 Advantages of Tunable SFP+

The tunable SFP+ transceiver is an important transceiver module for next generation enterprise, metro and regional optical network equipment continuing the replacement of fixed-wavelength modules and of non-pluggable ports. This form factor allows network equipment manufacturers to reduce the size and power consumption for 10G connections while supporting the network operators rapidly increasing capacity needs driven by data-heavy network applications. Also, it will allow form-factor commonality between client- and line-side, offering greater flexibility in equipment configurations.

  • Flexible network management. A tunable SFP+ transceiver will be remotely configured for a specific wavelength to support bandwidth changes as needed in Enterprise or Metro networks.
  • Reduced network inventory. One tunable SFP+ transceiver will support more than 80 different wavelengths. It will allow network operators to hold one tunable device code as opposed to 80+ fixed wavelength transceivers.
  • Reduced power consumption. It will provide a significant reduction in electrical power dissipation compared to other tunable solutions.
  • Compact and high-density form factor. The new tunable SFP+ transceiver will be about the size of a pack of gum, saving valuable real estate in data centers.
  • Increased network capacity. The tunable SFP+ will double the number of channels supported in this compact transceiver form factor. Upgrading to 50GHz channel spacing doubles the capacity potential in Enterprise and Metro networks.
