EKINOPS360 PLATFORM

PM ORA14

Pluggable Raman Amplification Module

PM ORA14

Pluggable Raman amplifier with +14 dB gain. Can be used in counter-propogating or co-propogating configurations.

The EKINOPS PM ORA14, part of the EKINOPS 360 platform, uses enhanced Raman amplification to extend the span reach of optical DWDM networks. In addition, the PM ORA14 also improves OSNR (Optical Signal to Noise Ratio).

The EKINOPS PM ORA14 offers a maximum output power of 28.5 dBm.

The amplifier includes an automatic eye safety mechanism that shuts down the amplifier or reduces the power within class 1M in case of fiber link interruption. This comprehensive safety mechanism is extremely important due to the Raman amplifiers’ high output power.

It is a 1 slot large Pluggable Module (PM).

As shown in Figure 1, the PM ORA14 is well suited for RAMAN Amplification for Long Distance (“hut skipping”) and Submarine Transport for applications.

Finally, the PM ORA14 is also adapted to multi-hop transmissions (Figure 2) where the RAMAN amplification improves the overall OSNR. This enables for instance technology disruptive steps such as passing from 10G to 100G, or even from 100Gbps to 200Gbps line rates which rely on higher order modulation formats. Since the latter are more sensitive to the accumulated noise, their usage would not be possible when solely relying on EDFA amplification.

Management

The EKINOPS PM ORA14 module can be managed through SNMP or via the EKINOPS standard element level management interfaces, which include a Command Line Interface (CLI) and an EKINOPS java-based Graphical User Interface (GUI). The CLI is accessible via Secure Socket Shell (SSH) and Telnet remotely or via a local serial port locally on the management board.

Complete performance monitoring and management are provided, including laser shut offand local and remote loopback, useful for maintenance and fault isolation.

The EKINOPS PM ORA14 module is also supported by Celestis NMS, the EKINOPS advanced Network Management System.
