    The color of the optical module pull ring corresponds to the transmission rate

    The color of the pull ring of the multi-mode optical fiber module with a transmission rate of less than 40G (excluding 40G) is generally black, while when it comes to 40G and above (including 40G), the color of the pull ring of the multimode optical fiber module is beige. One key method of visual identification is the color of the transceiver's pull tab, which corresponds to its wavelength. This article provides a professional guide on transceiver pull tab color codes by wavelength—spanning SFP, SFP+, CWDM, and BiDi modules—and introduces how LINK-PP standardizes.

  • Passive Optical Network Transmission Signal

    Passive Optical Network Transmission Signal

    Passive optical networks are used to simultaneously transmit signals in both the upstream and downstream directions to and from the user endpoints. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. Instead of running a separate fiber strand to every home or office, a PON shares a single fiber using optical. In a PON access network there are two end-points with active (powered) electronic transmission equipment, connected by passive (non-powered) equipment known as outside fiber plant. At the subscriber premises, there is an Optical Network Termination (ONT) device that terminates fiber and connects. Passive Optical Network (PON) stands as a foundational technology in the evolution of modern telecommunications, serving as the cornerstone for high-speed fiber-optic networks.
