Wide CompatibilityIt's fully compliant and compatible for Juniper networks QSFP28 MSA, SFF-8665 and SFF-8636, IEEE 802.3ba 100GBASE-LR4 and IEEE 802.3bm 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. 0°C to 70°C(32 to 158°F)
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 802.3ba 100GBASE-LR4 and IEEE 802.3bm 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.
