Laser source is the easiest fiber optic test equipment, it can rapid detect on each fiber distribution panel. These devices are useful for testing the connectivity of fiber link segment.
Laser Source is the first testing equipment should be used to test the performance of fiber-optic link segment. This equipment can be easily detected at both ends of the fiber. Marking of the fiber wiring errors or installation disk port wrong, with a laser source can save a lot of time.
The drawback is that the light emitted by such equipment level is low, so that the actual light into the fiber core is less a result of these long-distance transmission of light through it very difficult to be seen or can not see.
Visual Laser Source and visual fault locator is a simple fiber optic test equipment. This equipment can be used to locate a cable not marked or diagnostic cabling link fault exists. Visual laser Source and visual fault locator can test more than 5km in length fiber link segment, both devices to locate and deal with the failure of fiber-optic lines are saving.
Visual laser source can be a ceiling or on a fiber optic cable distribution panel identified, which is similar to the audio generator and audio amplifier function to perform when testing copper, this device allows people to put a cable from a set of cable was quickly identified.
Visual Laser Source can send a strong light can illuminate the cable core and the cladding, in fact, the light will pass through the cable jacket orange or yellow, the cable identified. The device can easily locate the cable has been laid to quickly identify unmarked cable.
Fiber Fault Locator can be identified in the fiber link failure device, this device functions like connectivity tester, which makes it possible to visually identify the fiber link is disconnected or fiber breakage. Fault locator light pulses generated much stronger than the flash, so long-distance lines in the diagnosis of cable fault, the fault locator advantage.
Fiber Fault Locator can produce visible light optical signal, making it possible to visually identify wiring errors and incorrect patch panel port connection, then you can solve the problem quickly, saving time saves money. LAN or other communication device for the transmission optical signal in the non-visible spectrum.
Optical Power Meter is a test fiber optic cabling link loss of the basic test equipment, which can measure the fiber cable optical power. Section of the fiber link, the transmission signal with a power meter can measure the loss and attenuation.
Most handheld optical power meter is a device, the test wavelength is 850nm and 1300nm, 850nm and 1300nm for multimode fiber cabling systems operating wavelength. Optical power meter to test and evaluate the building floor area wiring cables most commonly used test equipment.
Singlemode fiber optic power meter for testing the test wavelength is 1310nm and 1550nm, optical power meter and laser source used in conjunction with single-mode fiber optic power meter is a field test most commonly used devices.
Optical Loss Test Set Optical Power Meter and Fiber Test by light combined composition. Optical Loss Tester for link segment includes all the necessary testing fiber jumpers, connectors and couplers.
Optical Loss Tester is used to test single-mode fiber and multimode fiber optic cable. For testing multimode fiber optic cable loss tester has an LED light source, can produce 850nm and 1300nm light. For testing single-mode fiber optic cable loss tester has a "a laser light source, can produce 1310nm and 1550nm light.
Optical Time Domain Reflectometer (OTDR) is the most complex fiber optic test equipment. OTDR fiber loss testing can be performed, the length can also be tested. Furthermore, OTDR fiber link can determine the cause of the fault and the fault location.
There are two types:
(1) This type of comprehensive type OTDR highest price, but the best performance and most versatile.
(2) Small OTDR this type of lower prices, but functional decline compared to full type.
OTDR using a laser as the light source rather than the optical power meter using LED. This equipment measured after the optical signal is input optical pulse time required to return the test point, the test results can be used to calculate the distance of the fiber link.
OTDR is based on the echo scattering work, fiber optic connectors and connecting sub at the connection point will be part of the light reflected back. OTDR by measuring the amount of echo scattering to detect the link in the optical connector and the connecting sub. OTDR can also be scattered signal by measuring the echo return time to determine the link distance. OTDR these information to a graph printing end, the output data can be used to analyze the characteristics of the fiber link sections or as a file backup.
