1. SR814WB series of 1310nm optical relay station is a two-way optical connector with HFC network engineering experience and equipment development experience accumulate for many years by ourselves only for HFC two-way Broadband Network. This product is designed with full consideration of network topological structure.

The building block system modularized structure is adopted in SR814 Series 

2. Field Optical Work station. It has flexible configuration and convenient debugging, and solves engineering and technical problems of collecting noise with two-way return path network. And it meets the requirements of modern CATV business network security transmission with high reliability of FTTB (Fiber to the Building).

3. SR814W Band SR814WB Optical Workstation are four way independent output models; WR-8604HB and WR-7504HB Optical Workstation are two way independent output models.

4. SR814W BOptical Workstation is our latest flagship product. Advanced optical AGC control circuit adds to the part of optical receiving to ensure the input optical power as low as -9dBm.

 

 

●Two Way Optical Receiver Module is set to automatic switching or manual switching according to the requirement. Switching power supply hot backup module can de switched on line automatically.

●Each down RF channel amplified independently by power double module can output 104 dBμV high lever signal, each road can be enlarged by a new GaAs power double module independently. The output lever and diagonal of each road are adjustable independently. About 100 end user are drove directly when there are no delayed amplification of preamplifier and user amplification.

●Lug-in duplex filters, plug-in fixed equalizer, plug-in fixed attenuator scientific and reasonable test port adopted in SR814WBand SR814WB products make it easier to debug engineering.

●The advanced optical AGC control circuit is used in the part of optical receiving of SR814W product to reduce the optical power to -8dBm; The circuit for RF is improved, so the inserts of attenuators and equalizers are in common use. It makes it is more easy to debug projects and maintain lines. 

●Effective status monitoring circuit in which transponder meeting network management standards called (GB/T 20030-2005 HFC Network Equipment Management System) Standard can de disposed is built in it. So remote network management monitoring for equipment is easily implemented. So it can be suitable for front-end management software of other manufacturers.
