Applications
The 1.6T OSFP224 2x FR4 FL Optical Transceiver is used in 1.6T Ethernet data centers, HPC and machine learning clusters, where it provides a 1600Gbps link over SMF up to 2km. 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. The link runs 8x 200G-PAM4 modulation, which keeps it aligned with current 1.6T switch silicon.
Standards and Compatibility
Standards compliance covers OSFP MSA Specification Rev 5.1, CMIS 5.2, IEEE 802.3dj D1p3, IEEE 802.3dj D1p3. The unit works in any equipment with a standard Twin-port OSFP RHS/Flat Top interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
Ordering Information
Our part number for this module is OSFP-2FR4-1.6T-FL. 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.
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
