Transceiver Module for Gigabit Ethernet
GBIC-1250A5FR
Features
Compliant with Gigabit Interface
Converter (GBIC) Revision 5.4
Compliant with proposed specifications
for IEEE 802.3z/Gigabit Ethernet.
Dual 5V and 3.3V Power Supply
Operation
TTL Logic TX_DISABLE / TX_FAULT /
RX_LOS functions
Class 1 Laser Product Compliant with
the Requirements of IEC 60825-1 and
IEC 60825-2
Hot-Pluggable
RoHS Compliant per Directive
2002/95/EEC
Description
The GBIC-1250A5FR is compliant with GBIC interface
converters specification Rev. 5.4. as well as Gigabit
Ethernet standard as specified in IEEE 802.3.
Delta’s GBIC transceiver family uses a 20-pin connector
to allow hot plug capability. The system designer can
make configuration changes or maintenance simply by
plugging in different type of converters without removing
the power supply from the host system.
Applications
1.25 Gigabit Ethernet
Fiber Channel
Switch to Switch Interface
File server interface
