Fiber optic transceiver is an Ethernet transmission media conversion unit that swaps short distance twisted-pair electrical signals with long distance optical signals. It is also called converter gpon in many places. Well, what are the buying skills of fiber optic transceivers? Next, Primus IT optional transceiver factory will introduce the 7 major selection skills of fiber transceiver for you in detail. Let's have a look!
1. Functional test of the fiber optic transceiver's port
It mainly tests whether each port of optical transceiver can work normally in duplex state of 10Mbps, 100Mbps and half duplex state. At the same time, test whether each port can automatically select the highest transmission rate and automatically match the transmission rate of other devices.
2. Characteristics of cable connections for fiber optic transceivers
Fiber optic transceiver module mainly tests the connection ability between optical transceivers and other Ethernet and fast Ethernet compatible devices (including network cards, hubs, switches, optical network cards, optical switches). Requirements must be able to support the connection of compatible products.
3. Cable connection characteristics of fiber optic transceivers
First, test the connection capability of five types of network cables of 100m and 10m lengths, and test the connection capability of five types of network cables (120m) of different fiber transceiver brands. During the test, the optical transceiver optical port is required to have the connection capacity of 10Mbps, 100Mbps rate, and the maximum connection capacity must be able to connect to full duplex 100Mbps without transmission errors.
4. Transmission characteristics of fiber optic transceiver (transmission loss rate and transmission speed of packets of different lengths)
It mainly tests the packet loss rate of different data packets transmitted by the optical port of the optical transceiver and the connection speed at different connection rates. To test the packet loss rate, you can use the test software that comes with the network adapter. The test software is used to test the packet loss rate, the number of packet errors, and the number of packets sent and received at different connection rates when the packet size is 64, 512, number of packets sent and received must be more than 2,000,000. To test the transmission speed, you can use software such as Perform3 and Ping.
5. Compatibility of fiber optic transceiver to transmission network protocol
It mainly tests the compatibility of fiber optic transceiver to network protocols. It can be tested in Novell, Windows and other environments. It must test the following low-level network protocols, such as TCP/IP, IPX, NETBIOS, AND DHCP, and test the protocols that need to be broadcast. Fiber optic transceivers are required to support these protocols. (VLAN, QOS, COS, etc.)
6. Indicator state test for fiber optic transceiver
Test whether the status of the indicator is consistent with the description on the panel and the user manual, and whether it is consistent with the current status of the fiber transceiver.
7. Measure the fiber optic transceiver optical transceiver factory's after-sales service
Imagine if your device broke and the fiber optic transceiver manufacturer didn't fix the problem for several days. How much would you lose? Therefore, in order to make the after-sales service can timely and early response, it is recommended that we choose a professional brand company with strong strength, superb technical force and good reputation. Only the technical engineers of professional companies have rich experience in troubleshooting and more advanced tools for fault detection.
