Frequently Questions and Answers

Q1. What is a QSFP112‑400G‑DR4 module?

A: The QSFP112‑400G‑DR4 is a QSFP112-form-factor transceiver supporting 400 Gbps Ethernet over single-mode fiber (SMF) using four parallel PAM4 lanes at ~1310 nm, compliant with IEEE 802.3 and QSFP112 MSA standards.

Q2. What is the maximum supported reach?

A: Supports up to 500 meters over G.652 SMF, provided host-side forward error correction (FEC) like KP4 is enabled.

Q3. What fiber type and connector does it use?

A: Uses MPO‑12 APC connector over single‑mode 9/125 µm fiber (G.652).

Q4. Is QSFP112‑400G‑DR4 compatible with equipment from different vendors?

A: Yes. It is MSA-compliant, works with Cisco, ProLabs, FS.com, AsterFusion, Coherent, and others supporting generic QSFP112 optics.

Q5. Does the module support hot‑swapping?

A: Yes, it is hot-pluggable, allowing insertion or removal without powering down the host device.

Q6. Can it operate in breakout modes?

A: Yes—supports 4×100G DR1 or 2×200G DR2 breakout modes via host support and compatible cabling.

Q7. Does it include diagnostic monitoring (DDM/DOM)?

A: Yes—supports Digital Optical Monitoring (DOM/DDM) and CMIS (v5.0) diagnostics reporting temperature, voltage, and optical power via I²C.

Q8. What is the aggregate and per-lane rate?

A: The electrical/optical interface supports ~425 Gbps aggregate, using four 106.25 Gbps PAM4 lanes (~53.125 GBd per lane) under 400GAUI‑4.

Q9. What is the typical power consumption?

A: Up to 10 W maximum, with many implementations under 8 W depending on vendor and models.

Q10. What is the operating temperature range?

A: Typical case temperature range: 0 °C to 70 °C (commercial grade).

Q11. What standards and protocols apply?

A: Compliant with IEEE 802.3bs / 802.3cu (400GBASE-DR4), QSFP112 MSA, CMIS v5.0, and 400GAUI‑4 signaling per IEEE 802.3ck/km.

Q12. How to check compatibility with my device?

A: Confirm your host or switch supports QSFP112 ports, allows third-party optics, and enables FEC. Generic modules tested on >100 platforms have serialized compatibility lists.

Q13. What are typical use cases?

A: Ideal for 400 GbE data center interconnect, HPC/AI compute clusters, spine-leaf links, or breakout into 100G/200G lanes within 500 m SMF span.

Q14. What are the per‑lane transmitter/receiver specifications?

A: Typical transmit power: –2.9 dBm (min) to +4.0 dBm (max); receiver sensitivity: around –5.9 dBm. Max insertion loss: ~3 dB per lane for 500 m link margin.

Q15. Are industrial or extended‑temperature variants available?

A: Primarily provided in commercial grade. Extended or industrial versions are rare in QSFP112 form factor but may be available upon request
