How are fiber optic transceivers connected?

Before understanding how fiber optic transceivers are used, we need to understand what fiber optic transceivers are. Optical fiber transceivers, also known as photoelectric converters, are transmission media conversion units that convert electrical signals into optical signals and then into electrical signals. They are mainly used to help optical fibers connect the last mile to the metropolitan area network and realize Ethernet The conversion between the twisted pair cable and the Ethernet optical signal.

The role of fiber optic transceivers

Optical fiber transceivers are mainly used to help long-distance transmission of electrical signals. They are generally used in long-distance transmission scenarios that cannot be reached by network cables. Therefore, optical fiber transceivers are used for transmission, and optical fiber transceivers need to be used in pairs. The usage method is as follows: connect the network cable to the transmitting end of the optical fiber transceiver, then use the optical fiber to connect the transmitting end and the receiving end, and then connect the receiving end to the device with the network cable.

Features of fiber optic transceivers

1) Provide ultra-low latency data transmission;

2) Completely transparent to network protocols;

3) Using special ASIC chips to realize wire-speed data forwarding. Programmable ASIC integrates multiple functions into one chip, which has the advantages of simple design, high reliability, and low power consumption, which can enable the device to obtain higher performance and lower cost;

4) Rack-type equipment can provide hot swap function, which is convenient for maintenance and uninterrupted upgrade;

5) The network management equipment can provide functions such as network diagnosis, upgrade, status report, abnormal situation report and control, and can provide a complete operation log and alarm log;

6) Most of the equipment adopts 1+1 power supply design, supports ultra-wide power supply voltage, and realizes power protection and automatic switching;

7) Support a wide operating temperature range;

8) Support complete transmission distance (0~120km).

Advantages of fiber optic transceivers

When talking about fiber optic transceivers, we may compare them with optical port switches. Here we will compare fiber optic transceivers with optical port switches.

cost price

The use of optical fiber transceivers and ordinary switches is cheaper than optical port switches, and the slowdown of the optical port and the use of optical modules will cause one or even multiple electrical ports to be unavailable. There will be a gap in cost and utilization.

mix and match

The fiber optic transceivers produced by different manufacturers have no problems in interconnection. If equipment failure occurs, products produced by other manufacturers can be used instead, which is convenient for maintenance. The optical modules used in optical port switches are different. Since there is no unified standard for optical modules, if the optical module fails, it is necessary to use the original matching optical module.

Ring Backbone

The ring backbone network uses the SPANNING TREE 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 to form 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. The ring backbone network can form a broadband virtual private network for industries such as finance, government, and education.

chain backbone

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.

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, which can provide a smooth upgrade scheme 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 an inexpensive half-duplex HUB on the client side, which can reduce the networking cost of the client side dozens of times and improve network operators. competitiveness.

The above are some introductions of optical fiber transceivers, but when there are half-duplex devices, the transmission distance of optical fibers is limited. One thing we need to pay attention to is that the length of the fiber cannot be used normally within the maximum distance supported by single-mode fiber or multi-mode fiber. This requirement can only be achieved when the connected devices are full-duplex devices. is correct.
