What is dynamic range of OTDR
Dec 15 , 2022
The dynamic range of an OTDR determines how long of a fiber can be measured. It is listed as a dB value — larger values generally mean longer distance measurement capability. A test pulse needs to be strong enough to get to the end of the fiber to be tested, and the sensor has to be good enough to measure the weakest backscatter signals which come from the end of a long fiber. The combination of t...

Repair of the obstacle of the optical cable
Dec 01 , 2022
In the event of an obstacle in the optical cable line, every second must be used to temporarily adjust the circuit or deploy an emergency optical cable to temporarily rush to open the circuit, and forces should be organized as soon as possible to repair it. 1. Emergency repair 1) All optical cable lines in a certain direction are blocked Immediately and temporarily adjust all circuits or some main...

What is GPON and EPON
Nov 16 , 2022
Both gpon and epon belong to infinite light source network technology, referred to as PON, which includes gpon and epon. It is a high-tech technology for the development of fiber-to-the-home. The implementation of this technology can not only save backbone fiber resources and network levels, but also speed up network transmission and improve the pull-in capacity of broadband. It has more types of ...

What do "OLT", "ONU" and "PON" mean? What is the difference between the three?
Nov 08 , 2022
OLT: optical line terminal, a terminal device used to connect optical fiber trunks. ONU (Optical Network Unit) ， ONU is divided into active optical network unit and passive optical network unit. Generally, the equipment equipped with network monitoring including optical receiver, uplink optical transmitter and multiple bridge amplifiers is called optical node. The PON uses a single fiber to connec...

The introduction to OTDR begins with the cognitive curve
Aug 16 , 2022
OTDR is one of the most commonly used fiber optic measurement instruments and is widely used in the measurement, construction, maintenance and acceptance work of fiber optic cable projects. Although OTDR is widely used and is a common instrument for many installation and maintenance teams and engineering teams, but due to the OTDR curve expression is not intuitive enough, there are still many prac...
