Abstract: An optical fiber connection unit has a circuit board with a hole formed therein, oval shaped inner and outer channels separated by an oval shaped separating wall, extension supports and a standoff. The oval shaped inner channel has a radius at least as large as a minimum bend radius of a polymeric optical fiber. The oval shaped outer channel follows the inner channel, but has a larger radius than the inner channel. The oval shaped separating wall has a plurality of openings formed therein where passage between the inner and outer channels is possible. The extension supports extend between the opposing sides of the inner channel. The extension supports meet at an intersection thereof, and a connection hole is formed at the intersection where the extension supports meet. The standoff is removably secured to both the hole in the circuit board and the connection hole formed at the intersection of the extension supports.
