Optical Fiber Patch Cord Multimode to Singlemode  Mode Conditioning Fiber Patch Lead

Mode- Conditioning Patchcords

Description

Mode Conditioning Patchcord is designed for use in Gigabit Ethernet 1000BASE-LX solution.

This duplex patch cord consists of connectors on each end with a single-mode fiber offset to a multimode fiber connection in one of the two ends. It is compliant with the IEEE 802.3z application standard. This patch cord is necessary to allow -LX 1300 nm transceiver modules to be used for Gigabit Ethernet.
Mode Conditioning Patch Cords are between 2 metres and 5 metres in length. It is not practical to have these patchcords in lengths outside these limits.
A mode conditioning patch cord eliminates multiple signals .

Features

• Converts Singelemode LC GBIC to Multimode SC Patch Panel

• 62.5/125 and 8.3/125

• Run 1000Base-LX Gigabit Ethernet over MMF by offsetting signal loss

• Use LC GBIC Singlemode Transceivers on Multimode Fiber Backbones with SC patch bays

• Offsets the Singlemode Laser launch from the center of a Multimode fiber

• Lifetime limited warranty

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)

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)
