Today’s data center market requires extensive use of optical module products to connect servers, switches, and storage devices. Bandwidth and bandwidth characterization remain critical for multimode fiber applications. Industry organizations and manufacturers are working together to develop standards to develop more accurate ways to characterize the actual performance of fiber optics. For example, in TIA, the meaning and value of VCSEL weights are re-evaluated, which is critical to estimating fiber bandwidth.
In IEEE802.3, the limitations of THE PAM-4 multi-wavelength transmission and the new link model are being studied. The basic part of any fiber optic cable is the connector. The impact of the connector is critical. Poor connectors affect the system not only by introducing low noise, but more importantly by reducing bandwidth capacity. Noise or bandwidth losses can be several times higher than losses. As a result, people are actively involved in all standards to ensure that the standards for fiber and connectors are consistent with system performance.
