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.
Sopto provides SPT3302 handheld OTDR and SPTH1400 handheld OTDR . The physical description of an OTDR most closely resembles a sort of handheld price scanner with cables attached. The user connects the cables to an optical fiber, in the same way that two drivers will connect vehicle batteries with jumper cables, and then reset the OTDR settings for whatever parameters are being used in the specific test. A typical OTDR test can take anywhere from ten seconds to three minutes. An OTDR takes advantage of the scattering of light in the optic fiber to make its measurements. The OTDR emits a high-power pulse that hits the fiber and bounces back. What comes back is measured, factoring in
As we all know FTTH terminal box is an indispensable accessory in FTTH construction. This product is wildly used in FTTH area. Usually Fiber Access Terminal can be used indoor and outdoor, dust proof and water proof. Today I will introduce one of Sopto FTTH terminal box, FTB-106C. FTB-106C is the upgrade version for FTB-104C, this terminal box is light and compact, especially suitable for protective connection of fiber cables and pigtails in FTTH. Widely used in the end termination of residential buildings and villas, to fix and splice with pigtails; Can be installed on the wall; May adapt variety of optical connection styles; Optical fiber can be managed effectively. And it’s
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.
