Handheld device and method for measuring quality of optical link

A handheld device for measuring a quality of an optical link, comprising:

• an optical signal input port for receiving an optical signal;
• an optical power measurement unit for measuring a power of the optical signal;
• and
• a control unit for transmitting a measured power value of the optical signal to a mobile device, and transmitting results of quality measurement of an optical link based on interworking with the optical network terminal to the mobile device.

A method for measuring a quality of an optical link, comprising:

• measuring, by a handheld optical link quality measuring device, a power of an optical signal, via a connection to an optical link that is desired to be measured;
• measuring, by the handheld optical link quality measuring device, upstream/downstream speed and latency of the optical link, via a connection to an optical network terminal;
• and
• analyzing, by the handheld optical link quality measuring device, the upstream/downstream speed and latency of the optical link, thus determining a performance of the optical link.
