GL Hybrid IP Fixed Link System
2 to 23 GHz Modular Hybrid IP Fixed Link System
Modular architecture makes the RF Central GL Fixed Link series the most advanced and flexible microwave fixed link on the market today. Available in all Part 74 and Part 101 microwave bands from 2 to 23 GHz, GL systems can be configured as a traditional indoor system, or a split system with all the RF equipment housed in a separate weatherproof outdoor unit. Over four dozen different modules are available, making it simple to fill any system requirement. The versatile MFR2 mainframe makes it easy to build configurations ranging from a basic simplex link to sophisticated high power, hot standby diversity systems. As new modules are introduced, backward compatible with existing systems is maintained, making the GL link virtually obsolescence proof and ensuring availability of replacement modules for many years to come. Among the modules and features recently added to the GL line, are the PWS/A and PWS/D redundant power supplies, and the excitingly versatile SFP/4 hitless switch and mux card.
A number of our customers requested redundant power supplies for high availability and we heard you. A pair of the new PWS/A and PWS/D fit into a standard MFR/2 mainframe improving reliability. The PWS/A operates on any line voltage from 85 through 264 volts AC. The companion DC supply, the PWS/D runs on 18 through 75 volts DC. A pair of supplies may be mixed and matched within a frame for AC/DC, AC only or DC only operation.
Our SFP/4 combines so many functions into one card it is difficult to list them all. In addition to acting as a four ASI input multiplexer or demultiplexer, this module can serve as a mult-stream 1+1 hitless switch, and an ASI to SMPTE-310 (and reverse) converter. Using the SFP/4 lowers the cost of complicated systems by reducing the card count. Separate hot standby shelfs are a thing of the past. The same modules that make GL Link indoor systems so versatile, work just as well with the our GL Link outdoor unit (ODU) systems. All bands are available, from 2 GHz through 24 GHz, in simplex, duplex or even 1+1 hot standby configurations. ODUs can be pole mounted, or used on a tripod with a dish antenna. For portable operation, COFDM (DVB-T) modulation is built into the UNM/3 modem card. Transmit ODUs are available in power outputs upto +30 dBm.
