Frequently Asked Questions
- Is the Huawei QSFP‑40G‑CU1M High‑Speed Direct‑Attach Cabl compatible with my switch or firewall?
- SFP transceivers follow industry standards (1000BASE-SX, 1000BASE-LX, 10GBASE-SR, etc.). Most switches and firewalls accept standard-compliant SFPs regardless of brand. Contact Da3m to confirm compatibility with your specific device.
- What fiber type does the Huawei QSFP‑40G‑CU1M High‑Speed Direct‑Attach Cabl require?
- Refer to the specifications: SX modules require multimode fiber (OM3/OM4); LX/LR modules work with single-mode fiber for longer distances. Da3m stocks both multimode and single-mode fiber patch cords.
- What is the maximum distance supported?
- See the specifications table above. Multimode SFP modules typically support up to 300–550m; single-mode LX/LR modules support up to 10km or more depending on the variant.
