SpeedyCables OM4 LC–LC Fiber Patch Cable 30m (100ft)

This OM4 50/125μm duplex multimode fiber from SpeedyCables is built for modern data centers, telecom rooms and high-density networking racks that require reliable, low-loss links over medium distances. With LC-to-LC connectors, zirconia ferrules and a Low Smoke Zero Halogen jacket, the cable balances transmission performance, safety and ease of deployment. It supports a wide range of transceivers and provides predictable reach for common Ethernet speeds.

How far will this OM4 cable reliably carry 10G, 40G and 100G signals?

The OM4 specification increases modal bandwidth and usable reach versus OM3. SpeedyCables OM4 supports up to 400 meters for 10 Gigabit Ethernet, around 350 meters for 40 Gigabit links, and approximately 125 meters for 100 Gigabit short-range transceivers. Those distances depend on link components and transceiver types, but OM4 provides a comfortable margin for typical rack-to-rack and intra-room connections.

• 10G Ethernet: up to 400 m (typical)
• 40G Ethernet: up to 350 m (typical)
• 100G Ethernet: up to 125 m (typical)
• Modal bandwidth: 4700 MHz·km @850 nm for extended reach

What connector and optical performance can I expect from the LC-LC ends?

This patch cord uses duplex LC connectors with precision zirconia ceramic ferrules to minimize insertion loss and maximize return loss. Typical insertion loss is ≤0.3 dB per mated pair, and return loss performance is high enough for contemporary short-reach data transceivers. The small-form-factor LC enables dense patching in panels and switches.

• Connector type: LC-to-LC duplex
• Insertion loss: ≤0.3 dB (typical per connection)
• Return loss: ≥30 dB for reliable signal integrity
• Bend radius: 7.5 mm recommended for safe routing

Is the magenta LSZH jacket important for installation and safety?

The magenta jacket denotes OM4 multimode fiber for quick visual identification in mixed-cable environments. The LSZH (Low Smoke Zero Halogen) outer jacket reduces toxic fumes and dense smoke if exposed to heat, making it a preferable choice for indoor installations in populated or enclosed spaces. Its flexible construction also eases routing through racks and conduits.

• Jacket type: LSZH — low smoke and halogen-free
• Color: magenta for OM4 identification and easier cable management
• Application: safe for server rooms, telecom closets, and enclosed pathways
• Flexible jacket helps tight-radius routing and high-density panels

Which devices and transceivers is this cable compatible with?

The duplex OM4 LC-LC cable works with a broad set of multimode transceivers and network equipment that accept LC connectors. It pairs with SFP+, QSFP+, SR modules and many vendor optical modules designed for multimode short-range operation. Confirm transceiver fiber type and connector requirements before purchase to ensure end-to-end compatibility.

• Compatible transceivers: SFP+, QSFP+, SR, and other LC-based multimode modules
• Common uses: switch-to-switch, server I/O, SAN connections, patch panels
• Cross-vendor use: suitable for mixed-vendor racks when fiber types match
• Available lengths: 0.2 m to 200 m to fit rack, room and campus runs

Who is this for? Network engineers, data center technicians and IT teams who need dependable multimode fiber patching will benefit from the SpeedyCables OM4 LC-LC 30m patch cord. It’s aimed at environments that demand high throughput with predictable reach — from enterprise server rooms to co-location facilities — and for anyone prioritizing indoor safety with LSZH jacketing and clear cable identification. Choose this cable when you need compact LC connectors, low loss performance and a magenta OM4 jacket for fast identification in dense, mission-critical cabling systems.
