This transceiver features a highly reliable, 850 nm, oxide, vertical-cavity surfaceemitting laser (VCSEL) coupled to an LC optical connector. The transceiver is fully compliant to the 8 G FC, FC-PI-4, and the SFP+ multisource agreement (MSA) specifications, with internal AC coupling on both transmit and receive data signals. The all-metal housing design provides low EMI emissions in demanding 8 G applications and conforms to IPF specifications. An enhanced digital diagnostic feature set allows for real-time monitoring of transceiver performance and system stability, and the serial ID allows for customer and vendor system information to be stored in the transceiver. Transmit disable, loss-of-signal, and transmitter fault functions are also provided. The small size of the transceiver allows for highdensity system designs that, in turn, enable greater total bandwidth.

8.5 G SFP+ 850 NM LIMITING TRANSCEIVER, 8 GIGABIT FIBRE CHANNEL COMPLIANT
2 Section 1 Functional Description
The PLRXPL-VC-SH4-xx-N 8.5 G SFP+ 850 nm optical transceiver is designed to transmit and receive 8B/10B scrambled 8.5 G serial optical data over 50/125 m or 62.5/125 m multimode optical fiber.
Transmitter
The transmitter converts 8B/10B scrambled serial PECL or CML electrical data into serial optical data compliant with the 8 G Fibre Channel standard. Transmit data lines (TD+ and TD-) are internally AC coupled, with 100 differential termination. Transmitter rate select (RS1) pin 9 is assigned to control the SFP+ module transmitter rate. It is connected internally to a 30 k pull-down resistor. A data signal on this pin does not affect the operation of the transmitter. An open collector-compatible transmit disable (Tx_Disable) is provided. This pin is internally terminated with a 10 k resistor to Vcc,T. A logic "1," or no connection, on this pin will disable the laser from transmitting. A logic "0" on this pin provides normal operation. The transmitter has an internal PIN monitor diode that ensures constant optical power output, independent of supply voltage. It is also used to control the laser output power over temperature to ensure reliability at high temperatures. An open collector-compatible transmit fault (Tx_Fault) is provided. The Tx_ Fault signal must be pulled high on the host board for proper operation. A logic "1" output from this pin indicates that a transmitter fault has occurred or that the part is not fully seated and the transmitter is disabled. A logic "0" on this pin indicates normal operation.
Receiver
The receiver converts 8B/10B scrambled serial optical data into serial PECL/CML electrical data. Receive data lines (RD+ and RD-) are internally AC coupled with 100 differential source impedance, and must be terminated with a 100 differential load. Receiver Rate Select (RS0) pin 7 is assigned to control the SFP+ module receiver rate. It is connected internally to a 30 k pull-down resistor. A data signal on this pin has no affect on the operation of the receiver. An open collector compatible loss of signal (LOS) is provided. The LOS must be pulled high on the host board for proper operation. A logic "0" indicates that light has been detected at the input to the receiver (see Optical Characteristics, Loss of Signal Assert/Deassert Time). A logic "1" output indicates that insufficient light has been detected for proper operation.

Notes Power supply filtering components should be placed as close to the Vcc pins of the host connector as possible for optimal performance.
PECL driver and receiver components will require biasing networks. Please consult application notes from suppliers of these components. CML I/O on the PHY are supported. Good impedance matching for the driver and receiver is required. SDA and SCL should be bi-directional open collector connections in order to implement serial ID in JDSU SFP+ transceiver modules. R1/R2 and R3/R4 are normally included in the output and input of the PHY. Please check the application notes for the IC in use.

Recommended application schematic for the 10 G SFP+ optical transceiver
* Transmission lines should be 100 differential traces. Vias and other transmission line discontinuities should be avoided. In order to meet the host TP1 output jitter and TP4 jitter tolerance requirements it is recommended that the PHY has both transmitter pre-emphasis to equalize the transmitter traces and receiver equalization to equalize the receiver traces. With appropriate transmitter pre-emphasis and receiver equalization, up to 8 dB of loss at 5 GHz can be tolerated. ** R5 and R6 are required when an Open Collector driver is used in place of CMOS or TTL drivers. 5 k value is appropriate. *** The value of Rp and Rq depend on the capacitive loading of these lines and the two wire interface clock frequency. See SFF-8431. A value of 10 k is appropriate for 80 pF capacitive loading at 100 kHz clock frequency.

Power supply filtering is recommended for both the transmitter and receiver. Filtering should be placed on the host assembly as close to the Vcc pins as possible for optimal performance. Vcc,R and Vcc,T should have separate filters. Power supply filter component values from Figure 2 are shown in the table below for two different implementations.

Units H F F F
Notes: Option A is recommended for use in applications with space constraints with power supply noise less than 33 mVp-p. Option B is used in the module compliance board in SFF-8431. *If the total series resistance of L1+C6 and L2+C5 exceeds the values of Rx and Ry in the table, then Rx and Ry can be omitted.

Transmitter waveform and dispersion penalty is measured using the methods specified in FC-PI-4 with a 1,0 equalizer and a 9.84-GHz, 3-dB optical bandwidth Gaussian filter for the fiber simulation. 4. Measured with stressed eye pattern as per FC-PI-4. 5. Distances, shown in the "Link Length" table, are calculated for worst-case fiber and transceiver characteristics based on the optical and electrical specifications shown in this document using techniques specified in IEEE 802.3. These distances are consistent with those specified for FC-PI-4. In most cases, longer distances are achievable. 6. The maximum transmitter output power is the lesser of the Class 1 laser eye safety limit and the maximum receiver input power limit. 7. Sensitivity is for informational purposes only.

Digital Diagnostic Monitoring and Serial ID Operation
The PLRXPL-VC-SH4-xx-N optical transceiver is equipped with a two-wire serial EEPROM that is used to store specific information about the type and identification of the transceiver as well as real-time digitized information relating to the transceiver's performance. See the Small Form Factor Committee document number SFF-8472 Revision 10.3, dated December 1, 2007 for memory/address organization of the identification data and digital diagnostic data. The enhanced digital diagnostics feature monitors five key transceiver parameters which are internally calibrated and should be read as absolute values and interpreted as follows:
Transceiver Temperature in degrees Celsius: Internally measured. Represented as
a 16 bit signed two's complement value in increments of 1/256C from -40 to +70C with LSB equal to 1/256C. Accuracy is 3C over the specified operating temperature and voltage range.
Vcc/Supply Voltage in Volts: Internally measured. Represented as a 16-bit unsigned
integer with the voltage defined as the full 16-bit value(0 - 65535) with LSB equal to 100 uV with a measurement range of 0 to +6.55 V. Accuracy is three percent of nominal value over the specified operating temperature and voltage ranges.
TX Bias Current in mA: Represented as a 16-bit unsigned integer with current de-
fined as the full 16-bit value (0 - 65535) with LSB equal to 2 uA with a measurement range of 0 - 131 mA. Accuracy is 10 percent of nominal value over the specified operating temperature and voltage ranges.
TX Output Power in mW: Represented as a 16-bit unsigned integer with the power
defined as the full 16-bit value (0 - 65535) with LSB equal to 0.1 uW. Accuracy is 2 dB over the specified temperature and voltage ranges over the range of -10 dBm to 0 dBm. Data is not valid when transmitter is disabled.
RX Received Optical Power in mW: Represented as average power as a 16-bit un-
signed integer with the power defined as the full 16-bit value (0 - 65535) with LSB equal to 0.1 uW. Accuracy is 3 dB over the specified temperature and voltage ranges over the power range of -14 dBm to 0 dBm.

Reading the data
The information is accessed through the SCL and SDA connector pins of the module. The SFF-8431 Revision 2.2 specification contains all the timing and addressing information required for accessing the data in the EEPROM. The device address used to read the Serial ID data is 1010000X(A0h), and the address to read the diagnostic data is 1010001X(A2h). Any other device addresses will be ignored. MOD_ABS, pin 6 on the transceiver, is connected to Logic 0 (Ground) on the transceiver. SCL, pin 5 on the transceiver, is connected to the SCL pin of the EEPROM. SDA, pin 4 on the transceiver, is connected to the SDA pin of the EEPROM. The EEPROM Write Protect pin is internally tied to ground with no external access, allowing write access to the customer-writable field (bytes 128 - 247 of address 1010001X). Note: address bytes 0 - 127 are not write protected and may cause diagnostic malfunctions if written over.
Decoding the data
The information stored in the EEPROM, including the organization and the digital diagnostic information, is defined in the Small Form Factor Committee document SFF-8472 Revision 10.3, dated December 1, 2007.

4.2 Package and Handling Instructions
This product is not compatible with any aqueous wash process.
Process plug
The PLRXPL-VC-SH4-xx-N optical transceiver is supplied with a process plug. This plug protects the transceiver optics during standard manufacturing processes by preventing contamination from air borne particles. Note: It is recommended that the dust cover remain in the transceiver whenever an optical fiber connector is not inserted.
Recommended cleaning and degreasing chemicals
JDSU recommends the use of methyl, isopropyl and isobutyl alcohols for cleaning. Do not use halogenated hydrocarbons (trichloroethane, ketones such as acetone, chloroform, ethyl acetate, MEK, methylene chloride, methylene dichloride, phenol, N-methylpyrolldone).
Flammability
The housing is made of cast zinc and sheet metal.
4.3 Electrostatic Discharge (ESD)
Handling
Normal ESD precautions are required during the handling of this module. This transceiver is shipped in ESD protective packaging. It should be removed from the packaging and handled only in an ESD protected environment utilizing standard grounded benches, floor mats, and wrist straps.
Test and operation
In most applications, the optical connector will protrude through the system chassis and be subjected to the same ESD environment as the system. Once properly installed in the system, this transceiver should meet and exceed common ESD testing practices and fulfill system ESD requirements. Typical of optical transceivers, this module's receiver contains a highly sensitive optical detector and amplifier which may become temporarily saturated during an ESD strike. This could result in a short burst of bit errors. Such an event would call for the application to reacquire synchronization at the higher layers (serializer/ deserializer chip).

4.4 Eye Safety
The PLRXPL-VC-SH4-xx-N Optical Transceiver is a CLASS 1 LASER PRODUCT as defined by the international standard IEC 60825-1 Second Edition 2007-03 and by U.S.A. regulations for Class 1 products per CDRH 21 CFR 1040.10 and 1040.11. Laser emissions from Class 1 laser products are not considered hazardous when operated according to product specifications. Operating the product with a power supply voltage exceeding 4.0 volts may compromise the reliability of the product, and could result in laser emissions exceeding Class 1 limits.
Caution
Tampering with this laser based product or operating this product outside the limits of this specification may be considered an act of "manufacturing," and will require, under law, recertification of the modified product with the U.S. Food and Drug Administration (21 CFR 1040). The use of optical instruments with this product will increase eye hazard.
