Description

F-KBAND 25 GHz Wide Band K Band Over Fiber Optic Transceiver

The F-KBAND series wide band laser transceivers are designed for enabling a high linearity optical link for RF over fiber in the K-BAND up to 25 GHz. The unit can also be used as a repeater for extending the transmission distance of a 30 Gb/s link. The F-KBAND incorporates a broadband optical transmitter and linear receiver into a compact rack mounted unit. The F-KBAND 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 25 GHz. The F-KBAND maintains excellent gain flatness over a wide frequency range due to a very narrow line width DFB laser. K Band over fiber transmission distances of up to 120 km are possible using singlemode optical fiber.

Features

• Useful Bandwidth up to 20 GHz
• K Band Over Fiber for links up to 120 km
• Highly Linear for Analog Transmission
• Low RIN, Narrow Linewidth DFB Laser
• Broadband LiNbO3 Modulator
• High Power Linear PIN reciever
• Optional RF amplifier to enhance gain
