This product is a transceiver module designed for optical communication applications ranging from 2 meters to 10 kilometers, compliant with the 40GBASE-LR4 specification of the IEEE P802.3ba standard. The module converts four 10Gb/s electrical input channels into four CWDM optical signals and multiplexes them into a single 40Gb/s optical transmission channel. On the receiver side, the module optically demultiplexes the 40Gb/s input signal into four CWDM channel signals and converts them into four channels of electrical output signals. The four CWDM channels have center wavelengths of 1271nm, 1291nm, 1311nm, and 1331nm, which comply with the CWDM wavelength grid as defined by ITU-T G.694.2. The module uses a duplex LC connector as the optical interface and a 148-pin connector as the electrical interface. To minimize optical dispersion in long-distance systems, the module must be used with single-mode fiber (SMF). The product is designed to meet the form factor, optical/electrical connections, and digital diagnostic interface requirements of the QSFP+ Multi-Source Agreement (MSA), and is capable of meeting the most demanding external operating conditions, including temperature, humidity, and electromagnetic interference.
