DESCRIPTION
Hot-Pluggable SFP Footprint LC Optical Transceiver Small Form-Factor Pluggable (SFP) MSA compatible Compliant with SONET OC-3 IR / SDH STM-1 (S-1.1) AC/AC Coupling according to MSA Distance up to 20 km Single +3.3 V Power Supply RoHS Compliant 0 to 70oC Operation: SPS-3120G -40 to 85oC Operation: SPS-3120AG Class 1 Laser International Safety Standard IEC-60825 Compliant
The SPS-3120G series single mode transceivers is small form factor pluggable module for bi-directional serial optical data communications such as SONET OC-3 / SDH STM-1 and Fast Ethernet. It is with the SFP 20-pin connector to allow hot plug capability. This module is designed for single mode fiber and operates at a nominal wavelength of 1310 nm. The transmitter section uses a multiple quantum well laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.
APPLICATIONS
l ATM Switches and Routers l SONET / SDH Switch Infrastructure l Fast Ethernet Applications
LASER SAFETY
This single mode transceiver is a Class 1 laser product. It complies with IEC-60825 and FDA 21 CFR 1040.10 and 1040.11. The transceiver must be operated within the specified temperature and voltage limits. The optical ports of the module shall be terminated with an optical connector or with a dust plug.

Module Definition
Module Definition 4 MOD-DEF2 PIN 4 SDA MOD-DEF1 PIN 5 SCL MOD-DEF0 PIN 6 LV-TTL Low Interpretation by Host Serial module definition protocol
Module Definition 4 specifies a serial definition protocol. For this definition, upon power up, MOD-DEF(1:2) appear as no connector (NC) and MOD-DEF(0) is TTL LOW. When the host system detects this condition, it activates the serial protocol. The protocol uses the 2-wire serial CMOS E 2PROM protocol of the ATMEL AT24C01A/02/04 family of components.
