Detailed Product Description

HT8500BC(CATV wavelength)
HT8500BU(ITU wavelength adjustable)

Utility-type External Modulation Optic Transmitter(47~862MHz, CNR1≥52dB, SBS: 13, 16dBm adjustable)

RFTV is a unidirectional analogue and digital video broadcast, it adopts high efficiency modulated mode for RF carrier wave, its economical efficiency, flexibility and bandwidth validity is beyond comparison of IPTV. Adopting EPON or P2P access mode to realize triple-play, FTTx. RFTV broadcasting network in 1550nm optical wavelength still plays an important role, 1550nm Externally Modulated optical transmitter is the core equipment in this system.

Main application

Used in middle and small CATV center head end, solve the transmission of trunk and distributive network with high quality and low cost.

Used in second-grade service area of substation, provide the value added service, such as RFTV,IPTV,VOD and so on, with excellent cost performance, high quality and high reliable. Avoid adopting 1550nm direction modulated optical transmitter transmit bandwidth, transmit distance limitation and system CSO deterioration which cause by laser chirp.
