Fiber optic transceiver to ensure that data packets converted from copper wires inside the external optical fiber transmission, to ensure the smooth transfer between different networks, with the rapid increase in the demand for network capacity, toward the optical transceiver from optic transceivers Gigabit Gigabit evolution, but also the type of fiber optic transceivers POE, unmanaged derived, managed, and other mini-fiber transceiver. It is easy to introduce several sky optical communication transceivers, respectively.
Fiber Optic Transceiver
1. PoE fiber transceiver
PoE fiber optic transceiver uses a dedicated ASIC chip wire-speed forwarding of data, high speed, immunity to interference, can provide ultra-low-delay data transmission, completely transparent to the network protocol. PoE optical transceiver can not only expand the existing network cabling from the fiber, but also through UTP copper provide power to the IP phone, IP camera, and wireless devices PD device.
Fiber optic transceiver using the classical PoE Ethernet switch Realtek core, and a packet buffer area 96KB, 1.6G ultra backplane bandwidth, packet forwarding rate 0.1488Mbps. Support 1K MAC address table depth. Stable, smooth data transmission lines, and the anti-interference ability, high-speed stability signal conversion. It can automatically detect and identification of IEEE802.3af PD devices, and its power supply. Support overcurrent protection, overvoltage protection, PD power classification saving mechanisms, real-time protection external devices.
2. unmanaged and managed Ethernet optical transceiver
Unmanaged and managed Ethernet optical transceiver can achieve high efficiency conversion between 10 / 100M or 10/100 / 1000M Ethernet electrical port and an optical port that automatically compatible half / full duplex mode, the far through the optical fiber data and video signal transmission distance, easy to upgrade the network to implement traffic control, rigorous design to ensure the stability of industrial, practical, ultra-low transmission delay and speed forwarding capability, even in harsh industrial environments can be achieved flexible Ethernet extension.
Unmanaged fiber transceiver supports adaptive electrical interface, the QoS and VLAN support, the frame length does not exceed 1536b, having a low power consumption (3W), high stability and heat dissipation. You can freely switch between full-duplex and half-duplex, can simultaneously receive and send data, but also a single sender and a single receiver.
3. Mini Ethernet optical transceiver
Mini Ethernet optical transceiver low power consumption, stable performance, fast transmission rate, RJ45 terminal can automatically identify between 10/100 / 1000M, support 1000Base SFP ports, without manual operation, and the support half-duplex and full-duplex mode between conversions. While the high quality of the chip comes, having a processing capability of efficient allocation decoding, recognition, anti-interference ability, further transmission.
Optical transceiver and an optical module, an optical fiber jumper connection scheme:
Fiber optic transceivers is the photoelectric conversion device, an electrical and optical signals to convert each network device, in line with standard Ethernet IEEE80.2.3 series, may be connected to the optical module, the optical fiber jumpers, used in large company's optical broadband business, network monitoring and other network environments.
1. Ethernet optical transceiver
When we large network arrangement, due to the limited transmission distance of the network cable (cable maximum transmission distance of 100m), selecting a relay apparatus usually accomplished jumper wire or a fiber, while in use generally to optical fiber jumper transceiver .
In the optical fiber access network transceiver, first of all to the cable introduced from outside the room, the cable core and cable pigtail is welded, and then fusing the optical fiber is placed a good optical fiber distribution frame ODF in the fiber splicing tray, recycling a coupler connected to the fiber optic jumpers;
Next, the SFP optical module is inserted into the optical interface fiber optic transceivers, and then using an optical fiber jumper to connect fiber optic transceivers; finally, the use of fiber optic patch cords to the switch and the transceiver is connected. After power, Ethernet optical transceiver lights indicates successful connection.
2. POE fiber transceiver
When we arranged network monitoring system, can be directly used as a fiber transceiver POE webcam, WIFI and other power supply, it is an affordable solution for network cabling.
The first, the two optical modules are inserted POE SFP optical transceiver SFP optical interface port gigabit switch and then using an optical fiber jumper to connect them;
Secondly, the use of patch cords connected to a network camera and POE fiber transceiver electrical interface (the RJ45);
Finally, switches and network DVR, network DVR and hosts using patch cords to connect to. After power, POE optical transceiver lights indicates successful connection.
