1550nm CATV DBC Optical transmitter series increase hot plug-in dual power and optical point. Optical signal of signal source can directly enter into optical interface which not only reduce trouble for connecting optical receiver, but also main signal enters optical point, program made by user entering RF point. Accordingly, program by user is modulated to optical signal which can cater to many demands of user.

LT1500 1550nm optical transmitter is mainly applied in 25 km (digital signal 35Km) distribution network and amplifying. Disadvantage is that it is bad for point to point transmission, Index of it is not good for 1310nm optical transmitter.
