The SPS-3131WG 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. Digital diagnostic
functions are available via an I2C. 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.

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.
