How to quickly distinguish between optical transceiver and optical transceiver?
Jul 22 , 2021
Optical transceivers and optical fiber transceivers are both transmission tools that use optical fibers as carriers, and both have the function of photoelectric conversion, also called photoelectric converters. Although the two have the same functions, they are still different in nature, so many people who don’t know may be confused about what is an optical transceiver and what is a transceiver. A...

DWDM Multiplexer And Demultiplexer is A Wise Choice
Jul 23 , 2021
The emergence of big data requires efficient and capable data transmission speed. In order to solve the paradox of increasing bandwidth and spending less, multiplexers/demultiplexers are the best choice. This technology can transmit very large data traffic in the telecommunications network. This is a good way to deal with the bandwidth explosion from the network. Wavelength division multiplexing W...

What is the difference between a cable and an optical cable?
Aug 12 , 2021
The cable is used to transmit electrical signals, and the inside is a copper core wire, usually a rope-like cable that is twisted by several or several groups of wires [each group of at least two]. The core wire diameter is divided into 0.32mm, 0.4mm and 0.5mm. The larger the diameter, the stronger the communication ability; and the number of core wires is divided into: 5 pairs, 10 pairs, 20 pairs...

What is the difference between CWDM technology and DWDM technology?
Sep 01 , 2021
There are CWDM coarse wavelength division multiplexing technology and DWDM dense wavelength division multiplexing technology in WDM technology. The two technologies have been specifically mentioned in the previous article. From a literal point of view, these two technologies are different in the density of a band. , But the actual technology and application are still very different. ① Different wa...

Different kinds of passive optical tap
Oct 13 , 2021
A network-connected passive optical TAP usually has at least three ports: A port, B port and monitoring port. Let's take a look at the differences between them. Passive network taps in optical fiber-based networks Passive network taps can be used on fiber optic networks of all speeds-just choose a rated copy and send traffic at the same rate as your network (1 Gigabit, 10 Gigabit; 40 Gigabit, 100 ...

What is a DWDM optical module?
Oct 22 , 2021
DWDM optical module belongs to a kind of WDM optical module. It uses DWDM technology to multiplex multiple optical signals into one optical fiber to transmit data using different wavelengths. This operation does not need to consume any power. These optical modules are designed for high-capacity and long-distance transmission, with a rate of up to 10Gbps and a working distance of up to 120km. Class...

Analysis of the advantages and disadvantages of passive DWDM Mux
Nov 05 , 2021
Information network technology developers continue to strive to improve the throughput and quality of network data lines, while reducing the cost per bit (CPB) of the network. One of these technologies is dense wavelength division multiplexing (DWDM). DWDM is a method of creating multiple virtual fiber lines, which effectively increases the capacity of physical fiber lines. Wavelength division mul...
