Also, free sample is also available if necessary. Welcome to buy our high quality products or wholesale our customized fc fiber optic loopback cables in stock with our factory. MeFiberOptic.Com is one of the largest and best fc fiber optic loopback cables manufacturers and suppliers with rich experience. Range ≤ 0.2 dB ( – 40 to +80 degree centigrade) specifications FC Fiber Optic Loopback CablesĮxchange ability ≤ 0.2 (500 cycle passed) the common fiber optic loopbacks types are: SC fiber optic loopback ,FC fiber optic loopback, LC fiber optic loopback,ST fiber optic loopbacks,MT-RJ fiber optic loopback. we also offer custom assemblies for fiber optic loopback. Com Co.,Ltd makes the fiber optic loopbacks strictly according to industry standard, each of the cable is functionally tested before shipping, and we offer custom assemblies for fiber optic loopbacks such as custom connector configurations and special polished.įC Fiber optic loopbacks are with compact design, and they are compliant with fast ethernet, fiber channel, ATM and Gigabit ethernet. Similar as FC fiber optic patch cords, FC fiber loopback can be with various jacket types and cable diameters, and they can be with different terminations and length. Sending a loopback test to network equipment, one at a time, is a technique for isolating a problem. For the testing applications, the loopback signal is used for diagnosing a problem. For other transceiver modules that are not mentioned in this post, we can also know how to choose a suitable loopback for it by getting details about its interface type, physical contact and cable type.Ĭomprehensive performance testing makes sure the cable work more secure and data transmission more reliable and stable in your network.FC Fiber Loopback testers is designed to provide a media of return patch for a fiber optic signal typically it is used for fiber optic testing applications or network restorations. This post discusses specific fiber loopback choices for some most commonly used fiber optic transceivers. Table 4: Loopback choices for CFP transceiversĢ4 Fibers MTP/UPC Multimode Fiber Loopback Table 3: Loopback choices for 100G QSFP28 transceivers Shop fiber optic adapters, media converters and loopback testers, products are TAA compliant and ready to ship nationwide. Provides a looped signal to test the transmit and receiving functions. LC/UPC Duplex Multimode/Single-mode Fiber Loopback Duplex LC 50/125 Multimode Fiber Optic Loopback (TAA Compliant) 26988. Table 2: Loopback choices for 40G QSFP+ transceiversĨ/12 Fibers MTP/UPC Multimode Fiber LoopbackĨ/12 Fibers MTP/APC Single-mode Fiber Loopback Table 1: Loopback choices for 10G SFP+ transceivers The selection guide for some mostly used transceiver modules is summarized in the following tables. Which to Choose for a Specific Transceiver?Ĭonsidering the common features of the transceiver and the loopback, we should think about the connector type, polish type, and cable type when selecting a loopback for the transceiver. Mini SC loopback is suit for 0.9mm cable and 0.25mm fiber. They are compliant with fast Ethernet, fiber channel, ATM and Gigabit Ethernet. The best practice is to send a loopback test to network equipment, one at a time for isolating the problem.įiber optic loopbacks are designed in a compact footprint. When used in testing applications, loopback signals are used for diagnosing problems. Typically it is used for fiber optic testing applications or network restorations. Optical loopback adapters provide system test engineers a simple but effective way of testing the transmission capability and the receiver sensitivity of network equipment.įiber Optic Loopback is providing a media of return patch for a fiber optic signal. They are designed for testing, engineering and the burnin stage of boards or other equipment. SC MM Fiber Optic Loopback module patch cable OM1 62.5 / 125, OM2 50 /125 LSZH With Black Plastic Shellįiber Optic Loopback modules are also called optical loopback adapters.
