What is the difference between a full-duplex optical module and a half-duplex optical module?

With the rapid development of network communication technology, the requirements for urban informatization construction are getting higher and higher. Optical fiber has the advantages of low loss rate, high transmission rate, insensitive to bending, long transmission distance, and strong anti-interference. More and more users choose use. The importance of the optical module as the connection device between the optical fiber jumper and the switch is self-evident, and the most common optical module is the non-duplex optical module. So, what is a duplex optical module? And how do duplex optical modules and fiber jumpers match layout?

What is a duplex optical module?

Optical fiber patch cords can be divided into simplex and duplex according to the working mode of the interface. Generally, the optical module matched with the simplex fiber patch cord is commonly called the simplex optical module; the optical module matched with the duplex fiber patch cord is commonly called Duplex optical module.

What are full-duplex optical modules and half-duplex optical modules?

Duplex optical modules can be divided into full-duplex optical modules and half-duplex optical modules. Full-duplex optical modules are generally called ordinary optical modules. They can be transmitted in both directions at the same time when they are transmitted by two different transmission lines. Can receive data while sending data. The half-duplex optical module is also called BIDI optical module, which refers to both transmission and reception by a transmission line, but only one direction of data transmission at a time, that is, data is received after the data is sent.

Wiring solutions for duplex optical modules

Data center cabling is the nervous system of network transmission. Through the collocation of optical modules, optical fiber copper cables, switches, cabinets, cable management and other products, the normal transmission of data is ensured. Due to the difference in port type and distance between devices, different products need to be flexibly matched.

40G and 10G interconnection network scene, through MTP-4LC duplex branch jumper, one end connects 40G optical module, the other end connects 410G duplex optical module to achieve the effect of normal network operation.

In the network scenario where the Gigabit optical module is interconnected, the two ends are connected to the Gigabit LC duplex optical module through the LC-LC duplex single-mode fiber jumper to achieve the effect of normal network operation. With the rapid development of data centers nowadays, duplex optical modules are widely used, but the connection of duplex optical modules and the functions to be realized have a great relationship with product layout design.
