TUZ19 Series Optical Receiver (Button Control)

TUZ19 Optical Receiver is a up-to-date optical receiver with internal microprocessor control. It is designed for FTTx structures of CaTV.

High output level allows to use the device for maintenance of huge amount of subscribers, and to reduce the number of active elements of a network. The slope and level adjusting, multifunctional 3-digit indicator and the multistage protection of all ports provide easy installation by any staff qualification.

The device has a system of reservation by optical inputs. It is equipped with intellectual module for checking and controlling the device via Ethernet. The use of this system is allows the operator not only to increase controllability and reliability of the network, but also to organize some new services which increase the economic efficiency of network.

The housing of receiver is built for 19" rack.
