The 400G OSFP 8x 50G PAM4 Finned Top to 4x QSFP28 4x 25G NRZ Breakout AOC, 5m connects OSFP (IHS/Finned Top) to 4x QSFP28 ports at 400Gbps over Breakout AOC fiber at 850nm. Because the optics are built into the cable ends, installation is plug and play with no separate transceivers to manage, and airflow inside the rack stays unobstructed. It is well suited to 400G Ethernet data center and cloud network environments. Standard lengths run from 1m (3ft) to 30m (98ft).

The 400G OSFP 8x 50G PAM4 Finned Top to 4x QSFP28 4x 25G NRZ Breakout AOC, 5m is a 400Gbps active optical cable for OSFP (IHS/Finned Top) to 4x QSFP28 connections in 400G Ethernet data center and cloud network environments. This unit is available in 9 standard lengths from 1m (3ft) to 30m (98ft). The breakout design lets one high speed port feed 4x QSFP28, which raises port utilization and simplifies cabling in dense rows. 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.

This product is designed and tested to comply with CMIS 4.0, SFF-8636, IEEE 802.3bs-400GAUI-8, IEEE802.3bm-CAUI-4, OSFP MSA, SFF-8661, SFF-8639. It plugs into any standards-based OSFP (IHS/Finned Top) to 4x QSFP28 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

The standard part number of this assembly is OSFP-400G-4Q4XNAO. We supply this cable in 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 7m (23ft), 10m (33ft), 15m (49ft), 20m (66ft) and 30m (98ft). Custom lengths beyond this range can also be produced on request. Samples for testing can be arranged before bulk orders.

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.

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.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
