How to Test a Fiber Optic Transceiver?
When optical transceivers was first deployed, verifying the performance of it was straightforward. The entire network was installed and owned by a single company, and if the system worked, extensive testing of the subcomponents was unnecessary. Today, however, most optical networks use components that may come from a variety of suppliers. Therefore, to test the compatibility and interoperability of each fiber optic transceiver becomes particularly important. How to test a fiber optic transceiver? This article may give you the answer. As we all know, basically, a fiber optical transceiver consists of a transmitter and a receiver. When a transmitter through a fiber to connect with a receiver but the system doesn’t achieve your desired bit-error-ratio (BER), is the transmitter at fault? Or, is it the receiver? Perhaps both are faulty. A low-quality transmitter can compensate for by a low-quality receiver (and vice versa). Thus, specifications should guarantee that a...
