DESCRIPTION
The GBB-7820G series single-mode optical transceivers
meet the Gigabit Interface Converter (GBIC) specification
Rev. 5.5. It satisfies the optical interface specifications
defined in IEEE 802.3ah 1000BASE BX by using 1310 nm
transmitter and 1490 nm receiver. 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 1490 nm
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.
