Dell QSFP-40G-LM4 Compatible 40G-ET6401-LX4 QSFP+ Optical Use for Enterprise Core and Data Center(1310nm, 2km, LC, DDM, SMF/MMF)

This product is a transceiver module designed for optical transmission applications over both MMF and SMF with transmission distances of up to 150m on MMF (OM3) and 2kmon SMF.  The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 CWDMoptical signals and multiplexes them into a single channel for 40Gb/s optical transmission. The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311, and 1331nm as members of the CWDM wavelength grid defined in ITU-T G.694.2. It contains a duplex connector for the optical interface and a 148-pin connector for the electrical interface.
