Ten common faults and solutions of optical fiber transceivers

Fiber optic transceivers are generally used in the actual network environment where Ethernet cables cannot cover and must use optical fibers to extend the transmission distance. They are usually located at the access layer of broadband metropolitan area networks, and are widely used in various mo... Read More

How to distinguish optical access network OLT, ONU, ODN, ONT

An optical access network is an access network that uses light as a transmission medium, replacing copper wires, and is used to access each home. An optical access network generally consists of three parts: an optical line terminal OLT, an optical network unit ONU, and an optical distribution net... Read More

How to judge whether there is a problem with the fiber optic transceiver?

In general, the luminous power of the optical fiber transceiver or optical module is as follows: multimode is between 10db and -18db; single mode is 20km between -8db and -15db; and single mode is 60km is between -5db and -12db between. But if the luminous power of the fiber optic transceiver app... Read More

Detailed analysis of SFP optical module interface indicators and components

The speed of the optical module SFP+ is: 10G SFP+ optical transceiver is an upgrade of SFP (sometimes called “mini-GBIC”). SFP has been widely used on Gigabit Ethernet and 1G, 2G, and 4G Fibre Channel. In order to adapt to higher data rates, SFP+ has designed enhanced electromagnetic ... Read More

They are all photoelectric conversion functions. What is the difference between optical modules and fiber optic transceivers?

Optical modules and optical fiber transceivers are devices that perform photoelectric conversion. What is the difference between them? Nowadays, long-distance data transmission used in many smart projects basically uses optical fiber transmission. The connection between this requires optical modu... Read More

Can Gigabit SFP optical modules be used on 10 Gigabit SFP + ports?

According to the experiment, the Gigabit SFP optical module can operate in the 10 Gigabit SFP + port, but the 10 Gigabit SFP + optical module cannot operate in the Gigabit SFP port. When a Gigabit SFP optical module is inserted into a 10 Gigabit SFP + port, the speed of this port is 1G, not 10G.... Read More
