Product Number: CAB-GELX-625

This document describes the Catalyst 5000 series mode-conditioning patch cord. When using longwave/long-haul (LX/LH) Gigabit Interface Carriers (GBICs) with 62.5-micron diameter multimode fiber (MMF), you must install a mode-conditioning patch cord (Cisco product no. CAB-GELX-625 or equivalent) between the GBIC and the MMF cable on transmit and receive ends of the link. The patch cord is required for link distances greater than 984 feet (300 meters).

Mode Conditioning Patch Cord Configuration

Note Using the LX/LH GBIC with MMF and no patch cord for very short link distances (tens of meters) is not recommended. The result could be an elevated bit error rate (BER).

Note The patch cord is required to comply with IEEE standards. The IEEE found that link distances could not be met with certain types of fiber-optic cable due to a problem in the center of some fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center, which is accomplished by using the patch cord. At the output of the patch cord, the LX/LH GBIC is compliant with the IEEE 802.3z standard for 1000Base-LX. For a detailed description of this problem, refer to the "Differential Mode Delay" section.

Note Cisco Gigabit Ethernet products have been tested and evaluated to comply with the standards listed in the "Standards Compliance Specifications" section. Equivalent cables should also meet these standards.

Differential Mode Delay

When an unconditioned laser source (LX/LH GBIC) designed for operation on single-mode fiber (SMF) cable is directly coupled to an MMF cable, an effect known as Differential Mode Delay (DMD) might occur. DMD can degrade the modal bandwidth of the fiber-optic cable, which causes a decrease in the link span (the distance between the transmitter and the receiver) that can be reliably supported.

The Gigabit Ethernet specification (IEEE 802.3z) outlines parameters for Ethernet communications at a gigabit-per-second rate. Its initial intent is to offer a higher-speed version of Ethernet for backbone and server connectivity using existing deployed MMF cable. To accomplish this, the specification defines the use of laser-based optical components to propagate data over MMF cable.

Lasers are specified because they function at the baud rates and longer distances required for Gigabit Ethernet. The IEEE 802.3z Gigabit Ethernet Task Force has identified the DMD condition that occurs in certain circumstances with particular combinations of lasers and MMF cable. The resulting characteristics create an additional element of "jitter" which limits the reach of Gigabit Ethernet over MMF cable.

With DMD, a single laser-light pulse excites a few modes equally within an MMF cable. These modes, or light pathways, then follow two or more different paths. These paths may have different lengths and transmission delays as the light travels through the cable. With DMD, a distinct pulse propagating down the cable no longer remains a distinct pulse or, in extreme cases, may become two independent pulses. Strings of pulses tend to interfere with each other making it difficult to recover data in a reliable fashion.

DMD is not experienced in all deployed fibers. It occurs with certain combinations of worst-case fibers and worst-case transceivers. Gigabit Ethernet is the first technology to experience this problem due to its very high baud rate and its long MMF cable lengths. SMF cable and copper cable are not affected by DMD.

Historically, MMF cable has only been tested for use with light-emitting diode (LED) sources. LEDs create a condition within a fiber-optic cable referred to as an overfilled launch condition. The overfilled launch condition describes the way LED transmitters couple light into the fiber-optic cable in a broad spread of modes. Similar to a light bulb radiating light into a dark room, the generated light shines in multiple directions. This light "overfills" the existing cable space and "excites" a large number of modes.

American Tech Supply can save you almost 70% in cost with our mode conditioning patch cords and mode conditionining patch cables that designed to be compatible with the Cisco Catalyst 5000 series mode conditioning patch cords, the Cisco CAB-GELX-625 mode conditioning patch cables & the Nortel AA0018036 mode conditioning patch cables.

The Mode Conditioning Patch Cord, designed to maintain fiber optic cabling polarity in the Telecommunication and Datacom networks.for long haul to Short haul LX GigaBit Systems.
The Connector system combines two, widely accepted, NTT-SC standard connectors in a common duplex housing. This housing, while maintaining polarity of the cable, provides smooth insertion and removal of the connector pairs.

Our Mode Conditioning Patch Cord consists of a cable assembly with an offset singlemode fiber to multimode fiber connection point and duplex SC connectors on each end. This patch cord optimizes the singlemode launch nature of the -LX (1300 nm) transceiver modules used for GigaBit Ethernet that must operate over both singlemode and multimode fibers. A singlemode laser launch into the center of a multimode fiber can generate multiple signals that confuse the receiver at the other end of the fiber. These multiple signals, caused by Differential Model Delay (DMD) effects, limit the system distance lengths for operating GigaBit Ethernet. Our Mode Conditioning Patch Cord eliminates these multiple signals by aligning the singlemode launch away from the center of a multimode fiber.

Mode Conditioning Cables are designed for use in Gigabit Ethernet 1000BASE-LX (1300nm long wavelength) applications. It is fully compliant with IEEE 802.3z application standards. Mode Conditioning Cables, also known as Gigabit launch cables, are needed in applications where new high-speed Gigabit 1000BASE-LX routers and switches are being deployed into existing multimode Plants. The primary function of the Mode Conditioning Cable is to provide an offset launch of the 8.3 µm singlemode core, into the 62.5 or 50 µm multimode core. This offset is required because of a condition known as Differential Mode Delay (DMD). DMD, or multiple overlapping signals, can occur when a singlemode signal is launched into the area of a multimode core that contains a dip in the index of refraction.

Our Mode Conditioning Cables can be ordered in a variety of connector styles, and lengths. The following are examples of available configurations.

Fiber Type		Distance
	62.5 µm			    550 m
	50 µm		            550 m
	9 µm SM			   5000 m

Things to know when using mode conditioning cables to patch an existing multimode cable plant to your Gigabit LX equipment.

1) Mode conditioning cable are normally used in pairs. That means that you will need a MC cable at each end to connect the equipment to the cable plant. So then these cables are usually ordered in even numbers. The usual reason why someone may order one cable is so they may keep it as a spare.

2) 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)
