Hot-Pluggable SFP Footprint LC Optical Transceiver Small Form-Factor Pluggable (SFP) MSA compatible Compliant with IEEE 802.3z 1000BASE Compliant with Fibre Channel 1x SM-LC-L FC-PI AC/AC Coupling according to MSA Distance up to 20 km Single +3.3 V Power Supply RoHS Compliant 0 to 70oC Operation: SPS-7120G -10 to 85oC Operation: SPS-7120BG -40 to 85oC Operation: SPS-7120AG Class 1 Laser International Safety Standard IEC-60825 Compliant
The SPS-7120G series single mode transceivers is small form factor pluggable module for bi-directional serial optical data communications such as Gigabit Ethernet 1000BASE and Fibre Channel 1x SM-LC-L FC-PI. 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.

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.
