FEATURES
DESCRIPTION
l 18-Wavelength CWDM GBIC Transceivers: 1270 nm to
1610 nm, each step 20 nm
The GBS-72120G-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 32 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.
