Performance Over 150m Distance

They claim that the Cisco QSFP-40G-SR-BD transceiver works well up to a distance of 150 meters on OM3 multimode fiber. To accomplish this, the 40 Gbps link is operational over any application that needs a lot of bandwidth. And, of course, there is no distortion on the signal, which results in low bit error rates for high-efficiency data. This also means that the temperature when in use does not go beyond the limits prescribed, hence the prolonged performance, even more so in extreme environments.

LC Connectors and Multi-mode Fiber (MMF) Compatibility

The Cisco QSFP-40G-SR-BD transceiver is mainly focused on Mpo connectors and so it will be imperative to examine any use of LC connectors compatibility. There are adaptors that make it possible for the two connectors to connect into Mpo and Mo, making it very easy to use in places where there are LC termination Relays. It is essential that when one uses the multi-mode fiber, it should be of either OM3 or OM4 type, for these are necessary when optimal performance metrics of a transceiver are desired. Attention to the type of fiber and connector arrangement needed will also restrict the conditions in which LC connectors will be used to ensure optimal signal quality and the greatest throughput over the needed distances.
