The SPS-73120-CXX0G series single mode transceivers is
small form factor pluggable module for bi-directional serial
optical data communications such as Gigabit Ethernet 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 32 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
Avalanche photodetector preamplifier mounted in an
optical header and a limiting post-amplifier IC.

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 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
2
PROM protocol of the ATMEL AT24C01A/02/04 family of components.
