Optical module technology: how to test the performance of Optical module?sfp transceivers module price

After installing the Optical module, testing its performance is an essential step. When the optical equipment in the entire network system is provided by a single supplier, if the network system can function normally, there is no need to test the sub components of the system separately. However, most of the subcomponents in current network systems come from different suppliers. Therefore, it is very important to test the compatibility and interoperability of optical devices, especially each Optical module. So, how to test the compatibility of Optical module? After reading this article, I think you will find the answer.

As we all know, the Optical module consists of a transmitter and a receiver. When the transmitter is connected to the receiver through optical fiber, if the error rate of the entire system does not achieve the expected effect, is it a problem with the transmitter or the receiver? Or there may be issues with the transmitter and receiver.

In fact, the transmitter and receiver of the Optical module will interact with each other. Therefore, the qualification criteria of Optical module is that any receiver can receive optical signals from the transmitter with the worst performance, and any transmitter can send optical signals that can be received by the receiver with the worst performance. Accurately defining the worst-case performance of a transmitter or receiver is a complex task. If the receiver needs to receive a certain amount of power to meet the system error rate requirements, then this power is the minimum transmission power of the transmitter; If the receiver can only withstand a certain amount of jitter capacity, then the jitter capacity is the maximum jitter tolerance of the transmitter. The test of Optical module is generally divided into four steps, mainly including the test of transmitter and receiver.
