QSFP-100G-SM-SR is the Cisco 100G CWDM4 Lite QSFP transceiver, listed by Cisco as 2 km over SMF with a 10 to 60 C operating range. It sends 100 Gbps over four lanes at 1271, 1291, 1311 and 1331 nm on G.652 single-mode fiber with a duplex LC connector.
Cisco gives the reach as up to 2 km with an optical link budget of 4.2 dB, which it says can cover patch panel loss in data centers. Power consumption is 3.5 W and the pull tab is green. Per lane, transmit power is -6.9 to +2.5 dBm and receive power is -11.1 to +2.5 dBm. It is a Class 1 laser product. Only PC or UPC patch cords are supported on duplex single-mode links.
Cisco states that QSFP-100G-SM-SR interoperates with QSFP-100G-CWDM4-S. That sibling shares the 2 km reach, wavelengths, LC connector, 3.5 W draw and green pull tab, with a transmit range of -6.5 to +2.5 dBm and a receive range of -11.5 to +2.5 dBm per lane.
Other 100G modules are in the Cisco modules category, such as the QSFP-100G-SR4-S multimode module and the QSFP-100G-LR4-S 10 km module.
