FIBERSTAMP’s 400G Single-Wavelength DCI BOX Coherent Subsystem Solution delivers a high-capacity, cost-efficient optical transport platform for data center interconnect (DCI) and metro applications. It uses the latest 400G QSFP-DD ZR/ZR+ coherent optical modules integrated in a modular DCI BOX chassis to support scalable, long-reach coherent links with simplified deployment and enhanced spectral efficiency.
Core Solution Overview
- Single-wavelength 400G coherent transport for reliable long-distance links.
- Built around 400G QSFP-DD DCO ZR+ coherent engines, compliant with OpenZR+ standards for broad interoperability.
- Supports a white-box chassis design (1U or 2U), enabling flexible integration into standard optical networks.
- Achieves up to 6.4 T total transmission capacity in a compact, modular system.
Key Components
- 400G QSFP-DD DCO ZR+ Coherent Module:
- Hot-pluggable QSFP-DD form factor.
- Supports native 400GE and multi-100G services (e.g., 4×100G).
- Full C-band tunable optics with LC duplex connectivity.
- Compliant with relevant hardware and management standards.
- 400G QSFP-DD Muxponder Engine:
- Converts up to four 100G client services into a single coherent 400G link.
- Ideal for networks needing service aggregation and simplified optical layer utilization.
