FieldCast 4Core SM Coupler Cable, 50 cm

A FieldCast main cable is terminated male at both ends, so joining two drums needs a female-to-female link. That is what this 50 cm coupler is: a short 7.5 mm lead with a robust female FieldCast cable connector at each end, carrying 4 cores of protected Single mode 9/125 fiber.

It is colour coded with 4 yellow rings for 4Core single mode, so the right coupler is obvious in a crate of them.
