Harmonic has added a set of CWDM-based 1310 nm forward path transmitters to its family of PWRLink transmitters. The new transmitters increase available bandwidth by combining multiple wavelengths on existing fiber. The approach is designed to be a less costly alternative to running new fiber closer to the home.
Harmonic's CWDM technology can provide two or more wavelengths in the 1310 nm frequency band that can be combined onto a single fiber for forward transmission and then separated at the node to be demultiplexed and processed by different receivers.
Harmonic called the CWDM technology highly cost-effective, scalable and easy-to-implement. Sunil Frida, director of HFC solutions for Harmonic, said the approach “saves on fiber usage and also provides more flexibility by enabling different wavelengths to carry different types of traffic or content according to the operator's specific requirements."
