Foxcom's Sat-Light/Gold S-Band Optical Link offers a high performance, cost effective alternative to conventional coaxial-cabled systems. Sat-Light/Gold S-Band IFL covers the range of 2000 to 4000MHz. The Gold Series S-Band link is designed for a wide range of satellite and wireless applications. Foxcom’s high dynamic range DFB laser delivers exceptional signal quality for the most demanding of requirements.

The new Sat-Light 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 a high dynamic range optical transmitter, which converts incoming

RF signals into optics, and an optical receiver that re-converts the optical signal back into RF. All satellite modulation schemes are accommodated –digital or analog. Inherently low phase is achieved by direct modulation of the laser diode.
