Chronicle of the development of optical fiber communication systems

With the continuous development of optical communication technology, optical fiber communication has experienced five generations since its appearance. It has undergone optimization and upgrade of OM1, OM2, OM3, OM4 and OM5 fiber, and has made continuous breakthroughs in transmission capacity and... Read More

Classification of fiber optic and fiber optic transceivers

From the late 1980s, fiber-optic communications gradually shifted from short-wavelength to long-wavelength, from multimode fiber to single-mode fiber. At present, single-mode fiber is widely used in the national cable trunk network and the provincial trunk line network. Multimode fiber is only li... Read More

Do fiber optic transceivers have to be used in pairs?

Do fiber optic transceivers have to be used in pairs?Is there a split in the fiber transceiver?Or just a pair of fiber optic transceivers can be used to form a pair? If the fiber transceivers must be used in pairs, is it necessarily the same brand and model? Or can you use any combination of bran... Read More

Classification and testing of 400G optical module

Optical module is the key hardware equipment to realize optical network interconnection in data center. With the increase of port number and density, the cost of optical module will account for nearly half of the cost of optical network in data center.At present,  100G interconnection technology ...

What are the advantages of OM5 fiber jumper compared to OM3/OM4?

“OM” in optical communication refers to “Optical Multi-mode”. Optical mode, which is a standard for multimode fiber to indicate fiber grade. Currently, TIA and IEC defined fiber patch cord standards are OM1, OM2, OM3, OM4, and OM5. First of all, what is multimode and single mode? Sing... Read More

Three minutes to understand fiber optic communications

Optical fiber communication is the main transmission means of modern communication networks. Its development history is only one or two decades. It has experienced three generations: short-wavelength multimode fiber, long-wavelength multimode fiber and long-wavelength single-mode fiber.The use of... Read More
