�Model�� CL-870-T�
CL-870-T, 1310 or 1550nm Direct Modulated AGC Optical Transmitter

Cable TV Band RF over Fibre Transmitter

The CL-870-T 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 120Km. 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 CL-870-T 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 CL-870-T 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. All operating parameters of the CL-870-T series transmitters are designed for high reliability and suitable for even the most high end applications.
