FAQs

Q: Does the adapter add or change link features like FEC or reach?
A: No. It is a transparent adapter; link features are determined by the host platform and the inserted CPAK optic.

Q: Which CPAK modules are intended for this adapter?
A: 4x25G-lane CPAK 100G modules (for example, LR4-class). Check platform release notes for specific supported optics.

Q: Is special configuration required?
A: Typically no. If the platform supports the combination, it will recognize the inserted CPAK optic via the adapter.

Q: Can I use 10x10G CPAK optics with this adapter?
A: No. Use the dedicated 10x10G-compatible variant for 10-lane CPAK modules.
