RETN Capacity service offers two types of leased channels

1. WAVELENGTHS based on the latest generation DWDM technology

RETN WL («wavelength») – a fixed, non-switchable point-to-point DWDM wavelength with constant bandwidth between two fixed points over RETN’s fiber network.

RETN WLP (protected wavelength) – is a fixed, non-routed, point-to-point channel with constant bandwidth and automated protection via geographically diverse routes.

Customers can choose an unprotected service, or take advantage of protected solutions to ensure higher availability of their traffic delivery between fixed points.

For both services wavelength connectivity runs on dedicated fiber and optical equipment.

Capacity service based on DWDM technology is offered at different speeds and supports multiple interface types:

Wavelengths Speed
1GbE 1 Gbps
10GbE LAN PHY / WAN PHY nx10 Gbps
100GbE 100 Gbps

2. PRIVATE LINE SERVICE based on SDH/SONET technology:

RETN PLS (private line service) – is a service of leasing a fixed, non-routed, point-to-point channel with constant bandwidth using SDH/SONET technology.

The service is provided over RETN’s optical and electrical interfaces at following speeds:

Private Line Speed
SONET OC-3 SDH STM-1 155Mbps
SONET OC-12 SDH STM-4 622 Mbps
SONET OC-48 SDH STM-16 2.5Gbps
SONET OC-192 SDH STM-64 10 Gbps
SONET OC-768 SDH STM-256 40 Gbps

Dark Fibre Lease

By leasing dark fibre and providing last miles across RETN’s transboundary network and metro-networks, we offer a cost-effective service to enable you to scale you network demands and business needs.

The service is available in selected regions. For more information, please contact us at or check with your Account Representative at RETN.

RETN Capacity and Dark Fibre Lease services utilise a guaranteed SLA and 24×7 technical support.
