What is Mode Conditioning Patch Cables?

Definition of Mode Conditioning Patch Cables
Mode Conditioning Patch Cables (MCP) is a duplex multi mode patch cord that has a small length of single-mode fiber cable at the start of the transmission leg including a single mode to multi-mode offset fiber connection part. Mode Conditioning Patch Cables are assembled with connectors using 62.5/125um or 50/125um fiber. The calibrated offset reduces phenomena called differential mode dispersion, or DMD, which can cause the transmitting laser pulse to spread out and merge into neighboring pulses creating bit errors in the transmission signal.

DMD can cause a multimode fiber with a laser source to have a lower bandwidth than the same fiber with a LED source. The way to control DMD is to find a way of steering the injected laser light around the “dip”. That is the function and purpose of a Mode Conditioning Patchcord.
Use of Mode Conditioning Patch Cables
Mode conditioners are built in the form of a simple duplex patch cable, so they can easily be installed in a system without the need for additional components or hardware. Their length can range from one meter and up to support virtually any network topography. When you need to connect the Gigabit-LX or a 10-Gigabit LRM transceiver optics with existing multimode fibers, you need this MCP cables installed at both ends of the network link. The commonly used Mode Conditioning Patch Cables (MCP) cables including LC to LC, LC to SC, LC to ST, LC to FC, SC to SC, ST to ST connectors with OM1/OM2/OM3 fiber cables.

012019-10With 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.

012019-101. 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.

012019-10AOC 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.
