DWDW is short for dense wavelength division multiplexing. It’s a technology for transmitting multiple signals simultaneously at different wavelengths on the same fiber. It can save a lot of optical fiber resources in long distance transmission applications. DWDM can be divided into passive DWDM system and active DWDM system. Passive DWDM system Active devices such as optical fiber amplifiers and d...

Since 1970, the wire and cable industry has used low-smoke, low-halogen materials in many areas. As the improvements of environmental awareness and safety issues, made people realize that wires and cable jackets play a very important role in fires, And have led to the widespread adoption of low-smoke, Zero halogen (LSZH) optical cable. But what is the LSZH? Today we had a training about ...
