Single Mode Fiber Optic Cable and Its Application

1. The types and models of single mode fiber optic cable transceivers are diversified

The development of fiber optic networks has become an inevitable trend. Therefore, enterprises now directly use fiber optic as the transmission medium to establish the backbone network when building their own network. Many enterprises also upgrade the original network based on business needs.

However, due to the consideration of capital, manpower or time, many enterprise users urgently need a cheap solution, which can not only reduce the cost but also maximize the value of the original equipment.

Therefore, the practice of many enterprises is that the backbone network is fiber optic cable, and the transmission medium of the internal LAN is generally copper wire and twisted pair. But how to connect the local area network with the fiber optic backbone network?

This requires conversion between different ports, different lines, and different fibers to ensure connection quality.

Fiber optic transceiver is an Ethernet transmission media conversion unit that interchanges short-distance twisted-pair electrical signals and long-distance optical signals. It is also called a photoelectric converter or Fiber Converter in many places.

Simply put, one end of the single mode outdoor fiber cable is connected to the optical transmission system. The other end (user end) comes out with a 10/100M Ethernet interface. The main principle is to realize communication through photoelectric coupling, and there is no change to the encoding format of the signal.

Fiber optic transceivers have the advantages of providing ultra-low latency data transmission, being completely transparent to network protocols, using dedicated ASIC chips to achieve wire-speed data forwarding, and using 1+1 power supply design for equipment. Support ultra-wide power supply voltage to realize power protection and automatic switching.

At the same time, it supports an ultra-wide operating temperature range and a complete transmission distance of 0 to 120 kilometers.

Single mode fiber optic cable transceivers can cover ranges from 20 kilometers to 120 kilometers. It should be pointed out that due to the different transmission distances, the transmitting power, receiving sensitivity and wavelength of the fiber optic transceiver itself will also be different.

For example, the transmit power of a 20-kilometer fiber optic transceiver is generally between -15 and -7dB, and the receiving sensitivity is -30dB, which is suitable for the wavelength of 1310nm. And 120 kilometers of fiber optic transceivers transmit power between -5 ~ 0dB, receiving sensitivity of -38dB, using the wavelength of 1550nm.

2. Applications of single mode fiber optic cable transceiver

The bandwidth potential of single mode in single-mode fiber optic transceivers makes it the best choice for high-speed and long-distance data transmission.

Single-mode fiber optic transceivers are especially suitable for various broadband data networks such as telecommunications, cable television, railways, military, financial securities, customs, civil aviation, shipping, electric power, water conservancy and oil fields. And the fields that require high-reliability data transmission, or the establishment of IP data transmission private network.

Single mode fiber optic cable transceiver is the most ideal application equipment for broadband campus network, broadband cable TV network and intelligent broadband community fiber-to-the-building and fiber-to-the-home. Solve the problem of data transmission over long distances.
