As the demand for faster and more efficient data transmission continues to rise, 800G OSFP (Octal Small Form-factor Pluggable) modules represent the forefront of high-speed optical transceiver technology. Designed to address the needs of hyperscale data centers, cloud providers, and advanced enterprise networks, these modules provide ultra-high bandwidth and enhanced thermal performance. This article dives into the technical specifications and applications of four key 800G OSFP variants: 800G OSFP RHS SR8, 800G OSFP FINNED-TOP SR8, 800G OSFP FINNED-TOP DR8, and 800G OSFP FINNED-TOP FR8.
1. Key 800G OSFP Variants and Their Features
800G OSFP RHS SR8
RHS (Regular Heat Sink) Design: Optimized for standard heat dissipation needs, ensuring consistent performance in data centers with moderate thermal management capabilities.
SR8 (Short Range, 8 Lanes): Specifically designed for short-range data transmission applications, such as intra-data center connections.
Application: Suitable for connections within racks or between closely located servers and switches, offering high-speed data transfer over multimode fiber.
800G OSFP FINNED-TOP SR8
Finned-Top Heat Sink: Enhanced thermal dissipation capability for environments with higher power density and limited cooling.
SR8 Specification: Like the RHS SR8, it supports short-range communication but adds improved thermal handling for dense deployments.
Application: Ideal for high-density racks in hyperscale data centers requiring efficient cooling and short-distance connectivity.
800G OSFP FINNED-TOP DR8
DR8 (Data Rate, 8 Lanes): Designed for longer transmission distances compared to SR8, supporting single-mode fiber for greater reach.
Advanced Cooling: Equipped with a finned-top heat sink to ensure stable performance in environments with significant thermal challenges.
Application: Perfect for inter-data center connections and longer intra-data center links where single-mode fiber is necessary.
800G OSFP FINNED-TOP FR8
FR8 (Forward Reach, 8 Lanes): Tailored for medium-range transmission applications, bridging the gap between short-range SR8 and long-range DR8 modules.
Thermal Optimization: Finned-top design allows for deployment in thermally demanding setups, maintaining performance and reliability.
Application: Suitable for medium-distance networking applications, such as connections between data center buildings or across larger facilities.
