400Gbase LR4

For metro networks and distributed data centers requiring robust 10km connectivity, our 400Gbase LR4 (400G QSFP-DD LR4) transceiver (Model MCR-6PSCLC-10) delivers uncompromising performance through cutting-edge photonic integration. Engineered for carrier-grade reliability, this solution combines industry-leading reach with exceptional signal integrity.

Precision Optical Engineering:

• High-Efficiency Bandwidth: Transmits 425Gbps payload via 4x106.25Gb/s optical lanes (aggregating 8x53.125Gb/s electrical PAM4 signals)
• Breakthrough Reach: Achieves 10km over standard single-mode fiber using duplex LC connectors
• Silicon Photonics Advantage: SIP transmitter enables superior thermal stability and signal consistency across 1271/1291/1311/1331nm LWDM channels

Critical Infrastructure Benefits:

► Carrier-Grade Reliability:

≤10W power consumption validated for 0°C to 70°C operation

BER < 10⁻¹² at maximum reach

► Operational Simplicity:

Hot-pluggable QSFP-DD form factor

CMIS 4.0 management with real-time DOM

► Fiber Optimization:

Eliminates amplification needs for ≤10km links

Technical Validation:

• IEEE 802.3cu compliant
• QSFP-DD MSA Rev 4.0 certified
• 96-hour thermal cycling (+85°C margin testing)
• Dispersion tolerance > 1,600 ps/nm

Target Applications:

• Metro DCI (Data Center Interconnects)
• 5G/6G xHaul transport
• Cloud gateway uplinks
• Financial network backbones

Q: What cables do I need?
A: Just standard two-strand single-mode fiber with LC connectors – the same type widely used in telecom networks. No special rewiring!

Q: Is this 400Gbase LR4 transceiver power-hungry for long distances?
A: Not at all. It uses ≤10W of power (like a bright LED bulb) and runs cool in standard data center temperatures (0°C to 70°C).

Q: Does it support industry standards?
A: Fully compliant with IEEE 802.3cu and MSA specifications – guaranteed to work with Cisco, Juniper, Nokia, etc.
