Wide CompatibilityIt's fully compliant and compatible for Juniper networks QSFP28 MSA, SFF-8665 and SFF-8636, IEEE 802.3 ba 100GBASE-LR4 and IEEE 802.3 bm CAUI-4 standards, coding as Juniper JNP-QSFP-100G-LR4 ^^ 100G QSFP+ LR4100GBASE-LR4 QSFP+ transceiver module, up to 10km over a standard pair of single mode fiber (SMF) with duplex LC connectors, long distance transmission over singlemode fiber 1310nm, 4 independent full-duplex channels, Hot Pluggable, DDM Built-in digital diagnostic functions, Class 1 FDA Laser Safety and RoHS Compliant. 0C to 70C (32 to 158F) ^^ Connector&Cable100GBASE-LR4 QSFP+ transceivers use duplex single mode SMF fiber patch cables with duplex LC connectors hot pluggable, but not SC connector.
It support single mode fibers OS2 SMF up to 10km. ^^ SR4 vs LR4The main difference between 100GBASE-SR4 QSFP28 and 100GBASE-LR4 QSFP28 is the transmission distance and connector type. The 100GBASE-SR4 QSFP28 supports 70m@OM3/100m@OM4 transmission with MTP/MPO connector; while the100GBASE-LR4 QSFP28 supports 10km@SMF transmission with LC duplex connector. ^^ Widely Application It's fully compliant QSFP28 MSA, RoHS, IEEE 802.3 ba 100GBASE-LR4 and IEEE 802.3 bm CAUI-4 standards, widely used on Infiniband QDR and DDR interconnects, large data centers Interconnect, high-performance computing networks, enterprise core and distribution layer applications.
