1x/2x Fiber Channel Applications
3.3V, 850nm VCSEL, Multimode, Up to 500Meters
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.
