Mode conditioning cable are designed for Gigabit Ethernet multimode applications at 1300nm wavelength; the application standard is IEEE 802.3z. All mode conditioning fiber optic patch cords are made with duplex cable; with a single mode to multimode offset fiber connection part in one of the two legs, as you can see the real cable pictures on our PDF catalogue.

Here is the reason we need to use the mode conditioning patch cord : the Gigabit Ethernet application standard requires the use of fiber optic light to achieve the specified data transmitting rates. Usually people use long wave transceiver modules for Gigabit Ethernet, these modules have to operate both single mode and multi mode fibers. And as we know, multimode fiber manufacturing techniques create index of refraction anomalies along the centerline of the multi mode fiber core. When a highly concentrated single mode fiber optic light is sent into the center of a multimode fiberglass, the modes that propagate through the index of refraction anomalies spread out in time causing modal dispersion, this effect is called differential mode delay. Differential mode delay results in reduced bandwidth over distance. By allowing the single mode laser launch to be offset away from the center of the multi mode fiber the mode conditioning patch cord reduces the effect of such differential mode delay.

From the above descriptions we learn how to use such mode conditioning cables: when we use such mode conditioning fiber optic patch cords, we need to connect the yellow leg which is the color of single mode to connect the transmit side of the equipment (single mode Gigabit transceiver) while we connect the orange leg which is the color of multimode to the receive side.

Mode conditioning fiber optic patch cord are used typically when you want to run Gigabit Ethernet (LX) over some multi mode fiber optic plant. Huihong Fiber Inc mode conditioning fiber optic cable are compliant with IEEE 802.3Z standard. In some cases such as for long wave laser modules used in Gigabit Ethernet ,the modules need to operate for both single mode and multimode fibers ,the mode conditioning fiber optic cables will fit for such situations ,they can reduce the different mode delay when light transmitted from single mode fiber cables into multi mode fiber cables. Huihong Fiber Inc supply mode conditioning cables in various combinations of SC, ST, MT-RJ and LC with very short lead time.
