    What does the optical transceiver 2M mean, and what is the relationship between the optical transceiver E1 and 2M?

    Optical transceiver is a device that converts multiple E1 signals into optical signals. Optical transceiver is also called optical transmission equipment. Optical transceivers have different prices according to the number of E1 (that is, 2M) ports transmitted. Generally, the smallest optical tran...

  • What is the difference between Layer 2 and Layer 3 switches?

    What is the difference between Layer 2 and Layer 3 switches?

    1. Different working levels: Layer 2 switches work at the data link layer, and Layer 3 switches work at the network layer. Layer 3 switches not only achieve high-speed forwarding of data packets, but also achieve optimal network performance according to different network conditions.   2. The prin...

  • How to use fiber optic transceivers?

    How to use fiber optic transceivers?

    The function of fiber optic transceivers is to convert between optical signals and electrical signals. The optical signal is input from the optical port, and the electrical signal is output from the electrical port, and vice versa. The process is roughly as follows: convert the electrical signal ...

  • What is the difference between a switch and a fiber converter?

    What is the difference between a switch and a fiber converter?

    Optical fiber transceiver is a very cost-effective and flexible device. The common use is to convert electrical signals in twisted pairs into optical signals. It is generally used in Ethernet copper cables that cannot be covered and must use optical fibers to extend the transmission distance. In ...

  • What is Ring network redundancy& IP protocol?

    What is Ring network redundancy& IP protocol?

    What is Ring network redundancy? A ring network uses a continuous ring to connect each device together. It ensures that the signal sent by one device can be seen by all other devices on the ring. The ring network redundancy refers to whether the switch supports the network when the cable connecti...
