* Frequency range 47~2700MHz, 47~862M for cable TV, 950~2700MHz for micro-wave signal such as radio frequency, satellite and MMDS.
* Mixed input and separate input for the user’s choice. Mix model means the cable TV and radio Frequency share one input, separate means the two input separately.
* Output from 3dBm~10dBm, and single or dual out for the user’s choice.
* Adopt original external modulator laser and modulator
* Good parameter in CTB, CTN and C/N
* Adjustable SBS in 13,16, 19，step 0.1dB.
* AGC and MGC control.
* With hot-plug dual power supply
* Automatically shell temperature control.
* RS232 and RJ 45 for local and remote management.
