Data Sheet: F-RF-Tx

The F-RF-TX transmitter is used to

transmit RF cable TV signals (45-

870MHz) over a fiber optic cable. By

converting the RF band to an optical

signal the transmission distance can be

increased to over 120 km. The transmitter uses external modulation technology with a direct current

laser. This results in no laser chirp, low dispersion distortion, a large extinction ratio, and high speed

signal transfer. The F-RF-TX features an easy to read front panel LCD screen that displays relative

operating status and fault information. The unit implements a high linearity DFB laser, and features

built in pre-distortion adjustment circuity. The F-RF-TX direct modulated optical transmitter can be

used in FTTx (10Km) of second-grade service area (Sub-HE) and can also be used in WDM narrow-

band multiplexing and IP/QAM. Our RF transmitter units feature dual power supplies for added fault

protection. All operating parameters of the F-RF-TX series transmitters are designed for high reliability

and suitable for even the most high end applications.
