Модель: Foxcom_GL7220



Summary
Foxcom Gold GL 7220 RF Optical DownLink L-Band [950-2220MHz], 4dB Optical Budget Foxcom's Sat-Light/Gold L-Band Interfacility Link offers a high performance, cost effective alternative to conventional coaxial-cabled systems. The Gold L-Band IFL covers the range of 950 to 2200MHz. The Gold Series L-Band link is designed for a wide range of satellite uplinking facilities whereby high input power levels are required. Foxcom’s high dynamic range DFB laser delivers exceptional signal quality for the most demanding applications. The new Gold series is compatible with first generation Sat-Light 7000 Series platform. The Gold Series support L-Band, 70/140MHz IF, Wide Band (10-2200 MHz), 10MHz Reference, Redundancy, M & C, SNMP, Ethernet, and Serial Data Communication. The link consists of an optical transmitter, which receives the RF signal from an LNB or LNA, and an optical receiver that connects to the indoor receive equipment. All satellite modulation schemes are accommodated –digital or analog. Inherently low phase is achieved by direct modulation of the laser diode.
