The optical splitter is one of the important passive devices in the optical fiber link, and mainly plays the role of splitting. It is generally used in the optical line terminal OLT and the optical network terminal ONU of the passive optical network to realize the optical signal splitting. The op...

There are many types of patch cords and pigtails. It is worth noting that fiber pigtails and patch cords are not a concept. The main difference between fiber optic patch cords and fiber optic pigtails is that only one end of the fiber optic pigtail has a movable connector, and both segments of th...

The PoE switch is a switch that supports power supply to the network cable. Compared with the ordinary switch, the power receiving terminal (such as AP, digital camera, etc.) does not need to be wired for power supply, and the reliability of the entire network is higher. The difference between Po...

As an important part of optical network transmission, optical fiber module functions as photoelectric conversion, so that signals can be transmitted in optical fibers. So, do you know how to distinguish whether an optical fiber module is single-mode or multi-mode? Here are a few ways to distingui...

Optical modules can be classified into single-fiber and dual-fiber according to the number of interfaces. Dual-fiber optical modules have two optical fiber interfaces, and single-fiber optical modules have only one optical fiber interface. In addition to the difference in optical fiber interfaces...

The optical fiber transceiver essentially only completes the data conversion between different media, which can realize the connection between the computers or switches at both ends within 0-100KM, but there are more extensions in practical applications. Then, what are the specific applications o...
