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...

Introduction of 100G DWDM QSFP28 CS Connector PAM4 Transceiver
Jun 09 , 2022
What is PAM4? PAM4 is a technology that uses four different signal levels for signal transmission, and each symbol period represents 2 bits of logical information (0, 1, 2, 3). By transmitting two bits in one symbol slot, PAM4 cuts the signal bandwidth in half. With half the bandwidth, PAM4 can achieve 50Gb/s data transfer in a 25Gb/s electrical tolerance environment. Additionally, PAM4 minimizes ...

How to choose the right fiber patch cord for 10G transceiver?
Aug 05 , 2022
Fiber optic patch cords, also known as fiber patch cord or fiber jumper, are basic and important components used to connect devices and components in fiber optic networks. There are many types of fiber jumpers, such as single-mode fiber jumpers, multi-mode fiber jumpers, 10G OM3 fiber jumpers, 10G OM4 fiber jumpers, MPO fiber cables, etc. This article mainly introduces how to choose a suitable fib...

How to quickly distinguish between optical transceivers and optical transceivers?
Sep 02 , 2022
Both the optical transceiver and the optical fiber transceiver are a transmission tool with optical fiber as the carrier, and both have the function of photoelectric conversion, also called photoelectric converter. Although the two have the same functions, they are essentially different. The following describes the differences between the two. Although optical transceivers and transceivers are bot...

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...

10G SFP+ Optical Module Features Introduction - FIBERWDM
Nov 04 , 2022
In recent years, thanks to the accelerated development of broadband networks, the application of 10G networks has become increasingly widespread. Regarding the 10G SFP+ optical module (the basic transmission equipment of the 10G network), the parameters we need to know are as follows: 1. Center wavelength (nm): There are three main types: 1) 850nm (multimode, low cost but short transmission distan...
