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.
