FEATURES
DESCRIPTION
l 18-Wavelength CWDM GBIC Transceivers: 1270 nm to
1610 nm, each step 20 nm
The GBS-7250-CXX0G 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. There are
eighteen center wavelengths available from 1270 nm to
1610 nm, each step 20 nm. A guaranteed minimum optical
link budget of 19 dB is offered. The transmission distance
is depended on the wavelength and loss of fiber. 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. 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.
