Compatible Replacement & Equivalent Models
When the OCX-CTN-13-R-D-ST-ACV is discontinued, on extended lead time, or outside budget, the following models may serve as functional equivalents — always verify electrical and mechanical compatibility before substitution:
- PHOENIX DIGITAL OCX-CTN-85-R-D-ST-ACV — 850 nm variant; suitable for shorter multimode runs
- PHOENIX DIGITAL OCX-CTN-13-R-D-SC-ACV — SC connector variant; same wavelength, different connector
- Moxa IMC-101-S-SC — Industrial fiber media converter; verify protocol compatibility
- Advantech EKI-2541SI — Industrial fiber optic module; confirm pinout and signal levels
- Hirschmann OZD Profi — PROFIBUS fiber optic repeater; application-specific match required
⚠ Always consult the original datasheet and system integrator before substituting optical modules. Wavelength, connector type, and signal protocol must match exactly.

Selection Guide
Use the following criteria to confirm the OCX-CTN-13-R-D-ST-ACV is the correct module for your application:
- ✅ Wavelength: Your fiber link requires 1300 nm operation
- ✅ Connector: Your fiber patch cables use ST connectors
- ✅ Direction: Full-duplex (R-D) communication is required
- ✅ Signal: ACV-compatible input/output signal levels
- ✅ Distance: Link budget supports 1300 nm multimode (up to ~2 km typical)
- ✅ Environment: Industrial temperature range and DIN rail mounting required
If any criterion does not match, refer to the Compatible Replacement section above or contact our technical team for a cross-reference.

Replacement & Compatibility FAQ
Q: Can I replace OCX-CTN-13-R-D-ST-ACV with an 850 nm module?
A: Only if your fiber link distance is under 500 m and your fiber type supports 850 nm. The 1300 nm variant offers significantly lower attenuation for longer runs.
Q: Is the SC connector version a drop-in replacement?
A: Electrically yes, but you will need ST-to-SC fiber adapter cables or patch cord changes. Confirm with your fiber plant manager.
Q: Does this module support PROFINET?
A: The OCX-CTN series is primarily designed for PROFIBUS and serial-over-fiber protocols. For PROFINET fiber, consider PHOENIX CONTACT FL SWITCH or similar managed switch solutions.
Q: What is the maximum fiber distance for this module?
A: Typically up to 2 km on 62.5/125 µm multimode fiber at 1300 nm. Actual distance depends on fiber quality, connector losses, and data rate — consult the link budget calculation in the datasheet.
Q: Is this product RoHS compliant?
A: PHOENIX DIGITAL products in this series are generally RoHS compliant. Confirm with the current product datasheet or contact us for the declaration of conformity.
Q: Can Konmask.com provide a certificate of conformity?
A: Yes. CoC and supplier documentation are available upon request for quality-audited procurement.
