Description
QSFP+ LR4 is designed to operate over single-mode fibre system using 4X10 CWDM channel in 1310 band and links up to 10km. The module converts 4 inputs channel of 10Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 40Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data. The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331nm. It contains a duplex LC connector for the optical interface and a 38-pin connector for the electrical interface. Single-mode fibre (SMF) is applied in this module. This product converts the 4-channel 10Gb/s electrical input data into CWDM optical signals (light), by a 4- wavelength Distributed Feedback Laser (DFB) array. The 4 wavelengths are multiplexed into a single 40Gb/s data, propagating out of the transmitter module via the SMF. The receiver module accepts the 40Gb/s optical signals input, and de-multiplexes it into 4 CWDM 10Gb/s channels. Each wavelength light is collected by a discrete photo diode, and then outputted as electric data after amplified by a TIA. The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP+ Multi-Source Agreement (MSA) and compliant to 40G QSFP+ LR4 of IEEE 802.3ba.FEATURES 4 CWDM lanes Mux/Demux design Up to 11.1Gbps Data rate per wavelength Up to 10km transmission on SMF Electrically hot-pluggable Digital Diagnostics Monitoring Interface Compliant with QSFP+ MSA with LC connector Case operating temperature range: 0°C to 70°C Power dissipation < 3.5 W APPLICATIONS 40G Ethernet Data Center and LAN STANDARDS Compliant to IEEE 802.3ba Compliant to SFF-8436 RoHS Compliant WARRANTY3-years limited warrantyTAA-approved SFPs available upon request, Contact us for more details.
