DESCRIPTION
The SPS-4381RW-DXXG 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 100GHz ITU Grid, C
Band DWDM wavelength. A guaranteed minimum optical
link budget of 23 dB is offered. The transmitter section
consists
of
a
temperature-stabilized
DWDM
electrical-modulated laser (EML), driver and signal
conditioner. The receiver section uses an integrated InGaAs
detector preamplifier (IDP) mounted in an optical header
and a limiting post-amplifier IC.
6.144 Gbps / 100GHz DWDM / 80 km / LC SFP+ SINGLE-MODE TRANSCEIVER

APPLICATIONS
l
Radio Base Station
l
OBSAI rates 6.144 Gb/s, 3.072 Gb/s, and 1.563 Gb/s
l
CPRI rates 4.9152 Gb/s, 2.4576 Gb/s, and 1.2288 Gb/s
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, SDA and SDL appear as no connector

serial CMOS E

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