Optical Transceiver and Ethernet Extender: How to choose?

1. What is a fiber optic transceiver?

Fiber optic transceiver is a cost-effective and flexible device, mainly used to convert twisted-pair electrical signals into optical signals (or vice versa) to extend the transmission distance. The common types are optoelectronic transceivers and optical-optical transceivers. They can easily add fiber optic cabling to the copper cabling system, extending the service life of the original cabling system. Optical fiber transceivers are mainly used in network environments where Ethernet cables cannot be covered and optical fibers must be used to extend the transmission distance.


2. What is an Ethernet extender?

The Ethernet extender can convert the Ethernet signal into a digital simulation language, and then convert the signal back to the Ethernet. This helps to use coaxial cable, network cable or single twisted pair cable (such as Cat5e/6/7 network cable) 10M, 100M, Gigabit Ethernet to more easily connect to the alarm circuit, T1/E1 circuit, RS -232, RS-422, RS-485, CCTV (closed circuit television) and CATV (community antenna television). With the ethernet network extender, there is no need to install new cable infrastructure, saving a lot of cost and time.


Fiber optic transceivers and Ethernet extenders can be flexibly installed in a local area network to extend the transmission distance due to their compact size and independent power supply, but there are still differences between them.


3. When to choose fiber optic transceivers or Ethernet extenders?

Fiber optic transceivers can be widely used in various industries to provide connections between optical fibers and copper cables to extend the transmission distance. Common application environments include enterprise networks, campus networks, and metro Ethernet.


Ethernet extenders can be used to extend your local area network. If you already have a twisted pair or telephone line in your local area network, using a pair of Ethernet extenders may be the most suitable choice. The Ethernet extender can extend the various copper cables that have been installed, thereby reducing the consumption of human and financial resources caused by the installation of new cables.
