Description

Optical Distribution Station DS optical distribution station is a high performance, four individual outputs node. With high output levels and performance to **2MHz, it provides an ideal platform for support of the evolving technologies and services in advanced HFC networks. Designed with full flexibility, DS offers a variety of configurations which are ideal for analog and digital transmission, telephony and data services. Utilizing extensive modular design, DS can meet any advanced network requirements. DS offers a complete scalable solution for opto-electronic deployment in any broadband system. Configured in sturdy, weatherproof rugged die-casting housing, suitable for strand or pedestal mounting, it operates over a wide temperature range and accepts cable powering *0~*0V high-efficiency switch mode power supply. Internal RF connections are made with *5Ohm type ***** test connections are standard type F. Use of the latest technology gives DS high signal quality with increased system reliability and reduced maintenance. The unit has four identical bidirectional coaxial ports. The interstage equalizer and 4 other equalizers for each port provide a solution to different network structure. DS offers a wide variety of pass band options. Diplex filters are available at *5/*7, *2/*4 and *5/*7MHz, allowing operation in virtually any cable system worldwide. All of the bi-directional ports are capable of passing power into or out of the unit. Separate attenuator and equalizer configure each of the ports. Careful design of the receiver circuit allows for a variety of channel loading of *0~**0 NTSC analog channels, *9 or more PAL analog channels, or a combination of analog and digital signals. The forward system receiver modules are compatible with either ***0nm or ***0nm signals. Each receiver utilizes a receiving module to assure optimum carrier-to-noise performance. There are also LEDs indicates the level of optical input and alarms status.
