Summary:
This unit is used in relay transmitting after receiving 1310nm/1550nm signal or in forward retransmitting to extend distance of transmitting signal. And this unit adopts modularization design and has reverse function to configure flexibly according to practical project requirements, with two independent RF outputs for local use when transmitting downward signal.
Features:
1).This unit, with optical receiving and forward transmitting function, is good solution to transmit and relay signal without equipments room
2).With two outputs, more than 104dBuv, which can drive around 200 users directly
3).Adding reverse function to meet the configuring request of HFC bidirectional transmission system
4).With DFB laser at the forward optical transmitting module
5).Laser status indicator to send alarm when unusual power break
6).Laser input RF level test; over-high RF level protection
7).Reverse transmitting module laser FP or DFB available for users to choose
8).High-performance and high-reliability switch power supply, with large designed allowance when overvoltage and overheat
9).Waterproof aluminum-cast shell, with good heat loss.
