Remote Amplifier Pump


Rackable Remote Amplifier Pump unit with 3 pumps for ROPA applications.

A Remote Optical Power Amplifier (ROPA) system is an amplification system that allows for all active components in the system (i.e. all lasers/pumps) to be located at the terminal site of a WDM span, even when inline amplification is necessary. Utilizing the EKINOPS RM RAP in conjunction with the rest of the EKINOPS amplifier family allows for DWDM links of up to 450 km with no inlineactive components.

RM RAP used to Pump a Passive Device

The ROPA system consists of two components, the EKINOPS RM RAP (Remote Amplifier Pump) and a “remote passive device”, the EKINOPS CM ROA (Remote Optical Amplifier), which is spliced into the fiber within 80 km of the location of the EKINOPS RM RAP. The EKINOPS RM RAP remotelypumps the CM ROA, amplifying the WDM channels that pass through it. The EKINOPS RM RAP hasthree pump laser diodes and features multiple independent laser safety features based on Automatic Power Reduction (APR). The EKINOPS RM RAP contains redundant, replaceable powersupplies and fan units.

The EKINOPS CM ROA is purely passive, thus eliminating the need for local power, environmental control, and maintenance as would be required if a conventional amplifier was used instead.The EKINOPS CM ROA can be housed in an independent splice box or can be installed in anexisting splice box on the route.

  • Reduced Capital Expenses:
    • Traverses extremely long distances without any inline active devices/amplifiers (ex: up to 450 km with no inline amplifiers for 10G)
    • Eliminates the need for costly environmentally controlled enclosure required to house activecomponents
  • Lower Operational Expenses:
    • Minimize the number of truckrolls/site visits
    • Automatic Power Shut Down for safety
    • Robust Monitoring Capabilitiesfor proactive management
  • Carrier Class Redundancy(power supplies, fans)

The ROPA system is ideal for any application that requires traversing large distances withoutthe use of inline amplifiers. Traditional applications that fall into this category include distanceextension, “hut” skipping (skipping environmental huts, or enclosures, on WDM routes) and submarine.

In the above diagram, because there are no active components on the WDM span, there is noneed for environmental enclosure (ex. : hut) along its entire length allowing for a single hopdistance of up to 450 km. This is ideal for deploying in locations where real estate is expensive or does not exist. In general, long distances with no inline enclosures saves operational cost sassociated with maintaining the enclosures. The ability to go very long distances without active components is also ideal for submarine applications.

Finally, the ROPA configuration can be utilized simply to achieve longer distances (i.e. distance extension) or to achieve longer distances between amplifier sites for WDM spans up to 450 km. This allows the service provider to extend its service reach and address more business customers.
