Q1. What is an OSFP‑400G‑DR4 Finned Top module?
A: The OSFP‑400G‑DR4 Finned Top is an OSFP form-factor transceiver supporting 400 Gbps Ethernet over single-mode fiber (SMF) using PAM4-modulated 4×1310 nm lanes, with an MPO‑12/APC connector and integrated heat-dissipating fins on top for enhanced cooling.
Q2. What is the maximum reach of this module?
A: Supports up to 500 m over G.652 single-mode fiber, provided host-side FEC (e.g. KP4) is enabled.
Q3. Which connector and fiber type does it use?
A: Utilizes an MPO‑12/APC connector over single-mode 9/125 µm fiber.
Q4. Is it compatible with different vendor equipment?
A: Yes. It is OSFP MSA and IEEE 802.3bs/ck compliant, and interoperable with OSFP-enabled equipment from Cisco, Arista, ProLabs, Flexoptix, FS.com, etc., where third-party optics are allowed.
Q5. Does the module support hot‑swapping?
A: Yes—fully hot-pluggable, enabling insertion and removal without powering down the system.
Q6. Can it be used in breakout mode?
A: Yes—supports 4×100G DR1 breakout via appropriate fiber splitters/cables, splitting to four 100G DR optics when host supports lane disabling.
Q7. Does it support diagnostic monitoring (DDM/DOM)?
A: Yes. Supports digital diagnostic monitoring via CMIS 4.0 / OSFP MSA, reporting lane power, temperature, voltage, and status over I²C.
Q8. What is the aggregate and per-lane data rate?
A: Operates at ~425 Gbps aggregate (4×106.25 Gbps PAM4 optical lanes and 8×53.125 Gbps PAM4 over electrical interface).
Q9. What is typical power consumption?
A: Up to 9–10 W (max ~12 W) in 400G mode; drops to ~5 W when running in dual‑channel (200G) mode.
Q10. What is the supported operating temperature range?
A: Designed for 0 °C to 70 °C case temperature in standard modules. Storage temperature and extended variants may differ.
Q11. What standards does it comply with?
A: Complies with IEEE 802.3bs (400GBASE‑DR4), IEEE 802.3ck, OSFP MSA, CMIS V4.0, 400GAUI‑8, CEI‑56G‑VSR‑PAM4 etc.
Q12. How to verify compatibility with my network device?
A: Ensure your switch/NIC supports OSFP optics, host-side FEC, and permits third-party optics. Confirm part numbers or compatibility lists for “OSFP-400G-DR4 Finned Top.”
Q13. What applications is this module suited for?
A: Ideal for data center interconnect, spine-leaf or switch-to-switch links over SMF up to 500 m, and seamless breakout to 100G DR deployments. Commonly used in platforms requiring efficient heat dissipation.
Q14. What is the optical power budget per lane?
A: Typical transmit power: –2.9 to +4.0 dBm; receiver sensitivity: about –4.4 dBm, providing ~1.5 dB margin over 500 m SMF with KP4 FEC.
Q15. Are there industrial or extended-temperature versions available?
A: Primarily offered in commercial spec (0–70 °C). Industrial or extended-temperature finned‑top variants may be available from select vendors but are less common.
