NOTE: This product has reached end-of-life status which means that it may no longer be supported and is not orderable from Teleste. Please see the end-of-life page in MyTeleste for more information.

The AC2500 is a dual active output amplifier with 2 x 43 dB operational gain. It offers high output level (111.5 dBμV, 112 channels) and supports 1.2 GHz/204 MHz bandwidth.

The AC2500 amplifier is equipped with the latest technology and delivers incredible performance, flexibility and cost-effectiveness. This amplifier can be used as high gain distribution amplifier, but also as a lower gain trunk amplifier with bridger output. The AC2500 also complies with the DOCSIS 3.1 standard, an important feature designed to meet future service requirements.
