GL Digital Fixed Link System
2 to 23 GHz Fixed Links
Modular architecture makes the RF Central GL series the most advanced and flexible microwave fixed link on the market today. Available in all microwave bands from 2 to 23 GHz, GL systems can be configured as a split indoor/outdoor or as a completely indoor system. From duplex systems built in a single rack unit mainframe to the most sophisticated hot standby diversity systems, a wide and growing variety of modules makes it simple to fill any system requirement. All new modules are backward compatible with existing systems, making the GL link virtually obsolescence proof.
Take the latest RF Central GL series modem card, the UNM/3. Like the UNM/2 modem it replaced, the UNM/3 is a full duplex card. But in addition to offering all the features of the older model, the UNM/3 offers two separate ASI inputs and outputs, as well as a transparent Ethernet port. Yet, it can be easily added to any existing GL Link to expand capabilities or for replacement purposes.
In addition to the highly versatile UNM/3, encoder and decoder modules are available that make it a simple matter to add a remote camera to a studio transmitter link, or to connect a remote news bureau. In fact, the system offers well over four dozen different modules that make it simple to design a system that exactly fills user needs. With our four port multiplexer and demultiplexer cards, a single radio can carry up to six ASI streams and Ethernet data.
