Description
2600 CATV amplifier with AGC two-way output bi-directional sub-trunk amplifier, suitable for the signal amplification of coaxial sub-trunk in HFC system. It has the feature of high gain, high output level, and excellent CTB, CSO. Its return loss is 16 dB and the frequency of its four bi-directional filters is optional. The default configuration is two-way output, and can become three-way output by inserting distributor or fixed coupler.
