Compliant with 1X / 2X Fibre Channel FC-PI 13.0
Compliant with Gigabit Interface Converter (GBIC)
Specification Rev. 5.5
CWDM DFB Laser Transmitter
APD High Sensitivity Receiver
Multi-rate Operation for 2.5 / 2.125 / 1.062 / 1.25 Gbps
Duplex SC Connector
28 dB Power Budget At Least
SCA-2 Host Connector
Single +5 V Power Supply
Differential PECL Inputs and Outputs
TTL RX-LOS Output
Hot Pluggable
Class 1 Laser International Safety Standard IEC-60825
Compliant
The GBS-9280-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 1000 BASE for Gigabit Ethernet and 1x/2x Fiber
Channel FC-PI13.0. 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, each step 20 nm. A guaranteed minimum optical
link budget of 28 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.

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.

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 E
2
PROM protocol of the ATMEL AT24C01A/02/04 family of components.
