Description
SC Fiber Loopback, Single Mode and Multimode
SC Loopbacks are used to provide test engineers with an effecient way to test the transmission capability and receiver sensitivity of optical network equipment. The loopback module type is enclosed in a rugged housing, featureing a compact design, long thumb release. The loopback cable type is protected by a standard, flexible, flame-retardant and highly durable PVC jacket, molded A and B channel markings, and a custom designed strain relief boot.
SC fiber optic loopbacks are compliant with fast Ethernet, fiber channel, ATM and Gigabit Ethernet.
