100GBASE CWDM4 Lite QSFP Transceiver 2km Over SMF 10-60°C Cisco QSFP-100G-SM-SR 10-3220-01
Cisco QSFP-100G-SM-SR Transceiver's Overview
QSFP28-100G Optical modules provide these highlights:
•Hot-swappable input/output device that plugs into a 100G Gigabit Ethernet Cisco QSFP port
•Interoperable with other IEEE-compliant 100GBASE interfaces where applicable
•Certified and tested on Cisco QSFP-100G ports for superior performance, quality, and reliability
•High-speed electrical interface compliant to IEEE 802.3bm

The QSFP28 SM-SR is for “Single-Mode fiber Short Reach” applications and is also known as “CWDM4-Lite”. A variant of CWMD4-S, its operating temperature range is +10 to +60°C instead of the standard commercial temperature range of 0 to 70°C.
Like CWDM4-S, SM-SR supports 100G link lengths of up to 2km over duplex G.651 SMF and accepts duplex LC connectors.
However, its optical link loss budget is 4.2 dB instead of 5.0 dB as specified by the CWDM4 MSA. At 4.2 dB, the link budget offers the ability to support the optical loss from patch panels in a data center environment. SM-SR is interoperable with CWDM4-S.
