How To Chose The Good Optical Ttransceiver?

April 29. 2016

With the development of optical telecom market, more and more customers begin to pay attention to the stability and reliability of the optical transceiver . There are three kinds of optical transceivers on the market now:

* Original optical transceiver

* Second-hand optical transceiver

* Compatible optical transceiver

As we know, the price of the original optical transceiver is rather expensive, many manufacturers can only be discouraged.

As for second-hand optical transceiver, although it’s price is relatively low, the quality can’t be guaranteed. It often will be abnormal after six months in use.

Therefore,many manufacturers have turned their attention to the compatible optical transceiver. Indeed,the performance of compatible optical transceiver is almost the same as the original optical transceiver. While the price is several times cheaper than the original optical transceiver.This is also why the compatible optical transceiver are so popular Currently .However, the quality of goods is not easy to identify, so the customer got some bad one , it hurt the customer deeply. In order to protect the benifits of the customers and friends, Here ETU-Link Technology Co., Ltd will share with you some details about the way of selecting optical transceiver.

The first question,how do we distinguish between new optical transceiver and used optical transceiver?

Second-hand optical transceiver will happen some issues after six months or one year. The reason is unstable optical power and the decline in the optical sensitivity and other matters. If you have the Optical Power Meter, you can check the output power whether meet the specification. If the difference is too large, it maybe chose the second-hand optical transceiver.

Then observe the working status after selling. The service life of a normal optical transceiver is 5 years,it is very difficult to see the optical transceiver is good or bad in the first year,but it can be seen out in the second or third year of use. Here, ETU-Link Technology Co., Ltd can guarantee that all optical transceivers we supply are guaranteed for 3 years. If it appears the non-human damage performance fault within warranty period, we can provide free repair/replacement to solve your worries.

And then see the compatibility between the optical transceiver and device.Customers need to communicate with the suppliers before the purchase,tell them need to use the device on which brand. In order to ensure that customers can buy the optical transceiver with good performance, ETU-Link Technology Co., Ltd will conduct a variety of tests for all compatible optical transceivers before shipment, including Material testing, Product parameter testing, Distance testing, Switch compatible testing and Burn-in testing, it will be good for guaranting its compatibility and operability.

Finally,we also need to see the temperature adaptability of the optical transceiver. When the module working will cause a little heat, but not so hot. Its general working environment is in the date center or on the switch. The temperature is too high or too low will affect its optical power, optical sensitivity and other parameters. Generally the temperature range of optical transceiver is at 0~70°C. If extremely cold or hot environment, we need to use the industrial optical transceiver at -40~85°C. ETU-Link Technology Co., Ltd will guarantee the the stability of the industrial products from the requirement of the hardware, Physical cooling and Temperature compensation software.

The installation of optical transceiver:

If you found that the function of optical transceiver is invalid in the processing, don’t worry, be careful inspection and analysis the specific reasons.

There are two main types of failure of the optical transceiver, transmitting end failure and receiving end failure. The most common reasons are the following aspects:

1)The optical transceiver port exposed in the air, dust cover the insection and pollution;

2)The section of optical connector has been contaminated, then cause the optical transceiver port is secondary pollution;

3)The section of pigtail operate improper bring scratched etc;

4)The bad optical connector will lead to problem too.

Therefore,after the proper selection of optical transceiver,you also need to pay attention to the cleaning and protection in all of the processing. After the installation, put the dust cap when there is stop working. Because if the optical port is not cleanning, it is possible to affect the quality of the signal, and may lead to LINK problems and error problems.

ETU-Link Technology Co., Ltd have been devoted to provide our customers optical transceivers with high performance.Hope our customers will be satisfied with our products and service. Our continual pursuit is win your moving！
