LxK-LT12xx Low Profile Optical Transceiver
Gigabit Ethernet/ 1x Fiber Channel
3.3V, 1310nm FP Laser, Singlemode,
Up to 10.0 Km
Applications
The LxK-LT12xx singlemode optical fiber transceivers provide low profile, cost
effective solutions for Gigabit Ethernet and 1x Fiber Channel optical fiber data
links with a duplex LC connector interface. These transceivers are fully
compliant with the IEEE Gigabit Ethernet and ANSI 1x Fiber Channel standards
but can be used for any other data communications purpose within their
operating parameters.
