FieldCast 2Core 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 6.5 mm lead with a robust female FieldCast cable connector at each end, carrying 2 cores of protected Single mode 9/125 fiber.

It is colour coded with 2 yellow rings for 2Core single mode, so the right coupler is obvious in a crate of them.
