Mini Line LR 91 An optical receiver for FttB / FttH
Category : Optical Network Terminations
The LR 91 is an extremely low-noise optical receiver. Because of the high output level it is particularly well suited for direct house distribution. The measurement point can be displayed through the LED and the DC, in the range of -8 to +1 dBm. Its compact design requires a minimum amount of space, and the built-in measuring socket allows control of the signals.
