Fiber optic test and measurement equipment

1) Optical Fiber Identifier

It is a very sensitive photodetector. When you bend a fiber, some light will radiate from the fiber core. The light will be detected by optical fiber identifier, technical staff can be based on these multi-core optical fiber or single fiber patch panel to identify it from other fiber. Optical Fiber Identifier can not affect the transmission in case of detection of the state and direction of light. To make this easier, usually sending the test signal modulated 270Hz, 1000Hz or 2000Hz and into a particular fiber. Most of the fiber used to identify the wavelength of 1310nm or 1550nm single-mode fiber optic cable, Optical Fiber Identifier is the best macro bending technology can be used online to identify and test fiber optic cable in the transmission direction and power.

2) Fault Locator (failure tracker)

This device is based on visible laser diode (red light) source, when the light into the fiber, if the fiber breaks occur, connector failures, excessive bending, welding and poor quality, similar to the failure, by the light launched into optical fiber can be of Visual fault location. Visual fault locator in a continuous wave (CW) or pulse mode firing. The typical frequency of 1Hz or 2Hz, but can also work in the kHz range. The output power is typically 0dBm (1Mw) or less, the working distance of 2 to 5km, and supports all of the universal connector.

3) optical loss test equipment (also known as the light meter or power meter)

To measure the loss of a fiber optic link, you need to end the stability of light emission calibrated and read out at the receiver output power. Both devices constitute the optical loss tester. The synthesis of a light source and power meter instrument, often referred to as optical loss test set (which was also known as light meter). When we measure the loss of a link, you need to have a transmitter operating in the test light source and another person at the receiving end with a power meter to measure, so that can only come to one direction on the loss of value.

Usually, we need to measure both directions of the loss (because of the existence of the connection loss, or the cable transmission loss that is due to the asymmetry caused by). At this time, technicians have to exchange equipment and then another direction measurements.
