Our experts will answer any technical questionTUZ 88 is a series of state-of-the-art optical receivers with microprocessor control, designed for operation in FTTB optical networks.
High output level allows using receivers for servicing a greater number of subscribers, and thus reducing the number of active components in the distribution networks.
Direct setting of level and slope parameters, informative indicator and multistage ports protection will make installation possible by personnel of any level of competence. A highly intellectual Ethernet-based monitoring and control module can be installed at your option. The use of such system allows both increasing the network controllability and transparency, and introducing new services, thus enhancing its economic efficiency.
STU-00 Indication and Control Module
STU-01.5 Transponder and Control Module
The module is designed for local and remote monitoring and control over optical receiver parameters. It also allows controlling receiver reservation, AGC mode and level settings, and slope and level parameters.
The module also performs check of input optical power, supply voltage, temperature inside the housing and status of alarm circuits. The collected data is transferred to the control computer via Ethernet.
