1. Confirm the link conditions first.
The Axonode 400GBASE-DR4 QSFP-DD 500m optical transceiver supports 400GbE links over parallel single-mode fiber. Confirm the MPO-12 APC cabling, host FEC, port compatibility and total optical loss before deployment.
400G QSFP-DD Port
Confirm that the host device supports a 400G QSFP-DD port and the required compatibility coding.
MPO-12 APC / SMF
Use the specified parallel single-mode fiber interface and verify polarity before connection.
Reach Up to 500m
Verify route loss, connector loss and engineering margin before deployment.

3. Data-center deployment
Use this module for parallel single-mode links between compatible 400G QSFP-DD ports. Confirm MPO polarity, APC connector condition, host FEC and the end-to-end optical budget before installation.
4. Compatibility prepared for your network
Confirm the exact device, port mode, software or firmware, coding profile and monitoring requirements. QSFP-DD form factor alone does not guarantee host acceptance.
5. Testing and deployment checks
Project checks can include host recognition, FEC status, transmit and receive levels, lane health, connector inspection and link establishment according to the target platform.
Frequently Asked Questions
i. What fiber and connector does this module require?
It uses parallel single-mode fiber with an MPO-12 APC connector.
ii. Is the maximum reach 500m?
The specified reach is up to 500m. Actual deployment depends on fiber loss, connector condition and engineering margin.
iii. How many optical lanes are used?
The optical interface uses four 106.25Gbps PAM4 lanes.
iv. Is host FEC required?
Yes. The verified product knowledge specifies host forward error correction as required.
v. Can an MPO-12 UPC cable be used?
No substitution should be assumed. Use the specified MPO-12 APC interface and confirm the patching arrangement before deployment.
vi. Is compatibility universal?
No. Coding, port mode, firmware, FEC and host requirements must be checked for the target device.
vii. What should be checked before installation?
Confirm MPO polarity, connector cleanliness, APC interface type, host FEC, coding and the end-to-end loss budget.
viii. What operating temperature is verified?
The verified commercial operating range is 0 to +70 degrees C.
