Applications
Built for next generation InfiniBand XDR fabrics and large scale AI clusters, this Twin-port OSFP IHS/Closed Finned Top module carries 1600Gbps over SMF up to 2km per link. With its Dual Duplex LC/UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. 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
This product is designed and tested to comply with OSFP MSA, CMIS 5.1, IEEE P802.3dj, OIF 224G-VSR. It plugs into any standards-based Twin-port OSFP IHS/Closed Finned Top port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
Our part number for this module is OSFP-2FR4-1.6T. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.
How We Pack
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.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
Quality Assurance
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.
