Should You Buy 3rd Party SFP+?
What does third party optical module mean in reality? It is optical module not supplied and branded by Your network equipment vendor. However, thing is that even You decide to order “original” optical transceivers, You still will get third party. Why so? – Simply, equipment vendors are subcontracting production of these modules to OEM manufacturers, and selling these models with 10 times and more markup. Are they any different from 3rd party optical modules – answer is No. All optical modules are produced according strict standards of MSA (Multisource Agreement) and only difference is that the vendor ID in the EEPROM is reset to the system vendor’s own.

Maximum Operating Frequency and Category Requirements in Cat 3 – 7 Copper Cables
With many variables in play, it can be very trick to know what to do, and what not to do when you work with network cables and design. To work through all the possible permutations, it would help if we could find a way to only change one variable at a time.

Everything you need to know about decibels
Why such terms decibels are used? When you compare cable performance and a manufacturer states that the attenuation (power loss) for a cable operating at 100MHz, with a length of 90 meters is 20dB, it means that the signal strength has dropped by a factor of 100. If you apply an input power of 10 watts, the output will be only be 0.10 watts! That is a 50 percent power loss for every 3dB of attenuation.

What is 100G CFP?

With the continuous development of 5G communication technology, 100G modules are gradually becoming popular. We know that there are many kinds of packages for 100G optical modules. From 2000 to now, the optical module package types have been rapidly developed. Its main package types are: GBIC, SFP, XENPAK, SNAP12, X2, XFP, SFP+, QSFP/QSFP+, CFP, CXP. In the fast-developing network era, some 100G optical modules avoid the risk of being eliminated, and upgraded and revised with the wave of the Internet, such as 100G CFP optical modules.

What is CWDM SFP? Which areas does it mainly apply to?

1. What is the CWDM SFP? The CWDM optical module is an optical module using CWDM technology to implement the connection between the existing network device and the CWDM multiplexer/demultiplexer. When used with a CWDM multiplexer/demultiplexer, CWDM optical modules can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270 nm to 1610 nm) on the same single fiber.

What is AOC and DAC?

AOC is the abbreviation of Active Optical Cables, which is called Active Optical Cables in Chinese. AOC active optical is to encapsulate two optical modules and cable together. Because the medium of transmission in the middle is optical cable, AOC optical module, which contains laser devices, has a higher price for DAC. However, its optical aperture is not exposed, it has high reliability, and its working distance can be customized for a long distance of less than 100 meters.

What is DWDM SFP? What areas does it mainly apply to?

Dense Wavelength Division Multiplexing (DWDM) technology is capable of transmitting data in an optical fiber using bit wavelength parallel transmission or string line transmission using the wavelength of the laser.It is widely used in different fields of communication networks, including long-distance backbone networks, metropolitan area networks (MANs), residential access networks, and local area networks (LANs).The DWDM optical module is the optical module that uses this technology, so the DWDM optical module has high bandwidth and long-distance transmission characteristics.
