Celebrating 100,000 Smart SFPs
Celebrating 100,000 Smart SFPs


May 26, 2022, Hilversum, The Netherlands – International telecommunications design services company AimValley, today announces that it built 100,000 Smart SFPs. This milestone enables over 2.1 million TDM circuit emulation pseudowires in telecom networks worldwide.

Just over 10 Years ago, OE Solutions and AimValley jointly conceived the Smart SFP idea and started to build a comprehensive and feature-rich Smart SFP portfolio. The idea was built upon the strengths of both companies, by joining transceiver technology with systems and network technology. A match made in technology heaven!

Smart SFPs are deployed in networks for major 5G mobile operators, communications service providers, as well as mission-critical networks for Utility, Transport, Oil & Gas, Government, and Energy.

Smart SFP Technology

While ‘regular’ transceivers perform Electrical/Optical and O/E conversion, Smart SFPs integrate additional network functions inside the transceiver. These functions range from Layer2/Layer3 OAM (line monitoring) to TDM circuit emulation over Ethernet and IP/MPLS networks.

The Smart SFPs meet carrier-class requirements such as -40ºC/+85ºC case operating temperature for operating in harsh conditions and remote locations.

To enable the integration of Very Large Scale Integration (VLSI) semiconductor chips inside the very limited space of the MSA industry-standard SFP form factor, bare die and wire bonding techniques have been applied. Next to this, significant VLSI capacity and a robust Real-Time Operating System (RTOS) are added to the devices. The low Smart SFP power consumption is achieved by AimValley’s patented power reduction technology and allows for operation -40ºC/+85ºC environments.

Smart SFP Deployment

Smart SFPs are utilized on a large range of telecommunication network equipment, such as:


Over the past 10 years, the circuit emulation Smart SFP portfolio has grown to support solutions for ANSI and ETSI markets for all TDM rates:

The complete portfolio is available as a Plug & Play solution. Using the Smart SFP technology, customer-specific options can be provided.


Future Products

While the Smart SFP portfolio is already very comprehensive, it is by far from complete.
At AimValley we are currently working on a variety of future products. Just to name a few:

  • The Ethernet over SONET/SDH Smart SFP. This Smart SFP plugs into a 10GE router port and tunnels the 10GE signal over an OC-48/STM-16 transport network, similar to a 10G over SONET/SDH POS card. A solution to enable the opposite: “Packet over TDM”.
  • A solution to resolve the business-specific legacy interfaces of the verticals
  • A custom DPI solution in an SPF form factor
  • SD-WAN ML-PPP/HDLC Enterprise/Business Access

The common theme, is the requirement to offload the new hardware with the legacy services, while still maintaining support of the required solutions for the end customer.

If you can imagine it - we likely have a solution for it - or we can build one for you!
