GENERAL FEATURES
The OTLT linear fiber optic transmitter and the OTLR linear fiber optic receiver form the basic L-Band Fiber Distribu-
tion System. The wide bandwidth of 500MHz to 3,000MHz allows for a wide variety of communications applications
including L-Band satellite antenna remoting, trunking radio, telemetry tracking and time and frequency reference distri-
bution. The extended frequency range to 3.0GHz allows this to accommodate additional transponders including Euro-
pean satellite communications applications. The enhanced bandwidth also facilitates stacked LNB applications to
accommodate additional transponders containing enhanced DBS services (HDTV, local channels, etc.) over single-
mode fiber for DBS distribution.
These stand-alone versions are designed for mounting in outdoor enclosures or in other small spaces. For powering,
the stand-alone units both the transmitter and receiver can be powered via the wire leads or on the center of the coax
connector.
