What Is The Difference Between Singlemode SFP and Multimode SFP

by www.fiber-mart.com There are two types of SFP transceivers, Single-mode SFP and Multi-mode SFP, both work with a different kind of optical fiber. The Single-mode (also known as Mono-mode) fibers are used with Single-mode SFP transceivers, whereas Multi-mode optical fibers are used with Multi-mode SFP transceivers. Let’s discuss the difference [ Continue reading…]

The development of optical transceivers and their future

by www.fiber-mart.com Nowadays, when we look at the product- and funcionalityrange of optical transceivers , we owe it to a long technical development.   Since the beginning, all transceiver specifications are defined under non-proprietary standards of the Multisource Agreement (MSA) of the SFF Committee. This allows intercomptability of products from [ Continue reading…]
