Transwarp conduit

From Memory Alpha, the free Star Trek reference

A transwarp conduit was an artificial construct that could be used to achieve faster-than-light travel, in a similar fashion to a wormhole. Vessels traveling in such conduits can traverse vast distances in a matter of hours. The Borg used this technology extensively.

A Borg transwarp conduit was first observed in the 2350s by the USS Raven. The opening of a conduit was characterized by triquantum waves, subspace disruptions with a field magnitude exceeding 2.9 teracochranes, and a symmetric power utilization curve. Inside the matter stream of the conduit, ships were accelerated to move forward. (VOY: "Dark Frontier")

The second time a transwarp conduit was observed occurred in 2369, by the USS Enterprise-D, during the pursuit of a rogue Borg ship. It was discovered that a conduit could be re-opened with a high-energy tachyon pulse emission on a specific tachyon frequency matrix that alternated between the low and secondary bandwidth frequencies. A closed mouth of a transwarp conduit was discovered to exhibit net external subspace transwarp distortions that fluctuated between 30 and 288 millicochranes. (TNG: "Descent")

Later discoveries by the USS Voyager during its journey in the Delta Quadrant revealed that the Borg maintained a vast network of transwarp conduits, allowing the Collective to reach any region in the galaxy. One such conduit opened within a light year of Earth. This conduit brought Voyager back to the Alpha Quadrant after its disabling of the transwarp hub. (VOY: "Endgame")

Conduits could be generated using The Borg transwarp drive, a technology that shared similarities with the quantum slipstream drive of Species 116. (VOY: "Hope and Fear") Such conduits were utilized by Voyager in 2375, after the capture of a transwarp coil. Using the coil, the Delta Flyer was able to open a conduit to Unimatrix 01. Upon its return, Voyager destabilized the conduit by sending a spread of photon torpedoes into the opening, destroying the Borg Queen's vessel that was still inside. The starship then used the coil to generate a conduit a further 20,000 light years towards the Alpha Quadrant. (VOY: "Dark Frontier")

In 2374, Seven of Nine attempted to generate a transwarp conduit by modifying the Voyager's main deflector to emit tachyon bursts. Unfortunately the experiment proved disastrous, as the transwarp frequency emissions caused a pressure increase in the warp core, flooding it with tachyons and nearly causing a breach.
