1550nm External Optical Transmitter

Item No.: VT-15XX
1550nm externally modulated optical transmitter with the best performance and the highest index. It is the first choice for long-distance transmission and large area covered local networks. It is applied to:  the optical modulation and optical insertion of large and medium-sized 1550nm optical transmission system; the upgrading and expansion of WDM and its related networks. It is the core equipment of 1550nm network transmission system to for triple-play and FTTx.
