DESCRIPTION
The SPS-9140G series single mode transceivers is small
form factor pluggable module for bi-directional serial
optical data communications such as SONET OC-48 / SDH
STM-16, Gigabit Ethernet 1000BASE and Fibre Channel
1x/2x 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
1310 nm. A guaranteed minimum optical link budget of 26
dB is offered which can correspond to a link distance of
over 40 km (assuming worst case fiber loss of 0.45 dB/km).
The transmitter section uses a multiple quantum well
1310 nm 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.

protocol
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 E2PROM protocol of the ATMEL AT24C01A/02/04 family of components.
