FC equip to SC Multimode OM3/OM4 50/125 Mode Conditioning Patch Cable

Fiber-Mart manufactures and supplies standard and custom length 50/125, 62.5/125 and OEM equivalent mode conditioning fiber optic patch cords for 1000BASE-LX/LH Gigabit Ethernet (1300nm long wavelength) applications installed into existing multimode cable plants. These specialized cords help avoid Differential Mode Delay (DMD) effects that can occur when long wave transceiver modules operate at both single-mode and multimode wavelengths. And they are available with FC,ST, SC, LC and MT-RJ connectors.

How the Mode Conditioning Cable Works
The need for this conditioning fiber optic patch cord is due to the single-mode launch nature of the -LX or long-wave (1300nm) transceiver modules used for Gigabit Ethernet. Launching a single-mode laser into the center of a multimode fiber can cause multiple signals to be generated that confuse the receiver at the other end of the fiber. In that case, a mode conditioning patch cord eliminates these multiple signals by allowing the single-mode launch to be offset away from the center of a multimode fiber. This offset point creates a launch that is similar to typical multimode LED launches. (see diagram below)



Notes:

• If some customers remain reluctant to deploy MCP cables, and for customers using OM3 or OM4 cables, please measure the power level before plugging the fiber into the adjacent receiver. When the received power is measured above -3dBm (in 1000BASE-LX links), a 5-dB attenuator for 1300nm should be used and plugged at the transmitter source of the optical module on each side of the link. Actually, OM3/OM4 MCP can also work in this event. While whether all multimode fiber types require mode conditioning, you can contact the manufacturer of your installed cable for the answer.
• Mode conditioning patch cords can only convert single-mode to multimode. If you want to convert multimode to single-mode, then a media converter will be required.
• Another alternative for short reaches within the same location is to use a single-mode patch cable. There will be no saturation over single-mode fiber.


How to Install the Mode Conditioning Cable
If your gigabit LX switch is equipped with SC or LC connectors, please be sure to connect the yellow leg (Singlemode) of the cable to the transmit side, and the orange leg (multimode) to the receive side of the equipment. It is imperative that this configuration be maintained on both ends. The swap of transmit and receive can only be done at the cable plant side. (see diagram below)

Things to Know When Using Mode Conditioning Cables

• Mode conditioning patch cords are usually used in pairs. Which means that you will need a mode conditioning patch cord at each end to connect the equipment to the cable plant.
• Generally, Mode Conditioning patch cords are required for link distances greater than 984 feet (300 meters).
