Network Camera Selection Guide Fiber Transceiver

Fiber Transceiver www.szgzl400.com the data transmission limitations meter Ethernet cable broke, relying on the exchange of chips and large-capacity cache performance, while real non-blocking switching performance transmission, also provides a balance flow, isolate the conflict and error detection and other functions, to ensure high safety and stability of data transmission. So in a very long time fiber optic transceiver products will continue to be the actual networking indispensable part, I believe the future of fiber optic transceivers will move toward intelligent, high stability, network management, cost orientation continue to develop. How to choose a good fiber optic transceivers Method / function test main test port Each port is working properly at 10Mbps, 100Mbps duplex status, half duplex mode. And it should test whether each port can automatically select the highest transmission speed and automatically match the transmission rate of other devices. This test may be included in other test content. The main test compatibility testing fiber optic transceivers compatible with other Ethernet, Fast Ethernet, different equipment (including network card, HUB, Switch, optical cards, optical switches) connectivity between. Requirements must be able to support the connection of compatible products. Cable connection characteristic test fiber optic transceivers network cable supports. First, you should test the 100m, 10m length and other connectivity UTP cable, testing different brands UTP cable long (120m) connectivity. Optical transceiver test requirements ports 10Mbps, 100Mbps connectivity rate, the highest must be able to connect to full duplex 100Mbps, and can not there is a transmission error. Of 3 twisted pair may not be tested. Secondary tests may be included in other test content. Transmission characteristics (transmission loss rate of packets of different lengths, the transmission speed is mainly to test fiber optic transceivers Optical port transmission of different data packet loss rate, and the connection speed connections at different rates. You can use the card for the loss rate test software test strip should be tested under different connection speed, packet size in 64,512,1518,128 (optional) 1000 (optional) bytes in the case of loss, including the number of errors, including the number of received must Test transmission speed can use perform3, ping software above 2,000,000. whole transport network protocol compatibility of the main test the degree of fiber optic transceivers compatible network protocol, you can Novell, Windows and other environments In testing, we must test the following low-level network protocol TCP / IP, IPX, NETBIOS, DHCP, etc., the test required protocol broadcast Requirements fiber optic transceivers support these protocols (VLAN, QOS, COS, etc.). LED status indicator test test The state is the same panel, describing a consistent user manual, and whether the current state of the same fiber optic transceivers same.
