Fibre optic cable Synergy 21 S216294 2m LC SC Violet

The Synergy 21 S216294 2m LC–SC fibre optic cable is a 2‑metre duplex OM4 patch cable with LC connector on one end and SC connector on the other. It uses a 50 µm core multimode fibre designed for high‑speed data transmission and low attenuation across short to medium distances. The cable's violet jacket and 3 mm outer diameter identify it as an OM4 multimode link suitable for structured cabling, data centre interconnects and equipment patching where LC and SC interfaces are required.

Advantages

This OM4 fibre cable supports full duplex communication and is designed for stable, low‑loss connections between devices with LC and SC ports. The 50 µm core enables higher bandwidth and better modal dispersion performance than lower graded multimode fibres, which helps maintain signal integrity for high data rates. The 2 m length provides flexibility for rack and patch‑panel routing while keeping insertion loss minimal. The standardized connector types ensure broad compatibility with networking equipment.

Suitable for

• Patch connections between switches, transceivers and patch panels in data centres and server rooms
• Connecting multimode optical transceivers and network equipment with LC and SC ports
• Short‑to‑medium distance links in enterprise networks, telecom racks and campus cabling

When it may not be suitable

This OM4 multimode cable is not suitable for long‑haul singlemode applications or installations that require singlemode fibre. It is also not appropriate where length runs exceed the supported multimode distance for the required data rate; in such cases a different fibre grading or longer link design is necessary. The fixed 2 m length may limit use in installations that need custom or very short patch cords.

Key specifications

• Fibre type: Multimode, 50 µm core (OM4)
• Length: 2 metres
• Connector A: LC duplex
• Connector B: SC duplex
• Mode: Full duplex
• Outer diameter: approximately 3 mm
• Jacket colour: violet

How to use

Route the cable between the devices to be connected, avoiding sharp bends and tight loops to prevent increased attenuation. Insert the LC connector into the LC port and the SC connector into the SC port until each snaps or seats securely. Use appropriate cable management such as horizontal managers or Velcro ties to secure the cord and maintain bend radius. For best performance, keep connectors clean and protect unused ends with dust caps until installation is complete.

What to consider before purchase

• Confirm that both devices support multimode fibre and have matching connector types (LC and SC).
• Verify that OM4 multimode performance meets the required distance and data rate for your application.
• Ensure 2 m length is sufficient for the intended patching path and rack layout.
• Check whether duplex orientation and connector polarity match your existing cabling scheme.

Usage recommendations

To maintain signal quality, inspect and clean fibre endfaces before mating, avoid bending the cable beyond the manufacturer’s minimum bend radius, and store unused connectors capped. Use the Synergy 21 OM4 LC–SC 2 m cable for short interconnects where multimode optics provide the required throughput and compatibility with LC and SC interfaces.
