Applications
Built for 400G Ethernet data centers, HPC and machine learning clusters, this OSFP (IHS/Finned Top) module carries 400Gbps over MMF up to 30m@OM3/50m@OM4 or OM5 per link. With its MPO-12/APC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. For networks standardized on Arista Networks hardware, it is a drop-in equivalent of the OSFP-400G-VSR4. The link runs 8x50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Arista Networks part OSFP-400G-VSR4 and works in Arista Networks systems out of the box. Standards compliance covers CMIS 5.2, IEEE 802.3bs-400GAUI-8, OSFP MSA, IEEE 802.3 db-400GBASE-VR4.
Ordering Information
Our part number for this module is OSFP-VSR4-400G. 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.
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.
Logistics
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.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
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.
