Product Description
GDS-6816 series micro-wave Direct Modulated Optical Transmitter, the working broadband is 47~862MHz & 950~6000MHz. By internal frequency overlay, can transmit 4SAT-IF, 4 roads sat TV signals and CATV signal of 47~862MHz with high quality by one fiber.
It can supply high quality of satellite live TV service that come from maximum 4 satellites & CATV service for many users by FTTH, FTTB.
GDS-6816 working wavelength is optional 1310nm or 1550nm. Choose 1550nm working wavelength can use EDFA & EYDFA to realize large area coverage. It is compatible with any FTTx PON technology. Realize multi-way satellite TV, CATV TV and internet integration of three networks.
GDS-6816 can choose 1550nm ITU-T standard wavelength to realize DWDM system application, can transmit 8 SAT-TV, 12 SAT-TV or 16SAT-T by one fiber.
SAT-IF input signal of GDS-6800 can come from 4 different satellites, and also can come from one satellite's 4SAT-IF signal. If adopt one satellite's 4SAT-IF, can adopt Quattro LNB 4SAI-IF output tuner, such as UX-QT.
GDS-6816 adopts high linearity broadband and microwave direct Modulated DFB laser. Excellent laser APC, ATC control, perfect SNMP, RS232 interface. High performance, high flexibility, high reliability and excellent performance price ratio. It is the ideal choice for subscribers.
