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 supplied 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. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.

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

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.

Shipping and Lead Time

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

Reliability Control

From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
