Fiber optic transceiver is to ensure that data packets can be converted from internal copper transmission to external fiber transmission, to ensure smooth transmission between different networks, with the rapid increase in network capacity demand, fiber optic transceiver from Gigabit fiber optic transceiver towards 10 Gigabit evolution, while its types are also derived from POE fiber optic transceiver, non-managed, managed, mini and other fiber optic transceivers. Easy days optical communication to introduce these fiber optic transceivers.

Types of Fiber Optic Transceivers

1. PoE Fiber Transceiver

PoE fiber optic transceiver uses a dedicated ASIC chip to achieve data line speed forwarding, fast speed, strong anti-interference, can provide ultra-low latency data transmission, completely transparent to network protocols. PoE fiber optic transceivers not only extend existing network fiber cabling distances, but also provide power to PD devices such as IP phones, IP cameras, and wireless devices over UTP copper.

PoE fiber optic transceiver adopts classic Realtek Ethernet data switch core, packet buffer area and 96KB, ultra-high backplane bandwidth of 1.6G, packet forwarding rate of 0.1488Mbps. Support MAC address table depth of 1K. Stable operation, stable data line transmission, and strong anti-interference ability, signal conversion speed and stability. It can automatically detect and identify PD equipment conforming to IEEE802.3af standard, and supply power to it. Support overcurrent protection, overvoltage protection, PD power classification energy-saving mechanism, real-time protection of external equipment.

2. Unmanaged and Managed Ethernet Fiber Transceivers

Ethernet optical fiber transceiver can efficiently realize the conversion between 10/100M or 10/100/1000M Ethernet electrical port and optical port. The port is automatically compatible with half/full duplex mode. It can transmit long-distance data and video signals through optical fiber, which is convenient for network upgrade and flow control. It adopts strict industrial design to ensure stability and practicality. It has ultra-low transmission delay and line speed forwarding capability. Flexible Ethernet scalability even in harsh industrial environments.

Unmanaged optical fiber transceiver electrical interface supports self-adaptation, supports VLAN and QoS, frame length does not exceed 1536B, has low power consumption (3W), strong stability and heat dissipation. It can be freely converted between full duplex and half duplex, and data can be received and transmitted simultaneously, and can be transmitted and received in a single way.

3. Mini Ethernet Fiber Transceiver

Mini Ethernet fiber optic transceiver low power consumption, stable performance, fast transmission rate, RJ45 port 10/100/1000M can automatically identify, support SFP port 1000Base, no manual operation, and support mode conversion between half duplex and full duplex. At the same time, it comes with high-quality chips, with efficient allocation and decoding processing capabilities, recognition capabilities, strong anti-interference capabilities, and longer transmission.

Optical fiber transceiver and optical module, optical fiber jumper connection scheme:

Optical fiber transceiver is photoelectric converter, which is a kind of network equipment that converts electrical signal and optical signal to each other. It conforms to IEEE80.2.3 series Ethernet standard and can be connected with optical module and optical fiber jumper. It is used in network environment such as optical fiber broadband service and network monitoring of large companies.

1. Ethernet fiber optic transceiver

When we are laying out a large network, due to the limited transmission distance of the network cable (the maximum transmission distance of the network cable is 100m), relay equipment or fiber optic jumpers are generally selected to complete the wiring, and fiber optic jumpers are generally used.

When the optical fiber transceiver is connected to the network, the optical cable is first introduced from the outdoor to the indoor, the cable core and the tail fiber of the optical cable are fused, and then the fused optical fiber is placed in the optical fiber fusion splice tray in the ODF optical fiber distribution frame, and then the coupler is used to connect it with the optical fiber jumper;

Second, plug the SFP optical module into the optical interface of the fiber optic transceiver, and then connect the fiber optic transceiver using fiber optic jumpers; finally, connect the fiber optic transceiver to the switch using network jumpers. After power up, the Ethernet fiber optic transceiver lights up to indicate a successful connection.

2. POE fiber optic transceiver

When we are arranging the network monitoring system, we can directly use the POE fiber optic transceiver to power the webcam, WIFI, etc., which is an affordable network cabling solution.

Firstly, two SFP optical modules are inserted into the optical interface of POE optical fiber transceiver and SFP port of gigabit switch respectively, and then connected by optical fiber jumper;

Secondly, use the network jumper to connect the network camera and POE fiber optic transceiver electrical interface (RJ45);

Finally, use the network jumper to connect the switch to the network hard disk recorder, the network hard disk recorder and the host. After power-on, POE fiber optic transceiver lights up to indicate successful connection.
