FEATURES
DESCRIPTION
l Compliant with Gigabit Interface Converter (GBIC)
Specification Rev. 5.5
The GBS-72120G series optical transceivers meet the
Gigabit Interface Converter (GBIC) specification Rev. 5.5.
It satisfies the optical interface specifications defined in
IEEE 802.3z Drift 5.0 for Gigabit Ethernet. This module is
designed for single mode fiber and operates at a nominal
wavelength of 1550 nm. 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
Avalanche photodetector preamplifier mounted in an
optical header and a limiting post-amplifier IC. A PECL
input / output logic interface is used. TTL RX-LOS output
simplifies interface to external circuitry. A 20-pin SCA-2
host connector is used to connect the converter to the host
system.

A sequence value of 1 indicates that the signal is in the first group to engage during plugging of a module. A sequence value of 2
indicates that the signal is the second and last group. The two guide pins on the connector are electrically connected to the transceiver circuit
ground. These two guide pins make contact with circuit prior to sequence 1 signals.

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.
