Description
Overview
GAOTek multi output port transmitter is a high output power type of CATV optical transmitter. The height of the transmitter is IU, it can be mounted on the 19 in frame conveniently. It is a combination of 1550 nm internal modulation optical transmitter and 1550 nm EDFA, output power ranges from 13 dBm to 24 dBm and one, two or more outputs for the user’s choice. It adopts low-noise original DFB laser as the source of 1550 nm internal modulation optical transmitter.
Features
