl). connection to the receiver is provided via a lc optical connector. rx_los the receiver section contains a loss of signal (rx_los) circuit to indicate when the optical input signal power is insufficient for sonet/sdh compliance. a high signal indicates loss of modulated signal, indicating link failure such as a broken fiber or a failed transmitter. rx_los can be also be monitored via the two-wire serial (address a2, byte 110, bit 1). functional data i/o avagos afct-576 x z transceiver is designed to accept industry standard differential signals. the transceiver provides an ac-coupled, internally terminated data interface. bias resistors and coupling capacitors have been included within the module to reduce the number of components required on the customers board. figure 2 illustrates the recommended interface circuit. digital diagnostic interface and serial identification the afct-576 x z family complies with the sff-8074i specification, which defines the modules serial identification protocol to use the 2-wire serial cmos eeprom protocol of the atmel at24c01a or similar. standard sfp eeprom bytes 0-255 are addressed per sff-8074i at memory address 0xa0 (a0h). as an enhancement to the conventional sfp interface defined in sff-8074i, the afct-5765z is also compliant to sff-8472 (the digital diagnostic interface for sfp). this enhancement adds digital diagnostic monitoring to standard sfp functionality, enabling failure prediction, fault isolation, and component monitoring capabilities. using the 2-wire serial interface, the afct-5765z provides real time access to transceiver internal supply voltage and temperature, transmitter output power, laser bias current and receiver average input power, allowing a host to predict system compliance issues. these five parameters are internally calibrated, per the msa. new digital diagnostic information is accessed per sff-8472 using eeprom bytes 0-255 at memory address 0xa2 (a2h). the digital diagnostic interface also adds the ability to disable the transmitter (tx_disable), monitor for transmitter faults (tx_fault) and monitor for receiver loss of signal (rx_los). contents of the msa-compliant serial id memory are shown in tables 3 to 7. the sff-8074i and sff-8472 specifications are available from the sff committee at http://www.sffcommittee.org. predictive failure identification the diagnostic information allows the host system to identify potential link problems. once identified, a fail- over technique can be used to isolate and replace suspect devices before system uptime is impacted. compliance prediction the real-time diagnostic parameters can be monitored to alert the system when operating limits are exceeded and compliance cannot be ensured. fault isolation the diagnostic information can allow the host to pinpoint the location of a link problem and accelerate system servicing and minimize downtime. component monitoring as part of the host system monitoring, the real time diagnostic information can be combined with system level monitoring to ensure system reliability. application support an evaluation kit and reference designs are available to assist in evaluation of the afct-576 x z sfps. please

joint component recognition for information technology equipment including electrical business equipment ul file # e173874 rohs compliance reference to eu rohs directive 2002/95/ec operating temperature the afct-576 x z family is available in either extended (-10 to +85c) or industrial (-40 to +85c) temperature ranges. power supply noise the afct-576 x z can withstand an injection of psn on the v cc lines of 100 mv ac without a degradation in eye mask margin to 10% on the transmitter and a 1 db sensitivity penalty on the receiver. this occurs when the product is used in conjunction with the msa recommended power supply filter shown in figure 3. regulatory compliance the transceiver regulatory compliance is provided in table 1 as a figure of merit to assist the designer. the overall equipment design will determine the certification level. table 1. regulatory compliance 6 electrostatic discharge (esd) there are two conditions in which immunity to esd damage is important: the first condition is static discharge to the transceiver during handling such as when the transceiver is inserted into the transceiver port. to protect the transceiver, it is important to use normal esd handling precautions including the use of grounded wrist straps, work benches, and floor mats in esd controlled areas. the esd sensitivity of the afct-576 x z is compatible with typical industry production environments. the second condition is static discharge to the exterior of the host equipment chassis after installation. to the extent that the duplex lc optical interface is exposed to the outside of the host equipment chassis, it may be subject to system-level esd requirements. the esd performance of the afct-576 x z exceeds typical industry standards. table 1 documents esd immunity to both of these conditions. electromagnetic interference (emi) most equipment designs using the afct-576 x z sfps are subject to the requirements of the fcc in the united states, cenelec en55022 (cispr 22) in europe and vcci in japan. the metal housing and shielded design of the transceiver minimize emi and provide excellent emi performance. emi immunity the afct-576 x z transceivers have a shielded design to provide excellent immunity to radio frequency electromagnetic fields which may be present in some operating environments. eye safety the afct-576 x z transceivers provide class 1 eye safety by design. avago technologies has tested the transceiver design for regulatory compliance, under normal operating conditions and under a single fault condition. see table 1. flammability the afct-576 x z family of sfps is compliant to ul 94v- 0. customer manufacturing processes this module is pluggable and is not designed for aqueous wash, ir reflow, or wave soldering processes. caution the afct-576 x z contains no user-serviceable parts. tampering with or modifying the performance of the afct-576 x z will result in voided product warranty. it may also result in improper operation of the transceiver circuitry, and possible over-stress of the laser source. device degradation or product failure may result. connection of the afct-576 x z to a non-approved optical source, operating above the recommended absolute maximum conditions may be considered an act of modifying or manufacturing a laser product. the person(s) performing such an act is required by law to re-certify and re-identify the laser product under the provisions of u.s. 21 cf. handling precautions the afct-576 x z can be damaged by current surges or overvoltage. power supply transient precautions should be taken, and normal handling precautions for electrostatic sensitive devices should be taken. optical power budget the worst-case optical power budget (opb) in db for a fiber-optic link is determined by the difference between the minimum transmitter output optical power (dbm avg) and the lowest receiver sensitivity (dbm avg). this opb provides the necessary optical signal range to establish a working fiber-optic link. the opb is allocated for the fiber-optic cable length and the corresponding link penalties. for proper link performance, all penalties that affect the link performance must be accounted for within the link optical power budget. process plug this transceiver is supplied with a process plug for protection of the optical port within the lc connector receptacle. this process plug prevents contamination during handling, shipping and storage. it is made of a high-temperature, molded sealing material that can withstand +85 c. lc sfp cleaning recommendations in the event of contamination of the optical ports, the recommended cleaning process is the use of forced nitrogen. if contamination is thought to have remained, the optical ports can be cleaned using a ntt international cletop stick type (diam. 1.25 mm) and hfe7100 cleaning fluid. 7 notes: 1. tx fault is an open collector/drain output, which should be pulled up with a 4.7k C 10k ? resistor on the host board. pull up voltage between 2.0 v and vcct, r+0.3 v. when high, output indicates a laser fault of some kind. low indicates normal operation. in th e low state, the output will be pulled to < 0.8 v 2. tx disable input is used to shut down the laser output per the state table below with an external 4.7 - 10 k ? pull-up resistor. low (0 - 0.8 v): transmitter on between (0.8 v and 2.0 v): undefined high (2.0 - 3.465 v): transmitter disabled open: transmitter disabled 3. mod-def 0,1,2. these are the module definition pins. they should be pulled up with a 4.7 - 10 k ? resistor on the host board to a supply less than vcct +0.3 v or vccr+0.3 v. mod-def 0 is grounded by the module to indicate that the module is present mod-def 1 is clock line of two wire serial interface for optional serial id mod-def 2 is data line of two wire serial interface for optional serial id 4. los (loss of signal) is an open collector/drain output which should be pulled up externally with a 4.7k - 10 k ? resistor on the host board to a supply < vcct,r+0.3 v. when high, this output indicates the received optical power is below the worst case receiver sensit ivity (as defined by the standard in use). low indicates normal operation. in the low state, the output will be pulled to < 0.8 v. 5. rd-/+: these are the differential receiver outputs. they are ac coupled 100 ? differential lines which should be terminated with 100 ? differential at the user serdes. the ac coupling is done inside the module and is thus not required on the host board. the volt age swing on these lines will be between 250 and 2000 mv differential (160 - 1000 mv single ended) when properly terminated. 6. vccr and vcct are the receiver and transmitter power supplies. they are defined as 3.135 - 3.465 v at the sfp connector pin. the maximum supply current is 250 ma and the associated inrush current will be no more than 30 ma above steady state after 500 nano seconds. 7. td-/+: these are the differential transmitter inputs. they are ac coupled differential lines with 100 ? differential termination inside the module. the ac coupling is done inside the module and is thus not required on the host board. the inputs will accept differenti al swings of 500 - 2400 mv (250 - 1200 mv single ended), though it is recommended that values between 500 and 1200 mv differential (250 - 60 0 mv single ended) be used for best emi performance. table 2. pin description pin name function/description msa notes 1 veet transmitter ground 2 tx fault transmitter fault indication note 1 3 tx disable transmitter disable - module
