Cisco Compatible 40GBASE-LR4 QSFP+ 1310nm 20km DOM Duplex LC SMF Optical Transceiver Module
Cisco QSFP-ELR4-40G Compatible 40GBASE-ELR4 QSFP+ Optical Transceiver Module (SMF, 1310nm, 20km, LC, DOM)
The QSFP+ module is designed for use in 40GBASE Ethernet throughput up to 20km over single mode fiber (SMF) using a wavelength of 1310nm via duplex LC connectors. This transceiver is compliant with SFF-8436 QSFP+ MSA and RoHS standards. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP+ MSA, to allow access to real-time operating parameters. With these features, this easy to install, hot swappable transceiver is suitable to be used in various applications, such as data centers, high-performance computing networks, enterprise core and distribution layer applications
Note: The FS P/N is changed from QSFP-LR4-40G-20 to QSFP-ELR4-40G, but the product is the same. Only the FS P/N has been changed.
