    Single-mode/multi-mode optical module and its usage

    Where are the application of single/multimode fiber and single/multimode optical module? (1) Single-mode fiber can make the fiber be directly transmitted to the center, and is generally used for long-distance data transmission; in multi-mode fiber, optical signals propagate through multiple chann...

  • The difference between single/multimode fiber for industrial-grade fiber media converter

    The difference between single/multimode fiber for industrial-grade fiber media converter

    Fiber media converter can be divided into single-mode fiber and multi-mode fiber according to the transmission mode in the fiber. The most fundamental difference between single-mode  and multi-mode is the transmission distance. Industrial grade fiber media converter: the difference between singl...

    Solutions to common faults of PDH optical transceiver

    Permanent failure:    For permanent faults, a loop can be used at one end, and the other end can be displayed from the switch or judged section by section and layer by layer with a transmission analyzer. 1. Transmission alarms appear in pairs. For example, if RJA (remote alarm) occurs on the A si...

  • Do you know how to choose the right SFP transceiver?

    Do you know how to choose the right SFP transceiver?

    The SFP transceiver is one of the best fiber optics on the market. It’s regarded as the “modern workhorse” of the networking world because it is easily interchangeable, repaired, and replaced in a variety of designs. The hot-pluggable capability alone makes these devices desirable to designers in...
