Watch - 5 Steps to DWDM
The amount of data accumulated today by users and enterprises requires higher network capacity and solutions for transporting 40Gb Ethernet over longer distances.

Many data centers have storage infrastructure equipped with 10GbE and 40GbE switches. Increasing the distance in these networks is challenging especially in 40GbE, as each 40GbE interface needs its own dedicated fiber between sites and 40GbE QSFP+ optics extends only up to 40 km. This requires a DWDM/OTN solution that will efficiently connect multiple 40GbE links as well as support longer distances between data centers.
PacketLight solutions for 40GbE transport include 100G/200G DWDM/OTN muxponders, and bundled 4x10GbE DWDM transponders. Both solutions are vendor-agnostic and can be integrated smoothly into any Layer-2 or Layer-3 network. In addition, the solutions provide full throughput, ultra-low latency, and low power consumption, with optional transparent Layer-1 encryption.
40Gb Ethernet Transport Solutions
PacketLight solutions for extending 40G reach:
- Muxponder Solution - muxponding 40GbE over 100G/200G DWDM network, reaching up to 2,500 km, over dark fiber or OTN infrastructure.
- Transponder Bundle Solution – transporting 40GbE over a bundle of 4x10GbE wavelengths, reaching up to 120 km.
100G/200G OTN/DWDM Muxponder Solution
PacketLight’s 100G/200G solution for metro and long haul provides configurable muxponders that enable data centers to multiplex multiple 40GbE and 10GbE interfaces over a single coherent 200G DWDM wavelength with high fiber utilization.
This solution enables the transport of multiple Ethernet protocols through QSFP+ LR4/SR4/ER4 transceivers, extending the reach of 40GbE up to 2,500 km, as seen in Figure 1.
The solution can connect to any existing third party DWDM or OTN infrastructure, and is spectrally efficient, as it carries 4x40GbE interfaces over a single wavelength.
PacketLight muxponders support Layer-1 AES-256 encryption that can be configured per 40GbE interface for securing the fiber optic link. In addition, the data is transported at full rate without reducing data throughput.
Transponder Bundle Solution
PacketLight’s unique multi-rate transponder enables the transport of 40GbE, supporting SR4, LR4 and ER4 interfaces, over eight ports, each with 10GbE SFP+ optics. By bundling 4x10GbE wavelengths, the transponder connects directly to the 40GbE QSFP+ interface on the switches, reaching up to 120 km, as seen in Figure 2.
This is achieved without the expense of upgrading the network and Layer-2/Layer-3 infrastructure to 100G.
The transponder provides low latency, low cost solution, with full performance, and optional Layer-1 encryption for the 40GbE client interface by encrypting the 4x10GbE wavelengths it uses. It also supports transport of other service types, including storage protocols 1G/2G/4G/8G/10G and 16G FC, video and SONET/SDH.
