FEATURES
DESCRIPTION
l Compliant with Gigabit Interface Converter (GBIC)
The GBS-7250G series optical transceivers meet the
Specification Rev. 5.5
l Compliant with IEEE-802.3z / D5.0 Gigabit Ethernet
Gigabit Interface Converter (GBIC) specification Rev. 5.5.
It satisfies the optical interface specifications defined in
1000BASE-XD
l 50 km using Single-mode Optic Cable
l 1550 nm DFB Transmitter
l 19 dB Power Budget at Least
l Hot Pluggable Module with Duplex SC Connector
l SCA-2 Host Connector
l Single +5 V Power Supply
l RoHS Compliant
l Differential PECL Inputs and Outputs
l TTL RX-LOS Output
l Class 1 Laser International Safety Standard IEC-60825
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
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
Compliant
system.
APPLICATIONS
l Switch to Switch Interface
l High Speed Interface for File Servers
l Bus Extension Application
l Data Storage
