With the popularity of optical fibers, the application of fiber optic transceivers is increasing. But many people find it difficult to judge the quality of fiber optic transceivers when choosing them, apart from comparing prices and brands. Now Shanhai will tell you how to choose a satisfactory fiber optic transceiver.
Regarding the price, products on the market priced at a few hundred yuan are sufficient to meet the needs of general enterprises, except for special industries such as telecommunications, military, coal mining, etc. In addition to price, consideration should also be given to the compatibility between the product and the surrounding environment, as well as the stability and reliability of the product itself. Otherwise, no matter how low the price is, it will be useless to buy it. In addition, we also need to pay attention to some technical details:
(1) Can the transceiver support full duplex and half duplex. Some chips on the market can only use full duplex and do not support half duplex. If connected to a utility switch (N-Way Switch) or hub (HUB), it can easily cause serious collisions and packet loss.
(2) Is there a security device to prevent packet loss. Many manufacturers often use the Register data transmission mode to reduce costs when making fiber optic transceivers. The biggest disadvantage of this method is that the data transmission is unstable and prone to packet loss; A better approach is to use buffer circuit design to avoid data loss.
(3) Has a temperature test been conducted. Fiber optic transceivers generate heat during use, and if the ambient temperature is too high, the transceiver may not function properly, leading to packet loss, crashes, and other malfunctions. The operating temperature range of fiber optic transceivers is an important factor to consider carefully!
(4) Does it comply with the IEEE802.3 standard. Fiber optic transceivers should comply with the IEEE802.3 standard, otherwise compatibility issues may arise when connecting to other network devices.
(5) The manufacturer's after-sales service. The after-sales cost is often a point that customers easily overlook. Imagine, if your device breaks down and the manufacturer doesn't solve the problem for a long time, what kind of losses would it cause?
(6) Carefully observe the appearance of the product. Check if the fiber optic module casing of the product is old, glossy, or shows signs of wear and tear. Many manufacturers in the current market use second-hand or refurbished fiber optic modules on equipment such as fiber optic transceivers and switches in order to make huge profits. The use of these second-hand fiber optic module products poses great risks to network transmission, such as contamination of the optical path of the fiber optic module, which affects signal transmission and reduces transmission quality. And the decrease in transmission quality will affect the receiving sensitivity and easily cause phenomena such as data loss. In addition, the use of second-hand fiber optic modules also results in a discount on their service life, and there may be situations such as component failure at any time.
Equipment Selection
Shenzhen Guangte Communication Technology Co., Ltd
GT-111 series 100Mbps fiber optic transceiver
10/100M adaptive fast Ethernet fiber optic transceiver (also known as optoelectronic dielectric converter), with a unique Link Failure PassThrough function for optoelectronic two end link connection failure alarm, mainly used for fiber extension of metropolitan Ethernet.
The 10/100M Ethernet fiber optic transceiver can convert 10Base-T and 100Base TX twisted pair electrical signals into 100Base FX optical signals. It extends the transmission distance of the network from the copper wire limit of 100 meters to 120 kilometers, and achieves data transmission between the optical and electrical network connection media by using two network transmission technologies: data link layer 2 storage and forwarding mode or physical layer 1 through mode. Supports dual fiber multimode, dual fiber single-mode, and single fiber single-mode fiber transmission.
In order to adapt to various working environments, the SH-111 series transceiver is not only designed with a structure that can be placed on a desktop or hung on a wall, but also with a 19 inch 14/16 slot cabinet structure that can accommodate customers for centralized power supply and space saving.
