Available in 150m 492 length 50 µm or 62 5 µm multimode and 150m 492 500m 1 640 and 1000m 3 281 9 µm singlemode cable options. A launch fiber will help to overcome the blind spot or dead zone of an otdr brought about by high launch power or faults near the launch end of the fiber.

Otdr configuration the optical time domain reflectometer otdr is an instrument that uses the inherent backscattering properties of an optical fiber to. The komshine otdr launch cable is designed to aid in the testing of fiber optic cable when using an otdr to help minimize the effects of the otdr s launch pulse on measurement uncertainty. Select fiber ring otdr launch cable for your otdr. A sm launch cable should be 500 1000 m long to ensure the test signals are singlemode.

Noyes fiber rings from afl are a necessity when testing with an otdr. A 150 m launch tail cord will work for fiber links of 2 km or less typically found in enterprise networks. Launch fibers place a necessary length of fiber between the otdr and the actual fiber being measured providing both the time and distance required for the otdr to effectively measure the characteristics of the fiber being tested. Afl fiber optic otdr launch cables are compatible with all otdr brands and are fully taa compliant.

Multimode fiber will change mode power distribution with length. Otdr launch cable leadequipment calibration. Teleweaver offers otdr launch cable with 150m 300m 500m 1000m or customized length as per customers requirements. Is an otdr launch cord cable the same thing as a pulse suppressor or launch fiber.

Both a launch and receive cable are needed to measure complete link loss of a fiber with an otdr. In summary an otdr launch fiber provides both the time and distance required for the otdr to effectively look at and measure the characteristics of the entire length of fiber being tested. It allows the otdr to settle down properly and gives you a chance to see the condition of the initial connector on the cable plant. It should be long at least 500 to 6000 meters to be safe and the connectors on it should be the best possible.

Otdr fiber launch cables application illustration. Dead zones can be overcome by connecting a long launch cable to the otdr. The length of the launch cable may affect sm or multimode measurements. You always want to see the beginning of the cable plant and you cannot do it without a launch cable.
