Bahamas Coherent Optical Module OSFP

The Bahamas OSFP coherent optical module is a high-speed, pluggable transceiver supporting 400G to 800G coherent transmission for data center and metro/regional DWDM networks.

Overview

The Bahamas OSFP module is part of the OSFP (Octal Small Form-factor Pluggable) family of coherent optical transceivers designed for high-capacity data transport. It supports multi-rate coherent transmission, including 400G, 600G, and 800G line rates, and is compatible with Dense Wavelength Division Multiplexing (DWDM) networks for both short-reach Data Center Interconnects (DCI) and long-haul metro/regional applications . The module uses a duplex LC interface and is mechanically compliant with the OSFP MSA standard .

Key Features

• Data Rates: Supports 400G, 600G, and 800G coherent line rates, with future OSFP1600 modules supporting up to 1.6Tb/s using 8x200Gb/s host interfaces .
• Reach: Capable of up to 120 km for 800ZR and beyond 1000 km for 800G ZR+ over amplified DWDM links .
• Thermal Management: Integrated heatsink design allows for 30+ Watt thermal performance, ensuring reliable operation in high-density data center environments .
• Compatibility: Backward compatible with OSFP800 modules and supports IP-over-DWDM applications directly from router or switch ports .
• Diagnostics: Digital diagnostic monitoring is available via I2C interface, providing real-time monitoring of optical and electrical parameters .
• Standards Compliance: Compliant with OSFP MSA, IEEE802.3db, and IEEE802.3ck standards .

Applications

• Data Center Interconnect (DCI): High-speed links between data centers up to 120 km.
• Metro and Regional Networks: Long-haul coherent transmission over existing DWDM infrastructure, supporting 800G ZR+ for distances exceeding 1000 km.
• High-Density Networking: OSFP modules enable pluggable optics in routers and switches, supporting scalable, high-bandwidth deployments.

Future Developments

The OSFP MSA is advancing toward OSFP1600 and OSFP-XD modules, which will support 1.6Tb/s per module and address thermal and electrical challenges for next-generation data centers . These developments ensure that OSFP coherent modules like Bahamas will continue to scale with increasing bandwidth demands while maintaining backward compatibility.

Summary

The Bahamas OSFP coherent optical module is a high-performance, pluggable solution for modern data center and telecom networks, offering multi-rate coherent transmission, long reach, robust thermal management, and full OSFP MSA compliance. It is suitable for both current 400G/800G deployments and future high-capacity 1.6T networks, making it a versatile choice for scalable optical interconnects .
