Adapter type

The Black Box FOT120 is a fiber optic duplex singlemode adapter built for joining two SC female connectors in patch panels or wall outlets. It suits network engineers and installers who need a straight-through ceramic-sleeve coupler for singlemode runs. The plastic housing meets RoHS and TAA requirements and carries a lifetime limited warranty from the manufacturer. It arrives new and ready for immediate deployment.

Compatibility check

Verify that both cables you plan to connect use SC connectors with singlemode ferrules and blue housing identifiers. Confirm the patch panel or outlet cut-out accepts a standard duplex SC footprint before ordering. Ensure the link budget accounts for the insertion loss of a ceramic-sleeve coupler in your singlemode span. No tools or power are required for the connection itself.

Who this suits

This coupler suits technicians extending or repairing point-to-point singlemode links with SC terminations. It is not suited for multimode fiber, APC-polished connectors, LC or ST interfaces, or any application requiring an active signal converter. Buyers needing higher port density or angled-polish alignment should evaluate alternative adapter styles.

Questions about this item

Does the FOT120 coupler ship with any patch cables or cleaning tools included?

The adapter is supplied as a single duplex SC female-to-female unit; patch cords and cleaning supplies are sold separately.

How do I decide between the FOT120 and a simplex version for my singlemode link?

Choose the FOT120 when you need to join two duplex patch cables or a duplex trunk in one housing; a simplex coupler handles only one fibre pair.

What does the blue colour on the SC sleeves indicate once the adapter is installed in a rack panel?

The blue sleeves identify singlemode ceramic ferrules, so technicians can verify the correct polish type at a glance during installation.
