Today, when optical transceivers are plugged into ports of network equipment and a user administratively shuts down a specific port, the network equipment does not remove the power from the optical transceivers and, instead, only the laser is shut down. When the user shuts the individual port with optical transceiver, the power consumption of the optical transceiver will be marginally reduced, however significant power is still consumed. Techniques described herein provide for switching products that are always ready, not always on. Techniques described herein provide for ports that are always ready to be powered up but are powered down when not in use to save power.
