  1. Why Do You Need a PON Power Meter

    Why Do You Need a PON Power Meter

    The requirements for testing fiber optic networks will vary according to the specific type of network and the overall testing requirements of the network designer. Regardless of the type, two basic or general-purpose optical test equipment will be used; an optical time domain reflector or OTDR, and a pair of optical test equipment called a power meter and a light source. These tests are usually in units of "dB". The term dB is the expression of attenuation or power loss when the fiber is transmitted from the terminal to a point along the fiber path. After connecting the optical fiber to the active device, all tests are in dBm. Active devices will transmit actual or real optical power at a specific wavelength, and use 1mW as a reference.

    PON power meters are essential for field technicians to install or maintain any type of PON network. The PON power meter can simultaneously test the upstream and downstream wavelengths of 1490nm, 1550nm and 1310nm through optical fiber, as we

  2. Things you should know before buying an OTDR

    Things you should know before buying an OTDR

    OTDR is the abbreviation of Optical Time Domain Reflectometer. It is a fiber tester used to characterize optical networks supporting telecommunications. It can be used to measure loss, optical return loss (ORL) and optical distance on fiber links. In addition, OTDR can provide a graphical representation of the entire optical fiber link by providing the graphical trajectory characteristics of the fiber under test. However, there are too many OTDR brands on the market. Choosing the right OTDR for your application can be challenging. So the purpose of this article is to provide some suggestions when choosing an OTDR. Hope it can help you.

    Why do you need OTDR?
    As we all know, fiber optic testing is a basic procedure to ensure that the network is optimized to provide reliable and robust services without failure. Therefore, there are two reasons for the need for OTDR.
