The Optical Transport Network (OTN) defined in ITU-T G.709 is the default networking protocol that underpins today’s metro, regional and long-haul Dense Wavelength Division Multiplexing (DWDM) packet-optical transport networks. Two generations of OTN have already been widely deployed: OTN 1.0, which was based on 10G WDM transport; and OTN 2.0, which enabled the transition to Coherent 100G Metro OTN switched networks and is the de facto standard in transport networks today. OTN has proven to be extremely flexible for accommodating new client signals and line rates. It offers the highest network reliability, providing 50 ms protection against any number of failures and deterministic service isolation capable of supporting the strictest Service Level Agreements (SLAs).
A transition to next-generation OTN is needed to scale the optical transport infrastructure to meet the unprecedented growth in bandwidth requirements. OTN 3.0 introduces flexible, “beyond 100G” (B100G) optical transport capabilities, coupled with support for new services like 25GbE, 50GbE, 200GbE, 400GbE and Flexible Ethernet. While there will be an enduring market need for OTN 2.0, packet optical transport networks will require OTN 3.0 to address another wave of growth in network traffic.
Our OTN processors and OTN physical layers (PHYs) offer leading innovation, integration and power for Data Center Interconnect (DCI) networks. They deliver the quickest time to market and lowest R&D expense for the OEM and minimize the total cost of ownership for the service provider.
We also offer a comprehensive portfolio of optical networking solutions for Synchronous Optical Networking/Synchronous Digital Hierarchy (SONET/SDH), T1/E1 and Fiber-to-the-Home/Passive Optical Network (FTTH/PON) protocols.
Multi-Service OTN Processors
Our portfolio of the industry's most integrated OTN processors features our award-winning DIGI family of devices. These OTN processors deliver optimized power and footprints that uniquely address the requirements of DWDM transponders and muxponders, switchponders, OTN switching platforms, DCI and OTN mobile fronthaul architectures.
Key Features:
- Support for 10GE, 25GE, 50GE, 100GE, 200GE, 400GE, FlexE and FlexO interfaces
- Low per-port power consumption
- Flexible high-performing SerDes up to 56G PAM-4
- Glueless interfacing to OTN switches, Ethernet switches, packet processors and cross-connects
OTN PHYs
To extend OTN to the router, our multi-rate OTN PHYs enable a single management layer between optical transport and routing networks, resulting in lower operating costs and improved service availability for network operators.
Key Features:
- Tri-Mode FEC at 10G and 40G OTN rates
- Enable universal OTN/Ethernet router ports
- Ultra-low latency OTN encryption for secure cloud connectivity
- Low per-port power consumption
- Enable router line card capacities of 1 Tbps and higher

Microchip and Acacia Collaborate to Enable Transition to 400G Pluggable Coherent Optics
Bandwidth growth, driven by the expansion of data centers and 5G network build-outs, is expected to drive the need for faster coherent Dense Wavelength Division Multiplexing (DWDM) pluggable optics. Consequently, Data Center Interconnect (DCI) and metro Optical Transport Network (OTN) platforms are transitioning from 100/200G to 400G pluggable coherent optical modules to support these hyper-connected architectures.
We are supporting the transition to 400G interconnect rates by bringing to market interoperable solution sets consisting of our DIGI-G5 OTN processor and META-DX1 terabit secured-Ethernet PHY and Acacia’s 400G pluggable coherent optics.
