- Cable tv 1550nm Fiber Optic Video Transmitter for Cable Television
16LTxxxx Cable TV optical fiber video transmitter series improved from 08LTxxxx, 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.
16LT50xx series 1550nm optical transmitter is mainly applied 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.
