DESCRIPTION
The SPS-4371W-CXX0G series single mode transceiver is
small form factor pluggable module for bi-directional serial
optical data communications such as 8x/4x/2x Fibre
Channel. It is with the SFP 20-pin connector to allow hot
plug capability. Digital diagnostic functions are available
via an I
2
C. This module is designed for single mode fiber
and operates at a nominal wavelength of CWDM
wavelength. There are eight center wavelengths available
from 1470 nm to 1610 nm, with each step 20 nm. A
guaranteed minimum optical link budget of 23 dB is
offered. The transmitter section uses a CWDM multiple
quantum well 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.

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.

Interpretation by Host
Serial module definition
protocol
Module Definition 4 specifies a serial definition protocol. For this definition, upon power up, SDA and SDL appear as no connector
(NC) and MOD-ABS 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.
