Description

Satellite Fiber Links equipment Foxopto&#**9;s L-band Fiber links FX-LFs offer a high performance, cost effective alternative to conventional coaxial-cabled systems. Foxopto�s L-band Fiber FX-LFs cover the range of **0�***0 MHz. They are used for the transmission over single-mode fiber optic cable of block downconverted C, extended C, X or Ku band signals. The transmission of L-band Satellite signals as well as communication radar transmission and reception are also made possible using Foxopto&#**9;s L-band range of products.

Because of the remote location of some dish farms, L-Band transport equipment must be able to withstand wide environmental conditions. Signal quality is usually assured through some means of gain control, either manual, automatic, or fixed. Many Teleports also incorporate some form of remote monitoring and control using Simple Network Management Protocol (SNMP) tools to remotely monitor such parameters as RF signal level, optical output power (in fiber optic networks), gain settings, device status, and other parameters. Quite often, a redundant optical and/or RF system and antenna diversity are utilized to protect the satellite distribution system from the effects of weather-fade and sun-fade outages. Figure 1 illustrates an optically redundant system and Figure 2 illustrates an RF redundant signal. 2.>Applications for an L-Band Satellite Transport System Antenna remoting and relocation commonly appear at radio and television stations, although headend relocation to a installation also ***** signals above 2 GHz are converted *****
