GBIC-1250A5FR
RoHS Compliant 1250Mbps Gigabit Interface Converters (GBIC)
Transceiver Module for Gigabit Ethernet
GBIC-1250A5FR
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.
Features
z Compliant with Gigabit Interface
Converter (GBIC) Revision 5.4
z Compliant with proposed specifications
for IEEE 802.3z/Gigabit Ethernet.
z Dual 5V and 3.3V Power Supply
Operation
z TTL Logic TX_DISABLE / TX_FAULT /
RX_LOS functions
z Class 1 Laser Product Compliant with
the Requirements of IEC 60825-1 and
IEC 60825-2
z Hot-Pluggable
z RoHS Compliant per Directive
2002/95/EEC
Applications
z 1.25 Gigabit Ethernet
z Fiber Channel
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.
