Q1. What is an OSFP‑800G‑DR8 Finned Top module?
A: The OSFP‑800G‑DR8 Finned Top is a high-density OSFP transceiver supporting 800 Gbps Ethernet over single-mode fiber (SMF), featuring eight parallel PAM4 lanes at 1310 nm using dual MPO‑12/APC connectors. The “Finned Top” housing provides enhanced heat dissipation via thermal fins.
Q2. What does “DR8” signify in this model?
A: DR8 denotes “Digital Reach, 8‑lane” architecture—operating as two independent 400GBASE‑DR4 data streams over SMF using 8 lanes of 106.25 Gbps PAM4 each.
Q3. What is the maximum supported transmission distance?
A: Supports up to 500 meters over G.652 single‑mode fiber, assuming host-side FEC (e.g. KP4) is enabled.
Q4. What connector and fiber type does it use?
A: Uses dual MPO‑12 APC connectors over 9/125 µm single-mode fiber (SMF).
Q5. Is this module compatible with different brand equipment?
A: Yes—it's OSFP MSA-compliant, works with vendors like Coherent, Gigalight, FS.com, YXFiber, ProLabs, and others supporting generic OSFP optics.
Q6. Does the module support hot-swapping?
A: Yes, OSFP form factor supports hot-pluggable insertion/removal without powering down.
Q7. Can it operate in breakout modes?
A: Yes—it supports 2×400GBASE‑DR4 breakout mode, splitting into two independent 400 G links over DR4 lanes, depending on host support.
Q8. Does it support digital diagnostics (DDM/DOM)?
A: Yes—it implements CMIS 5.0 (or similar) via I²C for monitoring temperature, voltage, optical power, and module status.
Q9. What is the aggregate and per-lane data rate?
A: Aggregates up to ≈850 Gbps optical (two 400Gb links combined); per lane rate is 53.125 GBd PAM4 (106.25 Gb/s) across 8 lanes. Corresponds to IEEE 400GAUI‑4 / 800GAUI‐8 electrical interfaces.
Q10. What is the typical power consumption?
A: Maximum power dissipation is ≈16 W, depending on vendor and mode.
Q11. What operating temperature range is supported?
A: Commercial operating case temperature is 0 °C to 70 °C, with storage range –40 °C to +85 °C.
Q12. Which standards does it comply with?
A: Compliant with IEEE 802.3bs, IEEE 802.3cu, IEEE 802.3ck, OSFP MSA Rev 5.0, and CMIS v5.x, supporting 800GBASE‑DR8 and dual‑400G breakout modes.
Q13. How to verify compatibility with my device?
A: Ensure your switch or NIC supports OSFP ports, DR8 breakout mode or 800G single-port DR8 configuration, allows generic optics, and has FEC enabled. Many vendors publish compatibility lists.
Q14. What are typical applications for this module?
A: Suitable for dual‑port 400G data center links, high-speed spine-leaf interconnects, cloud and HPC backbones, or dual‑400G host connectivity over SMF up to 500 m.
Q15. What are the transmitter/receiver optical specs per lane?
A: Typical launch power: –2.9 to +4.0 dBm per lane; receiver sensitivity ~–5.9 dBm (OMAouter); TDECQ ≤ 3.4 dB, SECQ ~3.4 dB—suitable margin for 500 m.
Q16. Are industrial or extended-temperature variants available?
A: Currently primarily available in commercial-grade (0–70 °C). Some vendors may offer extended/special versions upon request.
