The 400G Cluster Optical Flexible Card (SKU CR5M0OFCK050) is a high-density, programmable optical interface module designed to deliver 400 Gbps aggregate throughput for carrier and data center networks.
This card supports 400 Gbps full-duplex performance, up to 8×50 Gbps lanes, LC/APC multi-mode or single-mode interfaces, <6 W power consumption, and a MACsec-capable programmable PHY.
The card is compatible with major 400G-enabled switches, routers, and coherent transport platforms that accept the standard flex-form factor interface.
Slide the card into a compatible flex-form factor slot, ensure the retention latch clicks into place, connect the optical cables, and verify link status via the chassis management interface.
It supports LC/APC connectors for single-mode applications and MPO/MTP connectors for high-density parallel optics in multi-mode deployments.
The card supports IEEE 802.3bs 400GBASE-LR8, 400GBASE-SR8, OIF CEI-28G, and optional MACsec encryption for secure transport.
The card delivers a sustained 400 Gbps aggregate data rate with line-rate forwarding across all ports.
It employs advanced DSP-based equalization, forward-error correction (FEC), and real-time optical power monitoring to maintain reliable links up to 10 km.
The card consumes less than 6 W in standard operation, making it one of the most energy-efficient 400G optical modules available.
The card is rated for industrial environments from –5 °C to 70 °C (23 °F to 158 °F) with humidity up to 85% non-condensing.
The card features an MTBF exceeding 3 million hours, ensuring high availability in mission-critical networks.
Its modular design allows hot-swappable deployment in multi-slot chassis, supporting seamless capacity expansion from 100G to 400G per slot.
