Indoor and Outdoor Panel-to-Panel Optical Wiring

Connecting Optical Connectors
Optical connectors must be connected on-site in the following situations.
• The exact cable length cannot be decided because the cabling route is unknown.
• There is no work site where excess cable lengths can be treated.
• There is no work site (approximately 1 m × 1 m) where optical connectors can be con-
• It is difficult to lay optical fiber cords or cables equipped with a connector because there
On-site optical connector connection must always be done by those who have completed a connector

radius, and through-hole diameter restrictions apply when a cover is used to protect the
tip of a connector during cable installation.
Unless there are special circumstances as above, it is recommend to purchase optical
fiber cords or cables equipped with optical connectors at both ends.
