Applications
Designed for 400G Ethernet data center and cloud network environments, the 400G OSFP 8x 50G PAM4 Finned Top to 4x QSFP28 4x 25G NRZ Breakout AOC, 5m carries 400Gbps between OSFP (IHS/Finned Top) to 4x QSFP28 interfaces. This unit is stocked in 9 standard lengths from 1m (3ft) to 30m (98ft). By fanning one port out to 4x QSFP28, it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 8x 50G-PAM4 to Quad 4x 25G-NRZ modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: CMIS 4.0, SFF-8636, IEEE 802.3bs-400GAUI-8, IEEE802.3bm-CAUI-4, OSFP MSA, SFF-8661, SFF-8639. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
Order reference: part number OSFP-400G-4Q4XNAO. Standard supply covers 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 20m (66ft) and 30m (98ft). Custom length production is available for project requirements.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
