Description

SC‑SC mode conditioning patch cord designed to run 1000BASE‑LX optics over legacy 62.5/125 µm multimode fiber by introducing an offset launch to mitigate differential mode delay. Ideal for campus and data center links transitioning from MMF to LX optics.

Features

- Enables LX optics on legacy multimode runs
- Reduces differential mode delay and link errors
- SC duplex connectors for quick deployment
- Cost-effective migration path without re-cabling

FAQs

Q: When do I need a mode conditioning patch cord?
A: Use it when running 1000BASE‑LX optics over legacy 62.5/125 µm multimode to avoid modal dispersion and link instability.

Q: Can this be used with SX optics?
A: No. MCPs are intended for LX/LH (1310 nm) optics, not SX (850 nm).

Q: Does it work with 50/125 µm OM2 fiber?
A: It can be used if recommended by your optics vendor, but MCPs are primarily required for 62.5/125 µm OM1 installations.
