Product Description
The 3CGBIC91-A 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 850 nm.
The transmitter section uses a multiple quantum well 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.
