The function of OTDR
An OTDR (Optical Time Domain Reflectometer) is used in fiber optics to measure the time and intensity of the light reflected on an optical fiber.
An OTDR can detect such light loss and pinpoint trouble areas, making repairs easy. The more quickly trouble areas are identified and addressed, the less your fiber optic network will suffer from data transfer problems. More to the point, it is used as a troubleshooting device to find faults, splices, and bends in fiber optic cables, with an eye toward identifying light loss. Light loss is especially important in fiber optic cables because it can interfere with the transmission of data.
The OTDR is not perfect, of course. Critics charge that it can produce inaccurate results if two trouble spots are very close together or if the pulse has a long travel length. Experts also urge training in order to interpret the data correctly. Another factor is the relatively high price for a device that might be used only sparingly.
Proponents, however, counter that being able to pinpoint and address light loss points is well worth the price, both for the OTDR device and for the training needed to operate and properly understand the data that that OTDR records.

The plug and play PLC splitter modules . The PLC splitter module is mainly used in the Optical Distribution Network (ODN). The PLC splitter module is placed in the local convergence point (LCP) - the ODF cabinet or the fiber optical cross-connection cabinet. The PLC splitter module distributes the optical power of the main fiber into several-road to realize the multi-user access. This PLC splitter module is mainly designed for the ODF cabinets or the fiber optical cross-connection cabinet based on the telecom standard. The panel of the splitter has one or two FC/SC flanges as the input end of the fiber; and has many FC/SC flanges as the output end of the fiber. These flanges
The knowledge of the optical splitter loss for you to purchase fiber splitters. The optical splitter loss is divided into the insertion loss and the additional loss. The insertion loss of the optical splitter can be understood from this formula: Ai = -10log Pouti/Pin. “Ai” means the insertion loss of the “ith” output port. The “Pouti” is the optical power of the “ith” output port. And the “Pin” is the optical value of the input port. For the fiber optical couple, the additional loss is the quality indicator of the device manufacturing process to reflect the inherent loss of the device in the fabrication process. And
