Network Converter Buying Guide

Network Converter WiKi

Network converter, also known as media converter, and fiber media converter, is an Ethernet transmission media conversion device that interchanges short-distance twisted-pair electrical signals and long-distance optical signals. Network converters are generally used in the actual network environment where the Ethernet cable cannot cover and optical fiber must be used to extend the transmission distance, and is usually located in the access layer application of the broadband metropolitan area network. 

How to Choose A Network Converter

In actual procurement, an important factor considered is price, especially small and medium-sized enterprises and SOHO offices. We believe that a product of several hundred yuan is enough to meet the needs of ordinary enterprises, except for special industries, such as telecommunications, military, etc. Of course, in addition to the price, we must also consider the compatibility between the product and the surrounding environment and the stability and reliability of the product itself. Otherwise, no matter how low the price is, it is useless to buy it. In order to enable you to select good products, some key points of procurement are listed as follows:

(1) Confirm if it can support full duplex and half duplex, because some chips on the market can only use full duplex environments and cannot support half duplex. If they are connected to other brands of switches (n-way switches) or hubs and use half duplex mode, they will cause serious collision and packet loss.

(2) Confirm if it has been tested with other optical fiber connectors. There are more and more network converters on the market. If the mutual compatibility of network converters of different brands has not been tested before, packet loss, too long transmission time, fast and slow will also occur.

(3) Confirm if it has a security device to prevent packet loss, because when making network converters, many manufacturers often use the register data transmission mode in order to reduce the cost. The biggest disadvantage of this method is that the data transmission will be unstable, resulting in packet loss, and the best way is to adopt the buffer line design, which can safely avoid packet loss.

(4) Check whether the product is subject to temperature test, because the network converter itself will produce high heat when used, and its installation environment is usually outdoors, so whether the network converter can operate normally when the temperature is too high (not greater than 50°C) is a very important consideration for users! What is the maximum allowable operating temperature? For a given equipment that needs long-term operation, this item is very worthy of our attention!

(5) Confirm if the product complies with IEEE 802.3 standard? If it does not meet the standard, there will be compatibility problems.

(6) Measure the after-sales service of the manufacturer. Imagine that if your equipment breaks down and the manufacturer hasn’t solved the problem for several days, how much will you lose? Therefore, in order to make the after-sales service respond in time and early, it is recommended that you choose a professional company with strong strength, superb technical force and good reputation in the region. Only the technical engineers of professional companies have rich experience in troubleshooting and advanced fault detection tools!

(7) When purchasing, carefully observe the appearance of the product to confirm whether the optical fiber module shell of the product is old, shiny or worn. Nowadays, in order to make huge profits, many manufacturers in the market use second-hand or old optical fiber modules on network converters, optical fiber switches and other equipment. The products using these second-hand optical fiber modules cause great hidden dangers to network transmission, such as the optical path of optical fiber modules is polluted, which will inevitably affect signal transmission and reduce transmission quality. The decline of transmission quality will also reduce the sensitivity of reception and cause data packet loss. In addition, the use of second-hand optical fiber modules will also discount the service life, and parts will fail at any time.
