Optical transceivers have obvious advantages
Optical fiber transceiver is an Ethernet transmission media conversion unit that interchanges short-distance twisted-pair electrical signals and long-distance optical signals, and is also called a photoelectric converter in many places. With the rapid increase in the demand for network capacity, the increasing demand for network management by operators, the continuous upgrading of Ethernet transmission speed, the types and complexity of optical transceivers are developing at an alarming rate.
ZR Cable Optical Transceiver
Optical fiber transceivers mainly have the following three basic connection methods:
1. Chain backbone network
The chain-shaped backbone network can save a lot of backbone light quantity by using the chain-shaped connection. It is suitable for constructing high-bandwidth and low-cost backbone network in the edge of the city and its suburban counties. This mode can also be used for highways, oil and electricity transmission line environment. The chain-shaped backbone network supports IEEE802.1Q and ISL network characteristics, which can ensure compatibility with most backbone networks, and can build broadband virtual private networks for industries such as finance, government, and education. The chain backbone network is a multimedia network that can provide integrated transmission of images, voice, data and real-time monitoring.
2. Ring backbone network
The ring backbone network uses the SPANNINGTREE feature to build the backbone within the metropolitan area. This structure can be transformed into a mesh structure, which is suitable for high-density central cells on the metropolitan area network and forms a fault-tolerant core backbone network. The ring backbone network supports IEEE.1Q and ISL network features to ensure compatibility with most mainstream backbone networks, such as VLAN, TRUNK and other functions across switches.
3. User access system
The user access system uses 10Mbps/100Mbps self-adaptation and 10Mbps/100Mbps automatic conversion function, which can connect any user terminal equipment without preparing a variety of optical fiber transceivers, and can provide a smooth upgrade plan for the network. At the same time, using the half-duplex/full-duplex self-adaptive and half-duplex/full-duplex automatic conversion functions, you can configure a cheap half-duplex HUB on the client side, which can reduce the networking cost of the client side by dozens of times and improve the network operator. competitiveness. At the same time, the built-in switching core of the device improves the transmission efficiency of the access device, reduces network broadcasts, controls traffic, and detects transmission failures.
