What is Mode Conditioning Patch Cable and Why Need It?
Fiber Optic Mode Conditioning Patch Cable(MCP) is one duplex multimode fiber patch cord, which have one short length of single mode fiber at the start of the transmission end.
Gigabit Ethernet (GbE) requires a laser light source instead of an LED source to power the network, due to the lasers faster rise and fall times, the pulses of light injected into the fiber are more tightly packed together thus greater bandwidth.
Without the use of mode conditioning patch cord, multiple signals are generated when a single-mode laser launch into the center of a multimode fiber. Multiple signals can be generated that overlap each other and make it difficult for the receiver to interpret. This condition is known as Differential Modal Delay (DMD).
Mode conditioning patchcord matches a single mode fiber core with the corresponding multimode fiber core. Utilizing a calibrated offsetting between the single-mode and multimode fiber, it eliminate the so called DMD effect.
Fiber optic mode conditioning cable provide a convenient, reliable method of connecting 1000BASE-LX/LH, 10GBASE-LX4 and 10GBASE-LRM based Gigabit Ethernet Transceiver modules to cable plants deploying multimode fibers, fully compliant with IEEE 802.3 standards.
MCP is manufactured in a standard form of a duplex fiber patch cord. And a mode conditioning cable can be installed in a fiber link without the need for additional components or hardware.
The mode-conditioning patch cord is installed between the transceiver and the patch panel. To install the patch cord, follow these steps:
