High Capacity Next Generation Optical Amplifier


A next-generation pluggable EDFA-based variable gain inline amplifier with mid-stage access for chromatic dispersion compensation and up to 23dBm output power and integrated OSC that  automatically compensates the gain settings to compensate for power fluctuations due to channel add/drop and fiber aging

Carrier networks continue to grow, with Service Level Agreements becoming ever more demanding. As networks grow, so does the need for efficient optical amplification. EKINOPS continues to lead the way in optical performance and amplification with the new EKINOPS HCS amplifier family. It allows optical signals to be transmitted over longer distances without the need for regeneration or external power control modules. The EKINOPS HCS amplifier family automatically compensates the gain settings as fibers degrade over time due to aging or splicing, and seamlessly adjusts the optical power as channels are added and removed. This eliminates the need to manually adjust the network as it evolves. The EKINOPS HCS amplifier family relies on EDFAs (Erbium Doped Fiber Amplifiers) which are protocol and data-rate independent and can be used in 10G, 40G, 100G networks and beyond.

The EKINOPS HCS amplifier family amplifies optical signals bidirectionally and can be ordered as integrated Optical Boost and Pre-amp (OABP) or Integrated Optical In-Line Amplifier (OAIL) in a single unit form factor. As a booster, the PM OA-HCS amplifies the outgoing DWDM signals from the transmit side to overcome the attenuation of the fiber span. As a preamplifier, the PM OABP-HCS amplifies the DWDM signals coming into the receiver in order to allow a sufficient optical power level for the receiver of each wavelength. The EKINOPS PM OAIL-HCS when used for bidirectional inline amplification offers a mid-stage access for Chromatic Dispersion devices. Both options provide up to 23dBm per channel optical gain while requiring minimal power. The EKINOPS HCS amplifier family also integrates an Optical Supervisory Channel to provide the most features in the best in class footprint and at the best possible price point.

The implemented span loss monitoring functionality deals efficiently with fiber aging and fiber fixes-related issues, avoiding OSNR impact on any channels.

Furthermore, when operating in constant gain mode, a channel count modification at the amplifier’s input (channel drops or adds) is successfully handled by the span insertion loss monitoring functionality. This allows it to cope with fast transients by maintaining the channels’ powers constant, so the stability of the optical system layer is warranted.

EKINOPS amplifiers are unique in the industry in that they can be upgraded in service in the field. The EKINOPS solution distributes the cost of the amplifier over time as the customer gains economic benefit from the network. It is truly a pay as you grow transport solution.


At the element level, the EKINOPS PM OA-HCS family of modules can be managed through SNMP or via the EKINOPS standard element level management interfaces. These include a CLI (Command Line Interface) and an EKINOPS java-based GUI (Graphical User Interface). The CLI is accessible via SSH and Telnet remotely or via a serial port locally. Complete performance monitoring and management is provided, including laser shutdown status, amplifier configuration parameters, input power, and output power. The EKINOPS HCS amplifier family is of course supported by the EKINOPS SNMP Element Manager and the EKINOPS Multi-Protocol Service and Network Manager.
