Description
The AddOn Arista Networks® Compatible OSFP-400GB-DCO-ZR-AR-AO is a high-performance 400GBase-ZR coherent optical transceiver designed for next-generation long-haul and metro data center interconnect applications. It delivers 400 Gbps Ethernet throughput over single-mode fiber (SMF) with distances of up to 40 km, using a tunable laser operating across the C-band spectrum (1528.77 nm to 1567.13 nm).
Engineered for maximum performance and reliability, this hot-swappable OSFP module supports OIF 400ZR standards and integrates advanced coherent optics technology, including a 7 nm DSP, tunable nano-ITLA laser, and Coherent Optical Subassembly (COSA). With support for both 100 GHz and 75 GHz channel spacing, full CMIS 5.0 and C-CMIS 1.0 compliance, and robust thermal protection, it ensures efficient operation in high-density networking environments.
Featuring digital optical monitoring (DOM) for real-time performance insights and built to meet TAA, RoHS, and Telcordia GR-468-CORE reliability standards, this transceiver is ideal for high-capacity cloud, enterprise, and carrier networks. Every unit is programmed, uniquely serialized, and rigorously tested to guarantee 100% compatibility and seamless interoperability with Arista Networks® equipment.
