Definition of Fiber Optic Transceiver
Fiber optic transceiver is a kind of Ethernet transmission media conversion unit that interchanges short-distance twisted pair electrical signals and long-distance optical signals, also known in many places as a photoelectric converter (Fiber Converter). The product is generally used in the actual network environment where Ethernet cable cannot cover and fiber must be used to extend the transmission distance and is usually located in the access layer of broadband metropolitan area network applications; for example, high-definition video image transmission for surveillance and security projects; and also plays a great role in helping to connect the last mile of fiber-optic lines to the metropolitan area network and the outer layer of the network.
The role of Fiber Optic Transceivers
Fiber optic transceivers are generally used in real-world network environments where Ethernet cables cannot be covered and fiber must be used to extend transmission distances, and also play a huge role in helping to connect fiber optic last-mile lines to metropolitan networks and beyond. With fiber optic transceivers, also provides an inexpensive solution for users who need to upgrade their systems from copper to fiber, for those who lack the money, manpower, or time. The purpose of a fiber optic transceiver is to convert the electrical signal we want to send into an optical signal and send it out and at the same time, be able to convert the received optical signal into an electrical signal and input it into our receiving end.
Features of Fiber Optic Transceivers
- Provides ultra-low latency data transmission.
- Completely transparent to network protocols.
- Data wire-speed forwarding is achieved by using a dedicated ASIC chip. The programmable ASIC concentrates several functions on one chip, which has the advantages of simple design, high reliability, and low power consumption, enabling the device to get higher performance and lower cost.
- The shelf-type device can provide a hot-plug function, which is easy to maintain and upgrade without interruption.
- Network manageable equipment can provide network diagnosis, upgrade, status report, abnormal condition report, and control, etc., and can provide complete operation log and alarm log.
- equipment mostly adopts a 1+1 power supply design, supports ultra-wide power supply voltage, and realizes power protection and automatic switching.
- Support ultra-wide working temperature range.
- Support complete transmission distance (0~120km).
Advantages of Fiber Optic Transceivers
When it comes to fiber optic transceivers, people often can’t help but compare fiber optic transceivers with switches with optical ports, the following is mainly about the advantages of fiber optic transceivers compared to optical port switches.
First of all, fiber transceiver plus common switch is far cheaper than an optical port switch in price, especially some optical port switches will lose one or even several electrical ports after adding optical modules, which can make operators reduce the preliminary investment to a great extent.
Second, because most of the optical modules of the switch are not a unified standard, so once the optical module is damaged it needs to be replaced with the same module from the original manufacturer, which brings great trouble to the later maintenance. But fiber optic transceiver equipment from different manufacturers in the interconnection and interoperability has been no problem, so once damaged can also be replaced with products from other manufacturers, maintenance is very easy.
Also, fiber optic transceivers are more complete than optical switches in terms of transmission distance. Of course, optical switches also have advantages in many aspects, such as unified management, unified power supply, etc.
