Fiber optic network test and measurement equipment

1) Optical Fiber IdentifierIt is a very sensitive photodetectors. When you bend a fiber, some light will radiate from the 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 them from other fibers. Optical Fiber Identifier can not affect the transmission in the case of detection of the state and direction of light. To make this work easier, usually sending the test signal modulated 270Hz, 1000Hz or 2000Hz and into specific fiber. Most of the optical fiber identifier for the operating wavelength of 1310nm or 1550nm single-mode optical fiber 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 light laser diodes (red light) source, when the light into the fiber, if fiber breaks occur, connector failures, excessive bending, welding and poor quality, a similar failure, by launching the light into the fiber of the fiber can be visual fault location. Visual Fault Locator with continuous wave (CW) or pulsed mode of emission. The typical frequency of 1Hz or 2Hz, but it can work in the kHz range. The usual output of 0dBm (1Mw) or less, the working distance of 2 to 5km, and supports all common connector.

3) The optical loss test equipment (also known as light meter or power meter)To measure the loss of a fiber optic link, you need to launch calibrated at one end of the stability of the light, and read out at the receiver output power. Both devices constitute the optical loss test set. The synthesis of a light source and power meter instrument, often called the optical loss test set (which was also known as light meter). When we measure the loss of a link, you need to have a test light source operating at the sending end 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 the loss of two directions (because of a loss or to the connection and said optical transmission loss due to the asymmetry caused by). At this time, technical staff must exchange equipment and then another direction measurements.
