“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...

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...

After a period of intense and orderly installation, commissioning and equipment operation training,the SMT production line of Shenzhen HDV photoelectron technology Co., LTD was officially put into production on August 15,2019.Prior to this, through complete SMT production of the board, the equip...

With the rapid development of the Internet, the transmission distance of the twisted pair and the influence of electromagnetic interference are limited, which restricts the development of the network. Therefore, the optical transceiver has emerged.The use of fiber optic transceivers replaces the ...

After the optical module is installed, testing its performance is an essential step.When the optical components in the entire network system are supplied by the same vendor, if the network system can work normally, there is no need to separately test the sub-components of the system.However, most...

5G, big data, artificial intelligence and other technologies have higher requirements for data processing and network bandwidth.Data centers need to continuously improve network bandwidth to meet.Therefore, there is an urgent need to improve network bandwidth in data centers these days, especiall...
