CATV 1550nm Externally Modulated Optical Fiber Transmitter
(47~862MHz, CNR1≥ 53dB, SBS: 13, 16, 18dBm adj. )
Product description
1550nm externally modulated optical fiber transmitter is the core equipment in this system. RFTV is a unidirectional analogue and digital video broadcast. It adopts high efficiency modulation mode for RF carrier wave and its economy, 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 transmitter wavelength still plays an important role.
Product feature
1. High performance: Externally modulated technology for optical Fiber transmitter, no laser chirp, low dispersion distortion, high extinction ratio, with excellent characteristic within 40~862MHz in-band.
2. Narrow bandwidth (Typ. =1MHz), lower noise, DFB continuous wave laser.
3. ITU standard wavelength adjustable, the user can adjust and set the laser wavelength on the front-panel with ± 0.05nm stepping in the range of ± 200GHz (± 1.6nm), used in the network upgrading and expansion of WDM system.
4. AGC/MGC mode is optional at spot.
5. Perfect RS232 communication interface.
6. SNMP network management function optional.
7.1+1 backup power supply optional.
8. Casing temperature auto-control.
9. Excellent P/P ratio.
Main application
1. Used in middle and small CATV center head end
2. Used in second-grade service area of sub-station. Provide second-grade users with high quality and high reliability value added service such as RFTV, IPTV, VOD and so on.
