The range of active optical devices such as SFP or QSFP28 is increasing rapidly, thanks to the adoption of many standards and multi-source agreements (MSA) across the telecom industry. With so many devices available, it can therefore become challenging to assess the quality of a transceiver or an amplifier, whether it is for a manufacturer on a production line or for a service provider choosing a transceiver vendor. This challenge is complexified by the fact that all optical transmitters, whether a 100 Gbit/s line card or a pluggable, includes optical subassemblies that generate the optical signal, and each of those subassemblies warrants different kinds of tests.
This webinar, sponsored but EXFO, will shed light on the testing of active optical devices in manufacturing and lab environments, ranging from the most basic component—the laser—up to complete optical networking systems (WDM or other), including devices like transmitter optical subassemblies (TOSA) and erbium-doped fiber amplifiers (EDFA). More specifically, it will discuss spectral testing, the measurement of optical power as a function of wavelength and related parameters, which is a key part of thorough optical source qualification. For system vendors and service providers, a good spectral testing procedure prevents the use of detective optical modules, which could lead to errors in transmission, useless truck rolls and network downtime. For manufacturers, spectral testing ensures that products delivered to customers are of top quality. This webinar will outline the relevant spectral tests for each type of optical sources and devices.
