Abstract
The present application relates to a first optical network node (400, 700, 800) that comprises: a first optical add-drop multiplexer, OADM (410) coupled to a first optical fibre (401); a transceiver (420) comprising a receiver (422) and a transmitter (424); and an optical configuration unit (430) 5 coupled between the transceiver (420) and the first OADM (410), wherein the optical configuration unit (430) is operable to selectively couple the receiver (422) to the first OADM (410) so as to receive a first optical signal dropped from the first optical fibre (401) or to selectively couple the transmitter (424) to the first OADM (410) so as to add a second optical signal to the first optical fibre (401).

1-35. (canceled)
A first optical network node comprising:
- a first optical add-drop multiplexer (OADM) coupled to a first optical fiber;
- a transceiver comprising a receiver and a transmitter;
- and
- an optical configuration unit coupled between the transceiver and the first OADM, wherein the optical configuration unit is operable to selectively couple the receiver to the first OADM so as to receive a first optical signal dropped from the first optical fiber or to selectively couple the transmitter to the first OADM so as to add a second optical signal to the first optical fiber.
An optical network comprising:
- a plurality of optical network nodes;
- and
- a first optical fiber coupled to each of the plurality of optical network nodes;
- wherein each of the plurality of optical network nodes comprises:
- a first optical add-drop multiplexer (OADM) coupled to the first optical fiber;
- a transceiver comprising a receiver and a transmitter;
- and
- an optical configuration unit coupled between the transceiver and the first OADM, wherein the optical configuration unit is operable to selectively couple the receiver to the first OADM so as to receive a first optical signal dropped from the first optical fiber or to selectively couple the transmitter to the first OADM so as to add a second optical signal to the first optical fiber.
A method, performed in a first optical network node, the method comprising:
- selectively coupling, using an optical configuration unit, a receiver of a transceiver to a first OADM, coupled to a first optical fiber, so as to drop a first optical signal from the first optical fiber or selectively coupling, using the optical configuration unit, a transmitter of the transceiver to the first OADM so as to add a second optical signal to the first optical fiber.
