How to choose fiber optic transceiver modules?
Aug 11 , 2022
As a local area network connector device, the main task of the optical transceiver is how to seamlessly connect the data between the two parties. Therefore, it is necessary to consider its compatibility with the surrounding environment and the stability of its own products, so various factors need to be considered when choosing. 1. See if it can support full-duplex and half-duplex, because some ch...

WDM Transceiver Form Factor – SFP, SFP+ or QSFP28?
Aug 25 , 2022
You need to consider the physical interface of the switch or network device you are using. Multiple industry standards ensure network equipment compatibility and a range is available including SFP, SFP+, SFP28, QSFP28 or XFP. Examples of data transfer rates and ranges for CWDM and DWDM in different available form factors are given below. Note that both XFP and SFP+ can transmit signals up to 10 Gb...

How tunable dwdm works
Sep 09 , 2022
For tunable transceivers we might ask why it only works in DWDM systems. This is because the frequency spacing in CWDM systems is too wide compared to the narrow band gaps of DWDM systems. Dense Wavelength Division Multiplexing (DWDM) was originally Refers to the ability (and cost) to multiplex optical signals in the 1550 nm band to take advantage of Erbium-Doped Fiber Amplifiers (EDFAs), which ar...

What is the difference between CWDM technology and DWDM technology?
Sep 16 , 2022
In WDM technology, there are CWDM coarse wavelength division multiplexing technology and DWDM dense wavelength division multiplexing technology. Literally, these two technologies have different degrees of density in a band, but there are still many practical technologies and applications. difference. ①The wavelength interval is different The CWDM carrier channel spacing is wider and each band is 2...

Differences between industrial switches and fiber optic transceivers
Sep 21 , 2022
The difference between an industrial switch and a fiber optic transceiver is that the fiber optic transceiver is actually a point-to-point industrial switch, which is just a photoelectric conversion device. It is only a method used to extend the transmission interval because the transmission interval is too long; An industrial switch is an Ethernet connection device for data exchange within the ne...

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...

Advantages of BiDi Transceivers
Oct 20 , 2022
1. Save fiber resources and costs Since BiDi optics can realize the transmission and reception of optical signals through a single fiber, the biggest benefit of BiDi transceivers is that they save fiber resources and are cost-effective high-quality short-distance solutions, which are suitable for areas without additional fiber resources. of great value. The reduction in fiber usage saves the cost ...

Application of WDM (passive wavelength division multiplexer) in 5G fronthaul
Oct 25 , 2022
Passive wavelength division multiplexer (WDM) designed to address fiber resources for long-haul transmission between distributed units (DUs) and active antenna units (AAUs) in Centralized Radio Access Network (C-RAN) 5G fronthaul architectures In addition, passive WDM can save fiber resources. In passive WDM, color optical modules are directly deployed on AAUs and DUs, and multiple AAUs can share ...
