What is Dense Wavelength Division Multiplexing
Mar 08 , 2022
The so-called dense is relative to the interval between two adjacent wavelengths. In the past, the wavelength interval of the wavelength division multiplexing system was several tens of nanometers. Now the wavelength interval is only 02 to 1.2 nm. The spectrum allocation is shown in Figure 2-1. DWDM technology is actually a specific form of wavelength division multiplexing. Generally, the waveleng...

What is a CWDM/DWDM multiplexer/demultiplexer?
May 20 , 2022
As we all know, WDM (Wavelength Division Multiplexing) is a technology that uses multiple lasers to send multiple lasers of different wavelengths on a single fiber at the same time. It can realize two-way communication on one fiber and increase network capacity. In a WDM system, a multiplexer is generally used at the transmitting end to multiplex several optical signals into a bundle of optical ca...

Optical Modules VS Transponders: What's the Difference?
Jul 08 , 2022
The optical transceiver module is a network interconnection device that realizes photoelectric signal conversion, and the repeater is a network interconnection device that realizes the regeneration, amplification and wavelength conversion of optical signals. conversion, but the functions and applications of the two are very different, and they are not interchangeable. Optical Module VS Transponder...

Why 400G QSFP-DD is more popular than 400G OSFP and 400G CFP8
Oct 14 , 2022
At present, the main products of 400G transceivers are QSFP-DD, OSFP and CFP8. This article introduces: Why 400G QSFP-DD is more popular than 400G OSFP and 400G CFP8 1: QSFP-DD provides maximum port density. This makes QSFP-DD more attractive than OSFP form factor modules and larger CFP8 modules. 2: The power consumption (the maximum power that the module can dissipate without damaging the interna...

How to solve when the optical module fails?
Nov 11 , 2022
During the use of the optical transceiver module, various problems will inevitably occur. The following summarizes the main reasons and solutions in the event of failure. Matters needing attention before use 1. Do not connect optical modules with different wavelengths. Due to the different transmission loss and dispersion in the fiber, the transmission distance corresponding to different wavelengt...
