With our Free Vendor & Compatibility Exchange program, one part number covers all your needs. Deploy once, adapt forever with zero inventory risk.
The Perks:
Free Vendor Swaps
Need to change from Cisco to Juniper? Arista to Dell? Exchange optics between supported vendors at no cost.
Free Compatibility Exchanges
Changes to fiber type or reach? Exchange between SFP modules of the same bandwidth at no cost.
3-Year Advance Replacement Warranty
Full coverage, zero hassle. If a module fails, we cross-ship a replacement immediately.
Free Shipping Both Ways
Never pay for ground shipping on orders, warranty claims, or compatibility exchanges.
Engineered for production fiber networks
Every NetAPI module is built to its MSA specification SFF-8472 for SFP/SFP+/SFP28, SFF-8636 for QSFP+/QSFP28, and CMIS 5.x for QSFP56, QSFP112, QSFP-DD, and OSFP. Tx/Rx power, laser bias current, module temperature, and supply voltage are all exposed as digital diagnostics for real-time monitoring via switch CLI, SNMP, or NETCONF.
Each SKU is validated against a live OEM golden unit on the target switch firmware, then burned in for 24 hours at +55 °C with traffic looping at line rate. Modules that drift outside their alarm thresholds during burn-in are pulled before they ship.
Cross-vendor compatibility, end-to-end
EEPROM identity bytes are programmed for the target platform, Cisco IOS-XE/NX-OS/Meraki, Juniper Junos, Arista EOS, Dell OS10/SmartFabric, HPE Aruba CX, NVIDIA Spectrum/Cumulus, Extreme EXOS, plus 25+ more. Modules enable cleanly with no service-unsupported-transceiver overrides, no Junos commit warnings, no EOS interface errors.
Interoperability is verified switch-to-switch on real production firmware before each SKU is released. We track vendor security-byte changes across major OS releases (NX-OS 10.x, EOS 4.30+, Junos 22+) and refresh coding workflows as those releases hit GA.
1G to 800G, one supplier
Full coverage of the optical transceiver family: SFP (1G), SFP+ (10G NRZ), SFP28 (25G NRZ), QSFP+ (40G), QSFP28 (100G NRZ), QSFP56 (200G PAM4), QSFP112 and QSFP-DD (400G PAM4 in 4-lane and 8-lane variants), and OSFP (800G PAM4). Reach classes from VCSEL-based SR on multi-mode fiber through DFB-based LR/ER and coherent DSP-based ZR/ZR+ on single-mode.
Direct-attach copper (DAC), active copper (ACC), and active optical cables (AOC) for short-reach intra-rack; LR/ER/ZR for inter-rack, inter-DC, and metro DCI. RS-FEC (528,514) at 25G/100G and RS-FEC (544,514) at 200G/400G/800G are enabled by default per platform.
Optics deployed across the networks that matter
From industrial-temp SFPs in trackside cabinets to 800G OSFP modules in AI training clusters, NetAPI optics are engineered for the operating conditions of the network you're actually running.
