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. Its configuration varies since the fiber count is not always the same in different applications. As for the MTP/MPO loopback, it is mainly used for testing parallel optics, such as 40G and 100G transceivers. The LC and SC loopbacks are made with simplex fiber cable and common connectors it’s not difficult to understand their configurations. In testing fiber optic transceiver modules, the most commonly used are LC, SC and MTP/MPO loopback cables. Our fiber loopbacks are precision terminated and feature extremely low loss characteristics for transparent.
According to the optical connector type of the loopback, fiber loopback cables can be divided to LC, SC, FC, ST, MTP/MPO, E2000, etc. Fiber Optic Loopback Cables Available Factory-Direct Now In-Stock - Genuine Amphenol Fiber Optic Loopback Cables provide a simple and effective means of testing the capabilities of your optical networking equipment. Based on the fiber type used, there is single-mode loopback and multimode loopback, available for different polishing types. This designing is more compact in size and stronger in use. Some vendors provide improved structure with a black enclosure to protect the optical cable. Generally, a fiber loopback is a simplex fiber optic cable terminated with two connectors on each end, forming a loop. Before deciding which loopback cable to use, we should firstly know the structure and classification of fiber loopback cable.
