The SPS-4310RW-CXX0G s series is a 1 to 6.25 Gb/s
single-mode transceiver module for serial optical
communication applications for a radio base station system.
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 eighteen center wavelengths available from 1270
nm to 1610 nm, with each step 20 nm. A guaranteed
minimum optical link budget of 11 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.
