The SPS-7385-CXX0G series single mode transceivers is
small form factor pluggable module for bi-directional serial
optical data communications such as Gigabit Ethernet
1000BASE-ZX 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 CWDM wavelength. There are
eighteen center wavelengths available from 1270 nm to
1610 nm, with each step 20 nm. A guaranteed minimum
optical link budget of 27 dB is offered The transmitter
section uses a multiple quantum well CWDM DFB 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.

l
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.

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.
