EDFA, CATV insertion

In the case of FTTH networks, it is possible to insert and transmit a 1550nm wavelength CATV signal at the headend, along with data signals of 1490nm and 1310nm wavelengths. Our company offers a complete solution for the 1550nm CATV overlay. Our products include 1550nm optical transmitters and high power optical amplifiers.
