In Straight-Through cable both the end is terminated with the same standard i.e.

Two types of Ethernet cable connection are made using EIA/TIA-568-A and EIA/TIA-568-B standard In EIA/TIA-568-A the eight wire are arranged in Orange-White, Orange, Green-White, Blue, Blue-White, Green, Brown-White, Brown.Īn easy way to remember color code is in odd places (1,3,5,7) color with white strip are present. In EIA/TIA-568-A the eight wire are arranged in Green-White, Green, Orange-White, Blue, Blue-White, Orange, Brown-White, Brown. Ethernet cable color coding as standardized by EIA(Electronic Industries association) and TIA(Telecommunication Industry Association) there are two standard EIA/TIA-568-A and EIA/TIA-568-B. In UTP cable consist of 4pair or 8 wire of different color that is used to terminate on RJ45 or 8P8C connector. In addition, to separate by fiber types, single-mode loopback (9/125) and multimode loopback (50/125, 62.5/125) are deployed for the application.Ethernet cable which is used to connect networking devices through UTP cable and end is terminated with RJ45 connector. Now it is the most popular loopback with low cost but high performance. Its connector is compliant to IEC, TIA/EIA, NTT and JIS specifications. Another frequently used type is SC fiber optic loopback. Having a low insertion loss, low back reflection and high precision alignment, LC fiber optic loopback is widely used all over the world. LC fiber optic loopback complies with the RJ-45 style interface. Categorized by connectors, fiber optic loopback has SC, LC, MTRJ, E2000 types, etc. You may find that loopback also has different types of optical connectors and fibers. And the looped space is reduced for an easier usage and economic package. As for fiber optic loopback module, the biggest difference is that it has a enclosure to protect the inside cable.

When sticking the connectors together, the cable will shape like a loop. It is equipped with two fiber optic connectors on each end of the cable. Fiber optic loopback cable is the traditional fiber optic loopback with a visible cable. Generally, fiber optic loopback cable and fiber optic loopback module are both fiber optic loopbacks. So, what is exactly the fiber optic loopback? By diagnosing the problems of optical equipment, fiber optic loopback provides an easy way to test the performance of the optical network devices.
