The SPS-93120G 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-LX 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 1550 nm. A guaranteed minimum optical
link budget of 31 dB is offered which can correspond to a
link distance of over 120 km (assuming worst case fiber loss
of 0.22 dB/km). The transmitter section uses a multiple
quantum well 1550 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.

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

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