MikroTik XQ+31LC02D 100GBASE-LR4 QSFP28 Optical Transceiver
The MikroTik XQ+31LC02D is a high-performance 100GBASE-LR4 QSFP28 optical transceiver engineered for long-distance, high-speed data transmission over single-mode fiber (SMF). Designed for compatibility with MikroTik’s CCR2216, CRS504, CRS510, and CRS518 series, this transceiver provides reliable, high-bandwidth connectivity for demanding enterprise, data center, and ISP backbone networks.
Operating over four independent full-duplex channels, each supporting up to 25 Gbps, the XQ+31LC02D delivers an aggregate throughput of 100 Gbps over distances up to 2 km. It employs 1271, 1291, 1311, and 1331 nm wavelengths for parallel transmission and includes Digital Diagnostics Monitoring (DDM) to track real-time optical parameters such as temperature, voltage, and power levels. With robust performance across a wide temperature range and built-in EMI resistance, it ensures exceptional reliability even in challenging network environments.
