DESCRIPTION
The GBS-92120FG 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-LX for Gigabit Ethernet and 1x / 2x Fibre Channel
FC-PI 13.0. This module is designed for single-mode fiber and
operates at a nominal wavelength of 1550 nm.
A guaranteed
minimum optical link budget of 30 dB is offered which can
correspond to a link distance of over 120 km (assuming
worst case fiber loss of 0.21 dB/km). 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 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.
