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...

The reason why wdm network is so popular
Aug 17 , 2022
With the adjustment and improvement of various traffic routes, the distance between everyone is also farther and farther. Voice, video and data networks are becoming more complex as the demand for more bandwidth and faster transfer rates increases. To meet these demands, network administrators rely more on fiber optics. Many suppliers, corporate companies and government entities are turning to fib...

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 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...

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...
