Applications
The Arista Compatible 400G OSFP VSR4 Optical Transceiver is used in 400G Ethernet data centers, HPC and machine learning clusters, where it provides a 400Gbps link over MMF up to 30m@OM3/50m@OM4 or OM5. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. 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
To order, quote OSFP-VSR4-400G 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.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
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.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
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.
