Available Configurations

APX-OLP-1P1

A 1+1 optical line protection unit that switches the working path to a protected path on failure, with automatic, manual and forced modes and no-light lock on power loss.

Applications

🌐 Metro and Long-Haul DWDM Capacity

Builds dense wavelength layers on existing fiber using 40- and 80-channel multiplexing and adds mid-span add-drop for ring traffic.

🏢 CWDM Access and Enterprise Links

Provides 18 coarse channels over short and medium spans for access, campus and enterprise networks that value simple, passive optics.

🛡️ Optical Line Protection and Switching

Combines 1+1 line protection with high-count optical switching to guard working paths and to route light in test, monitoring and redundancy setups.

Compatibility

Interoperable with major optical transport and networking platforms. Standard channel grids, connectors and passive interfaces let these modules drop into existing DWDM, CWDM and OTN line systems.

Frequently Asked Questions

How does the APX-OLP-1P1 protect a link?

It provides 1+1 optical line protection with automatic, manual and forced switching modes, and it locks in a no-light state on power failure for predictable behaviour.
