Product information

Description

ROLINE 21.17.0051 SC/SC Female OS2 is an inline fibre optic adapter designed for single-mode OS2 networks. The adapter provides SC duplex interfacing with female connectors on both ends, enabling low-loss single-mode connections between SC-terminated patch cords, patch panels and fibre enclosures. The compact keystone-format plastic housing and ceramic ferrule sleeve ensure stable alignment and optical performance while keeping weight minimal for easy installation and handling.

Advantages

The adapter supports single-mode OS2 transmissions and features a ceramic sleeve for precise ferrule alignment, reducing insertion loss and back reflection. Its keystone format allows straightforward mounting in compatible front plates or modules, and the durable plastic housing offers mechanical stability in patch panels and enclosures. The lightweight design simplifies handling and installation without compromising connection reliability.

Suitable for

Connecting SC-terminated single-mode patch cords
Extending fibre optic jumper cables
Integration into keystone-compatible patch panels and faceplates
Interfacing network equipment with SC ports in single-mode links

Key specifications

Connector type: SC female to SC female (duplex inline adapter)
Fibre mode: Single-mode (OS2)
Ferrule sleeve material: Ceramic
Housing format: Keystone-style plastic adapter
Typical application: Patch panels, fibre enclosures, cable extensions
Weight: approximately 4.6 g

How to use

Install the keystone-format adapter into a compatible front plate or module by pressing it into the keystone opening until it locks. To connect fibres, insert SC-terminated single-mode patch cords into each side of the adapter until they click in place, ensuring clean connectors and proper insertion to maintain low loss. For inline extension of jumper cables, align the SC plugs with the adapter openings and insert firmly. When disconnecting, depress any retention clips on the patch cords and pull straight out to avoid bending the fibres.

Usage recommendations

Use with clean SC single-mode connectors and observe standard fibre handling practices: keep endfaces protected with dust caps when not in use, clean connectors before mating, avoid sharp bends and excessive tension on cables, and perform insertion loss or reflectance checks when integrating into critical single-mode links.
