The 40 QSFP+ LR4 2KM is a 4x10G hot-pluggable optical transceiver module. It is designed for up to 2KM optical communication applications over multimode fiber using 4 wavelength of CWDM via LC connectors. The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm as members of the CWDM wavelength grid defined in ITU-T G694.2.
It is compliant with QSFP+ MSA, IEEE 802.3bm 40GBASE-LR4 standard.
It is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. With these features, this easy to install, hot swappable transceiver is suitable to be used in various applications, such as high-performance computing networks, enterprise core and distribution layer applications, data centers.
