BSRF AFR-250S
The AFR-250S is a optical/RF converter. Used with the AFB-250 it lets you take advantage of propagation of light on monomode fiber.
Tha AFR-250S can be used in several situations, it can be used on a sound cart, in a bag or integrated in a watertight case. If you need, up of 4 units can be fixed on a 19'' rack mount (conctact us for more information).
The attenuator setting will help experts to fine tune sensitivity/noise in multi antenna situation. Leds light up to indicate too strong RF signal or too much optical loss.
There are two ways of powering the AFR-250S, the classical one is through a DC push pull connector, the other one is through the DC feed voltage coming from the receiver or active antenna splitter/combiner. The AS-62 and AS-122 can be used to power it.
The AFR-250S enclosure is made of aluminium, build to last and recyclable.
