Optical Transceivers
Optiunik manufactures the full ladder of pluggable optical transceivers from 10G SFP+ to 800G OSFP, all programmed with original-vendor compatibility codes — Cisco IOS XE, Juniper, Arista EOS, NVIDIA / Mellanox, Brocade, Huawei, H3C, Extreme, and others — and verified on real switch hardware before shipping. Common reaches we stock include SR / SR4 multimode (50–300 m), LR / LR4 / DR4 / FR4 single-mode 1310 nm (2–10 km), ER / ZR long-haul (40–80 km), plus tunable DWDM, BiDi, and CWDM variants for metro and access networks. Modules are DDM / DOM-enabled with full digital diagnostics over I²C, and every unit ships with an Optiunik-branded test report capturing optical Tx/Rx power, extinction ratio, and BER. For 200G / 400G / 800G modules we offer PAM4 DR / FR / LR / ZR variants and OSFP / QSFP-DD form factors suitable for AI clusters, spine-leaf fabrics, and HPC interconnects. Custom firmware coding, breakout labels, and printed compatibility lists are provided per OEM request.
