Familiar with QSFP-40G-SR4 40GBASE-SR4 COMPATIBLE 40GBASE-SR4 ("short range") is a port type for multi-mode fiber and uses 850nm lasers. It's used for short range fiber connection. Its Physical Coding Sublayer 64b/66b PCS is defined in IEEE 802.3 Clause 82 and its Physical Medium Dependent PMD in Clause 86.
CISCO QSFP-40G-SR4 It uses four lanes of multi-mode fiber delivering serialized data at a rate of 10.3125 Gbit/s per lane. 40GBASE-SR4 has a reach of 100 m on OM3 and 150m on OM4. There is a longer range variant 40G-eSR4 with a
reach of 300 m on OM3 and 400 m on OM4. This extended reach is equivalent to the reach of 10G-SR.
