Abstract
Some implementations include a system configured for use in a wellbore drilled through one or more subsurface formations, the system comprising a first downhole tool positioned along a tubular in the wellbore and a first cable including one or more fiber optic cables, wherein the first cable is coupled with the tubular external to the first downhole tool. The system further includes a control system coupled with the first cable and a transceiver coupled to the first downhole tool, wherein the transceiver is configured to transmit an uplink transmission, via the one or more fiber optic cables, from the first downhole tool to the control system.

A system configured for use in a wellbore drilled through one or more subsurface formations, the system comprising:
- a first downhole tool positioned along a tubular in the wellbore;
- a first cable including one or more fiber optic cables, wherein the first cable is coupled with the tubular external to the first downhole tool;
- a control system coupled with the first cable;
- and
- a transceiver coupled to the first downhole tool, wherein the transceiver is configured to transmit an uplink transmission, via the one or more fiber optic cables, from the first downhole tool to the control system.
An apparatus configured for use in a wellbore formed in one or more subsurface formations, the apparatus comprising:
- a first downhole tool positioned along a tubular in the wellbore;
- a first cable including one or more fiber optic cables, wherein the first cable is coupled with the tubular external to the first downhole tool;
- and
- a transceiver coupled to the first downhole tool, wherein the transceiver is configured to transmit an uplink transmission, via the one or more fiber optic cables, from the first downhole tool.
A method comprising:
- generating an uplink transmission from a first downhole tool positioned in a wellbore formed in one or more subsurface formations to a control system positioned at a surface of the wellbore, wherein generating the uplink transmission comprises, encoding, via a transceiver coupled to the first downhole tool, the uplink transmission, and
- transmitting, via one or more fiber optic cables, the uplink transmission to the control system, wherein the first downhole tool is wirelessly coupled with the one or more fiber optic cables.
