Q1. What is the OSFP-800G-SR8 Finned Top module?
A: The OSFP-800G-SR8 Finned Top is an 800Gbps OSFP optical transceiver designed for short-range, multimode fiber (MMF) links, supporting eight parallel 850nm PAM4 lanes and equipped with dual MPO-12 connectors and a finned-top housing for enhanced thermal management.
Q2. What does "SR8" mean in OSFP-800G-SR8?
A: SR8 refers to "Short Reach" over multimode fiber with 8 parallel lanes, each operating at approximately 106.25 Gbps (PAM4 modulation) at an 850nm wavelength.
Q3. What is the maximum transmission distance?
A: It supports up to 60 meters over OM3 fiber and 100 meters over OM4 fiber when host Forward Error Correction (FEC) is enabled.
Q4. What connector and fiber type does it use?
A: The module utilizes dual MPO-12/APC connectors over 50/125µm multimode fiber (OM3/OM4).
Q5. Is this module compatible across different equipment brands?
A: Yes, it complies with the OSFP MSA and IEEE 802.3db standards and is compatible with equipment from Cisco, NVIDIA, Arista, Asterfusion, and other vendors supporting generic OSFP optics.
Q6. Does this module support hot-swapping?
A: Yes, it is fully hot-swappable, allowing insertion or removal without shutting down the host device.
Q7. Can it be used in breakout modes?
A: Yes, it supports breakout modes such as 2×400G SR4 or 8×100G lanes, depending on host capabilities and compatible cables.
Q8. Does it support diagnostic monitoring (DDM/DOM)?
A: Yes, the module supports Digital Diagnostic Monitoring (DOM/DDM) via CMIS version 5.x, providing real-time monitoring of optical power, temperature, voltage, and module health.
Q9. What are the aggregate and per-lane data rates?
A: The total aggregate bandwidth is approximately 850Gbps, composed of eight lanes at 106.25Gbps PAM4 each, complying with 400GAUI-8 / 800GAUI-8 standards.
Q10. What is the typical power consumption?
A: The maximum power consumption ranges from 14W to 17W, depending on specific vendor implementations and operating modes.
Q11. What is the operating temperature range?
A: It operates within the commercial temperature range of 0°C to +70°C and supports storage temperatures of –40°C to +85°C.
Q12. Which standards and protocols does this module comply with?
A: It complies with IEEE 802.3db, IEEE 802.3ck, OSFP MSA v5.x, and supports InfiniBand NDR and Ethernet protocols, including CMIS v5.x management.
Q13. How can I verify compatibility with my network equipment?
A: Ensure your device supports OSFP interfaces, SR8 mode, generic optics, and has FEC enabled. Consult vendor compatibility lists from Cisco, Approved Networks, or NVIDIA.
Q14. What are typical applications for this module?
A: Commonly deployed in AI data centers, high-performance computing (HPC) clusters, high-density 800G rack interconnects, and breakout into dual 400G SR4 links or multiple 100G links.
