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 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...

Related working principle and applications of Tunable DWDM transceiver
Sep 07 , 2021
DWDM is a laser technology used to increase bandwidth on existing fiber optic backbone networks. More precisely, the technology is to multiplex the tight spectral spacing of a single fiber carrier in a specified optical fiber in order to utilize the achievable transmission performance (for example, to achieve the minimum degree of dispersion or attenuation). In this way, With a given information t...

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...

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 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...

Why is the 25G SFP28 LWDM transceiver used in the 5G future network?
Aug 06 , 2021
At present, 25G optical transceivers have been widely used in 5G future networks. In order to save fiber resources, a 25G WDM module is used in the 5G front drive. However, 25G WDM transceivers are much more expensive than other 25G optical modules. The 25G SFP28 LWDM transceiver can realize multi-channel signal transmission on a single fiber, and the cost is lower than that of the 25G WDM transce...

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...
