Professional provider of high-end integrated DWDM solutions for big data transmission

The world is accelerating the construction progress of 5G network, and the N×25Gbit/s WDM technology applied to 5G prequel has become the preferred solution for the prequel network. Considering cost, power consumption, performance, reliability and other factors, it is mainly divided into four kinds of multiplexing technologies: coarse, medium, fine and dense. A few days ago,   HTF   has achieved a large number of   CWDM , DWDM wave separator shipment, performance fully meet the operator standard requirements. Domestic 5G phase III construction will start soon, and overseas 5G construction will speed up.   HTF   will bring competitive wave separator series products to help 5G construction to land. The semi-active scheme focuses more on the functional characteristics such as maintenance and management, and the added OAM function of semi-active equipment drives the demand growth of TAP-PD.  HTF  has been deeply engaged in this kind of products for nearly...

  WDM : Wavelength division multiplexing is a technology that simultaneously transmits two or more optical  signals of different wavelengths in the same optical fiber. CWDM  : Coarse wavelength division multiplexing, generally covering wavelengths of 1270~1610nm , DFB lasers will be used , the channel spacing is relatively wide, usually 20nm , the main application, a total of 18 waves, relatively low cost, mainly used in Aggregation layer and access layer. So it can be used for our fronthaul, CWDM6 application. DWDM : dense wavelength division multiplexing, the wavelength interval will be relatively small, 0.2nm~1.2nm . The main working wavelengths are 1525nm~1565nm in C -band and 1570nm~1610nm in L- band . It focuses on long-distance transmission and is applied to the transmission network. Therefore, the low-loss C -band is selected, and EML lasers are usually used. To ensure the wavelength, they are all equipped with TEC , so the cost of the device will be relatively h...
