GBIC-1250 Long Distance Series
RoHS Compliant 1250Mbps Gigabit Interface Converters (GBIC)
Transceiver Module for Gigabit Ethernet
Features
Compliant with Gigabit Interface
Converter (GBIC) Revision 5.4
Compliant with proposed specifications
for IEEE 802.3z/Gigabit Ethernet
Dual 5/3.3V Power Supply
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/EC
Description
The GBIC-1250xxxx families are 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
