Frequently asked questions
What is an optical fiber loop?
Optical fiber loop is a medium used to provide a return temporary circuit for optical fiber signal. It can provide a rich and easy to manage the fiber loop, effectively eliminate the bending loss, and is often used in the field of optical fiber testing or network recovery. To diagnose a problem in an optical network device. Sending a loop back to a network device one at a time is a separate technique for detecting a problem.
What types of fiber loop modules are there?
As with fiber cables, fiber loop modules can be classified by the type of fiber: single mode and multimode. The type of fiber can be 9/125 μm single mode fiber 50 / 125 μm multimode fiber. Or 62.5 / 125 μm multimode fiber.
What are the applications of fiber loop cables?
The typical use of fiber loopback cables is to use loopback testing to check the optical fiber receiver. Loop testing means the use of hardware or software devices to perform loopback testing. Feedback the received signal or data to the sender. Used as an auxiliary in debugging physical connection problems.
