When talking about passive products, like patch cord, pigtail, adapter and splitter, will involve UPC and APC description. Some people may be curious. For example, what is LC/UPC - LC/UPC? What is SC/APC - SC/APC? In fact, UPC and APC are two grinding methods for optical fiber bushings. Today we will mainly introduce these two different grinding methods for you to choose the right solution for the...

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 ...

In 40G short-distance optical network transmission, the conventional optical module solution is to use QSFP-40G-SR4 optical module and 12-core MPO multi-mode OM3 fiber patch cord. Although this solution can realize the upgrade of 10G network to 40G network, it uses MPO branch jumpers to connect 10G equipment and 40G equipment are obviously too expensive, so the industry has given a new optica...
