The 400G QSFP112 FR4 Optical Transceiver is used in 400G Ethernet data center and cloud network environments, where it provides a 425Gbps (4x 106.25Gbps) link over SMF up to 2km. The Duplex LC/UPC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

This product is designed and tested to comply with QSFP-112 MSA, CMIS Rev 4.0, IEEE 802.3cu, OIF-CEI-112G-VSR-PAM4. It plugs into any standards-based QSFP112 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

To order, quote QSFP112-FR4-400G together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.

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.

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.

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.

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.
