LxLx-ST11xx Low Profile
Optical Transceiver
1x/2x Fiber Channel Applications 3.3V, 850nm VCSEL,
Multimode, Up to 500 Meters
Applications
The LxLx-ST11xx multimode optical fiber transceivers provide low profile, cost
effective solutions for rate agile 1x/2x Fiber Channel multimode optical fiber data
links with a duplex LC connector interface.
These transceivers are fully compliant with the ANSI Fiber Channel standards but
can be used for any other data communications purpose within their operating
parameters.
