Data Sheet: F-SBAND-Tx/Rx

The F-SBAND series wide band laser

transceivers are designed for enabling a

high linearity optical link for RF over fiber in

the S-BAND up to 5 GHz. The unit can

also be used as a repeater for extending the transmission distance of a 5 Gbps link. The F-SBAND

incorporates a broadband optical transmitter and linear receiver into a compact rack mounted unit.

The F-SBAND can be used for carrying almost any type of RF modulated signals such as RF over

Fiber (RFoG), satellite/IF link, WiMax optical link, microwave over fiber, and mobile signals in fiber.

The unit uses a lithium-niobate external modulator to convert input microwave/RF signals to optical

waveforms from a frequency range of 100 kHz up to 5 GHz. The unit functions as a transparent link,

transporting all satellite modulation formats over a single fiber. The F-SBAND maintains excellent gain

flatness over a wide frequency range due to a very narrow line width DFB laser. Transmission

distances of up to 75 miles are possible using singlemode optical fiber. The F-SBAND link is a cost

effective and high performance solution for S-Band Satellite links.
