Dense wavelength division multiplexing (DWDM) is a wavelength division multiplexing (WDM) technology that expands the transmission capacity of existing optical fiber networks. Save a lot of fiber resources in transmission applications. There are two main types of DWDM systems at present: passive DWDM systems and active DWDM systems. Passive DWDM System Active components such as… Continue reading Passive DWDM System vs Active DWDM System

1. The Type-A solution includes a pair of simplex CWDM MUX DEMUX modules and a pair of 1CH simplex CWDM OADM modules over a single fiber. In this situation, the Tx and Rx of the dual fiber CWDM transceivers use different wavelengths. 2. The Type-B solution includes a pair of simplex CWDM MUX DEMUX modules and… Continue reading How 3 typical CWDM solutions for different simplex BiDi transmission systems?

As the application of optical modules becomes more and more widespread, the speed, packaging, power consumption and functions of optical modules are also developing in the direction of high speed, small size, low power and multi-function. Today we are going to talk about the DDM function in the optical module. What is DDM? DDM (Digital… Continue reading DDM in optical module

Optical ports of transceivers also require proper cleaning to ensure the fiber transmission performance. Look at the picture, you will find why we need clean optical transceiver module? For no apparent reason, optical signals are lost during the operation of a device,  So need clean the receptacle or the optical connector. This will eliminate contamination… Continue reading Why optical module signals are lost during the operation of a device?

Seen from their industry names, QSFP56, QSFP28 and QSFP+ are very similar in that they share the same QSFP form factor as their postfix shows, and they have the same size as each other. However, their data center and connectivity capabilities are different. Below is a table listing the basic parameters of QSFP56, QSFP28, and… Continue reading QSFP56 vs QSFP28 vs QSFP+
