WE-1550-MINI series 1550nm optical fiber amplifier is an important optical relay transmission equipment in 1550nm optical fiber communication system. It is mainly used in optical networks where FTTH and triple play services are installed in multi-residential units. This product uses high-performance erbium-doped fiber and low-noise pump laser to ensure the stable performance of the whole machine. Compact, lightweight, easy to debug and install, and it is a good choice for building a secondary optical fiber network for CATV.
