Fiber optic coupler set LOGILINK FA03LC9 — 2× LC Duplex (OM4, violet), SC‑Simplex breakout, 1 piece

LOGILINK FA03LC9 is a fiber optic coupler set intended for multimode OM4 infrastructure. Supplied as a single unit, the set contains two LC Duplex couplers in violet OM4 grading and an integrated SC‑Simplex breakout option. The product is designed for installation in patch panels, wall plates or inline enclosures where duplex LC connections are required with the ability to break out to an SC‑Simplex connector for compatibility with existing equipment.

Advantages

The coupler set provides standardized OM4 performance for short‑reach multimode applications, supporting consistent insertion loss and return loss characteristics typical of OM4 components. Its two LC Duplex ports offer compact duplex connectivity while the SC‑Simplex breakout allows straightforward adaptation to SC‑terminated links without additional adapters. The violet OM4 color coding helps maintain clear identification of higher‑grade multimode links in cabling infrastructure.

Suitable for

• Multimode OM4 backbone and horizontal cabling in data centers and server rooms
• Patch panels, fiber enclosures and wall plates requiring LC duplex terminations
• Retrofit or migration scenarios where breakout to SC‑Simplex is needed for legacy equipment
• Short‑reach links for high‑speed Ethernet, SAN or audiovisual distribution over multimode fiber

When it may not be suitable

This coupler set is intended for multimode OM4 fiber and is not suitable for singlemode applications or networks requiring singlemode performance and distances. It does not include transceivers, active components or pre‑terminated patch cords; those items must be selected separately to complete an end‑to‑end link.

Key specifications

• Fiber type: Multimode OM4
• Connector interfaces: 2× LC Duplex (violet), SC‑Simplex breakout
• Unit quantity: 1 piece (coupler set)
• Intended mounting: Patch panels, faceplates, inline enclosures

How to use

Install the coupler set into an appropriate panel cutout or adapter slot in a fiber enclosure or wall plate following the enclosure manufacturer's instructions. Terminate or plug LC Duplex patch cords into the LC ports for duplex transmission and connect an SC‑terminated cable to the SC‑Simplex breakout when required. Ensure connectors are clean before mating to minimize insertion loss, and secure the coupler within the panel to prevent mechanical stress on the fiber connections.

What to consider before purchase

• Compatibility with existing multimode OM4 cabling and color coding conventions
• Need for SC‑Simplex breakout versus full LC‑to‑LC termination
• Required quantity for the target panel or enclosure and spare parts planning
• Requirement for patch cords, transceivers or additional adapters not included with the set

Usage recommendations

Handle fiber connectors with appropriate cleaning tools and dust caps when not in use. Verify polarity and test each duplex link after installation with a suitable loss meter or OTDR configured for multimode OM4 to confirm expected performance.
