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. The MPO-12/APC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Compatibility with Arista Networks systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of OSFP-400G-VSR4.
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
Order this product as OSFP-VSR4-400G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
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.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
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.
