Long Haul 100G DWDM Network with Low Latency

Building a low latency network from London to Moscow

At a Glance

Company: Avelacom
Location: Latvia
Industry: Carrier, Internet Service Provider

Challenge: To build a new segment of low latency DWDM network between London and Moscow, which mainly serves the financial market.

Solution: PacketLight’s optical amplifier and the 100G muxponder/transponder were selected to build the 1,100 km network.

Success: The solution met the required low latency goals, and provided redundancy and full remote monitoring and line protection.

Background

Avelacom, one of the fastest growing international telecom/IT companies in Europe, was looking to complete a new segment of DWDM network between London and Moscow, one of its flagship routes. This link was mainly used for providing services to capital market companies looking for low latency connectivity.

The Challenge

The challenge was to design the lowest latency route possible for the financial enterprises on the London-Moscow route.

"PacketLight’s products allowed us to extend our network as well as to achieve the project low latency goals."

The Solution

Avelacom selected PacketLight’s optical transport solutions, and leveraged its hardware to build the 1,100 km high-speed network, while meeting the stringent requirements expected by financial sectors to reduce network latency.

PacketLight’s PL-1000GT 100G Muxponder/Transponder for long haul and the PL‑1000IL Optical Amplifier were selected for the task. The carrier grade solution provided the necessary throughput rate of 100G in a compact, easy-to-configure 1U solution, with full optical transport network (OTN) integration, and remote management and troubleshooting capabilities.

The solution enabled Avelacom to meet the aggressive demands of a 100G low latency DWDM long haul network with full add/drop capabilities at all major sites.

Success

PacketLight successfully extended the network and met the project’s low latency goals. Avelacom has always had a round-trip delay of 37.1 milliseconds. PacketLight’s upgrade reduced this by up to two milliseconds, achieving under 35 millisecond latency round-trip delay in the London to Moscow route. The solution also provided the required redundancy with full remote monitoring, a dedicated optical supervisory channel (OSC) and line protection capabilities. 

Aleksey Larichev, Managing Director of Avelacom: “PacketLight’s products allowed us to extend our network as well as to achieve the project low latency goals. By opting for PacketLight Networks we could cut up to 30% of equipment’s latency. The solution also provided the required redundancy with full remote monitoring, a dedicated optical supervisory channel (OSC) and possibility of line protection”.
