Axiom Memory 3AL82188AA-AX 400G FR4 QSFP-DD Optical Transceiver

Move 400 GbE traffic across up to 2 km of single-mode fiber using a QSFP-DD optical interface and duplex LC connector. The FR4 optical format combines four wavelength lanes across the 1271 nm to 1331 nm range, allowing a 400G link to run over a two-fiber LC path instead of a parallel-fiber arrangement. This suits high-capacity switch-to-switch and router-to-router fiber connections where existing single-mode cabling terminates in duplex LC panels. Install the 3AL82188AA-AX in a QSFP-DD port intended for 400G FR4 optics. It carries Alcatel-Lucent Nokia-compatible coding for systems that require that vendor association. Its 2 km reach places it between short in-room interconnects and longer campus optical spans, while the single-mode, duplex-LC media requirement keeps the optical path explicit. Match the optic type at both ends of the connection to establish a compatible 400G FR4 link. For 400G FR4 deployments, this module provides a compact pluggable alternative to parallel-fiber optics where two-fiber single-mode infrastructure is already present. The QSFP-DD form factor fits high-density 400G network interfaces, and the duplex LC connection simplifies patch-panel presentation compared with multi-fiber connector systems.
