CATV T0X optical transmitter with automatic gain control 234811 from Televes
Televes T0X optical transmitter
The Televes optical transmitter T0X 234811 generates an optical signal, in the 1550nm window, modulated by the input RF signal (47 – 1100MHz).
The optical output power is 10dBm.
This transmitter incorporates automatic gain control (CAG).
In addition, it is stable in temperature thanks to its laser temperature control circuit.
The 234811 transmitter is suitable for RFoG solutions and also as an RF Overlay transmitter in GPON networks.

Year Warranty *Special Order! NCNR – Check Lead Time* This unit can be used as a cascade element
since it has 13 outputs to connect to other switches and increase the number
of users. This range of products has been designed with the ECO system: as
the number of users decreases, the power consumption of the system will
decrease as well. Gain in the FI band can be selected individually for each
group of 8 users to provide a balanced output. -

Order! NCNR – Check Lead Time* Compact
multiswitch equipped with 17 inputs (one terrestrial and 16 for four
satellites, each with its four polarities) and 8 user outputs. Thanks to its great compactness and its
optimized electronic design, it presents very low through and tap losses.
This allows to reduce the number of amplifiers needed in the cascade and to
obtain a better balanced signal in the users, even in large collective
installations. Can be used as a
terminal (star topology) or as a cascade by using a simple switch. In
addition, it incorporates a second switch that actives the TForce technology,
which automatically adjusts the terrestrial signal and keep it constant
despite variations in the reception. RED compliant Main Features: High shielding (A class) thanks to its
manufacture in Zamak Versatile: selector switch to shift between cascade and
terminal modes Low consumption under normal conditions. In addition, ECO mode
reduces consumption as the number of connected users decreases Wide 12-18V
power supply range, making it compatible with most existing systems Current
