Cable television is a system of delivering television programming to paying subscribers via radio frequency (RF) signals transmitted through coaxial cables or, in the 2010s, light pulses through fiber-optic cables. This contrasts with broadcast television, in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation.

1310nm CATV Laser Transmitter
This laser transmitter is important equipment to built CATV HFC network. It is mainly used for long distance optical fiber transmission of television signal, digital TV signal telephone voice signal and data. High performance DFB laser
The type of transmitter can used for retransmit of optical signal. It can also be used as a same 1310 RF optical transmitter. In this type of transmitter low power Optical Signal is used to convert into its equivalent RF.
1550nm External Transmitter is mainly used for long distance optical feeder transmission of television image signal. Digital TV signal and data signal. Double Microwave Sources SBS controlling technology researched
1550nm Direct Mode Transmitter is mainly used in overlay insertion system adopted 1550nm Direct laser only used in Dense Wavelength Division Multiplexing system(DWDM). Its output Optical Wavelength is long as standard ITV wavelength.
Mini Optical Transmitter is very small in size but very accu-rate in performance. Very high Technical calculation is incor-porated with it. It produces 10dbm Optical power or 11dbm optical power with very accurate RF output at receiver end.
