  • How does SFP+ optical transceiver work with 10-Gigabit switch?
    How does SFP+ optical transceiver work with 10-Gigabit switch?
    • November 19. 2021

    In today's Internet era, both enterprise network deployment and data center construction are inseparable from optical transceivers and switches. Optical transceivers are mainly used to convert electrical and optical signals, while switches are used to forward photoelectric signals. Among many optical transceivers, the SFP+ optical transceiver is one of the most widely used optical transceivers. Wh...

  • How to use the media converter?
    How to use the media converter?
    • November 17. 2021

    Optical fiber media converter is also known as optical-to-electrical converter, its function as converting the optical and electrical signal. The transmission process is roughly: the electrical signals are converted into optical signals, transmitted through optical fibers, and then the optical signals are converted into electrical signals at the other end, and then connected to routers, switches a...
