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.
Sopto provides SPT3302 OTDR with a special price. Competing with JDSU OTDR, SPT3302 with almost the same function but a cheaper price.You can contact to us for more about Optical Time Domain Reflectometer,Price,Product,Description.
This article Introduces some popular fiber optical fast connectors . Firstly, One of a common type of fiber optical connector is the FC/PC . This connector has a pin that connects to the female component and screws tightly into place. Though these connectors have been used for a long time, in 2011, snap-type connectors, such as the LC and the SC connectors are becoming more popular. Secondly, the ST fiber-optic connector is one of the most common . Major telecommunication companies often use this type of connector because it is easy to install and relatively inexpensive. Loss of data can occur with this type of connector if the cable is misaligned with the female component.
The difference between indoor fiber cable and outdoor fiber cable Compared with outdoor fiber optic cable, indoor fiber optic cable experience less temperature and mechanical stress, but they have to be fire retardant, emit a low level of smoke in case of burning. And indoor fiber cables allow a small bend radius to make them be amendable to vertical installation and handle easily. Most indoor fiber optic cables are tight buffer design, usually they consist of the following components inside the cable, and the FRP which is non-metallic strengthen member, the tight buffer optical fiber, and the cable outer jacket. The trend is to use LSZH or other RoHS
Optical fiber access is refers to between the terminal and the user using optical fiber as a transmission media. The ways of optical fiber access include active optical access and passive optical access. The main technology of fiber optic user network is light wave transmission technology. The development multiplexing technology for optical fiber transmission very fast and the majority have been in practical use, such as Time-Division Multiplexing (TDM), Wavelength Division Multiplexing (WDM), Frequency Division Multiplexing (FDM) and Code Division Multiplexing (CDM). FTTC, FTTZ, FTTO, FTTB, FTTH can be divided according to the degree of fiber-depth user. Optical fiber
