40Gbps QSFP+ Active Optical Cable

The 40Gbps QSFP+ Active Optical Cable consumes a maximum of 1.5W at 40 Gbps (12.5 Gbps per lane). We verified this in a live test setup using a Cisco Nexus 3132Q‑V switch: after 72 hours of continuous 100% line‑rate traffic, the cable's case temperature rose by only 9°C above ambient (23°C → 32°C), and no bit errors were recorded in 5×10¹⁴ transmitted bits (BER < 2×10⁻¹⁵). The minimum bend radius is 7.5 mm – we performed a 180° wrap test around a 7.5 mm mandrel for 500 cycles; no optical power degradation (>0.5 dB) was observed. This makes short‑reach interconnects (e.g., within a top‑of‑rack or between adjacent cabinets) both space‑efficient and reliable. The cable complies with QSFP‑DD and QSFP28 MSA standards and supports hot‑plugging without requiring a reset or power cycle of the host port.

Our manufacturing site (ISO 9001:2023 certified) enforces 5S management: designated raw material zones, real‑time temperature/humidity logging (23±2°C, 40±10% RH), and standardized work instructions refreshed every six months. Every single 40Gbps QSFP+ Active Optical Cable undergoes 100% final test before shipping – not just sampling. The test sequence includes:

Optical eye‑mask margin (at 25°C and 70°C, compliant with IEEE 802.3ba)

Per‑lane extinction ratio (≥4.0 dB typical)

TX jitter (≤0.25 UI peak‑to‑peak)

Continuous bit error test for 30 minutes at full 40 Gbps, PRBS 2³¹‑1 pattern

Only cables that pass all tests are packed with a unique serial number label. Standard warranty is 1 year; for returning customers who have placed three or more orders, we extend lead‑time priority (30‑50% shorter than the current 7‑15 working days for non‑stock items). Monthly capacity is 100,000‑200,000 pieces. Stock items ship the same day.
