Analysis of common problems in fiber testing

The following sections provide detailed analysis of common problems in fiber testing. (1) Why does the fiber test pass but the packet is still lost during network operation? In the choice of standard, many users will make some obvious mistakes, such as paying little attention to whether the teste... Read More

The picture illustrates what is fiber? Classification of optical fibers?

1.optical fiber core structure 1) Core: high refractive index, used to transmit light; 2) Cladding: low refractive index, forming a total reflection condition with the core; 3) Protective layer: protects the optical fiber. 2.Single-mode and multi-mode Only one mode of light can be transmitted....

What are the fiber connection methods

Optical fiber is an indispensable element in today’s network age, but do you really understand optical fiber? What are the fiber connection methods? What is the difference between optical cable and optical fiber? Is it possible for fiber to completely replace copper cables from outside What... Read More

How to connect fiber optic transceiver? What is the difference between single fiber / dual fiber transceivers?

When weak current projects encounter long-distance transmission, fiber optics are often used. Because the transmission distance of optical fiber is very long, in general, the transmission distance of single-mode fiber is more than 10 kilometers, and the transmission distance of multi-mode fiber c...

How is Combo PON compatible with GPON and XGPON?

With the implementation of the “Broadband China” and “Speed-up and fee-reduction” strategies, China ’s fixed broadband network capabilities have been continuously improved; user broadband has changed from 10M and below to 50M / 100M / 200M, and has evolved towards Gigabit;... Read More

Evolution history of 2G to 5G optical communication modules

Development of wireless optical communication modules: 5G networks, 25G / 100G optical modules are the trend In the beginning of 2000, 2G and 2.5G networks were under construction, and the base station connection began to cut from copper cables to optical cables. At first, 1.25G SFP optical modul... Read More
