Specific steps for SFP transceiver replacement
Jul 30 , 2021
When an optical fiber link fails, the SFP transceiver in the port used to provide the link may need to be replaced. To replace a failed SFP transceiver with a new transceiver received from the CRU or FRU warehouse, use this procedure. Before the start Although many components are hot-swappable components, they can only be used when your system is inactive (no I/O operations). If the system is powe...

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...

Common reasons why SFP transceivers stop working
Aug 18 , 2021
The small form factor (SFP) transceiver is a compact, hot-swappable module for computing in telecommunications and data communication applications. Due to people's needs, the increase in high-speed data transmission has led to a rapid increase in the demand for SFP modules. The application in the market is also getting wider and wider. SFP transceivers can be used in a variety of applications. How...

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...

What are the performance indicators that affect the WDM wavelength division multiplexer?
Sep 26 , 2021
What are the performance indicators that affect the WDM wavelength division multiplexer? 1. Working band The working band of WDM devices, such as 1550 wavelength, is divided into three bands: S band (short wavelength band 1460～1528nm), C band (conventional band 1530～1565nm), L band (long wavelength band 1565～1625nm). 2. Number of channels and channel spacing The number of channels refers to the nu...

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 ...

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...
