DESCRIPTION
The SPS-3380-CXX0 series single mode transceivers is
small form factor pluggable module for bi-directional serial
optical data communications such as SONET OC-3 / SDH
STM-1 and Fast Ethernet. 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. There are eighteen center
wavelengths available from 1270 nm to 1610 nm, with each
step 20 nm. A guaranteed minimum optical link budget of
29 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.
APPLICATIONS
l
ATM Switches and Routers
l
SONET / SDH Switch Infrastructure
l
Fast Ethernet Applications
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.
