Replacement & Compatibility FAQ
Q: Is the OC-LK-2MBD still in production?
A: Phoenix Contact periodically updates its product portfolio. Contact us or Phoenix Contact directly to confirm current production status.
Q: Can I use a third-party fiber optic module as a direct replacement?
A: Possibly, but you must verify data rate, fiber type, connector type, supply voltage, and protocol compatibility. We recommend testing in a non-production environment first.
Q: What is the difference between OC-LK-2MBD and OC-LK-1MBD?
A: The primary difference is the maximum transmission rate: 2 Mbit/s vs. 1 Mbit/s. Choose based on your network’s bandwidth requirements.
Q: Do you offer technical support for integration?
A: Yes. Our engineering team can assist with compatibility assessment and integration guidance. Contact [email protected].
