INTRODUCTION
The SL2150 fiber optic links connect antennae with control rooms, network operation centers
or broadcast head ends. SL2150 links offer more than an alternative to coaxial cabling in
teleport earth stations. They have been designed to provide very low carrier-to-noise ratio
and extremely linear performance. This means a cost effective technically superior
installation for the satellite signal user. Multidyne systems have been engineered to give
industry-leading performance when compared with any other fiber optic link. Only SL2150
links have ultra wide dynamic range so that automatic gain control is not required to cope
with changing signal intensity caused by meteorological conditions. A range of options to suit
a variety of installations is offered, such as 75Ω or 50Ω impedance with either BNC or F
connectors. The standard link utilizes a high performance DFB laser, but for less demanding
short haul applications, a lower cost FP laser option is available. For installations where the
number of cross site fiber connections is limited the complete ITU range of CWDM
transmitter wavelengths is offered allowing up to 8 channels to be carried on one fiber.
Optical connector options include ST, LC, FC, or LC APC.
