RamboCables LC to LC OM3 Multimode Fiber Patch Cable 15m

RamboCables LC to LC Multimode OM3 49ft (15m) duplex patch cable (2-pack) is a high-bandwidth, LSZH-jacketed fiber link built for 10G/40G/100G networking in data centers and enterprise racks.

This pair of 15-meter OM3 LC–LC fiber patch cords delivers low insertion loss and strong return loss through ceramic ferrules and a 50/125µm multimode core. Designed for dense patching environments, the 2.0mm duplex assembly and tight 7.5mm bend radius let you route cables neatly inside racks, patch panels, and telecom closets while meeting common transceiver requirements such as SFP+, QSFP+, and 10G SR optics.

How does this OM3 LC–LC cable support high-speed Ethernet?

The OM3 multimode specification provides high modal bandwidth suitable for short-reach, high-rate links. With a rated bandwidth of 4700 MHz·km at 850nm, these cables support 10GbE, 40GbE and short 100GbE applications over multimode fiber transceivers.

• 10GbE reach: up to 400 meters at 850nm.
• 40GbE reach: approximately 350 meters at 850nm.
• 100GbE reach: typical short-range support up to 125 meters at 850nm.
• Compatible with SFP+, QSFP+, and other multimode SR optics.

What performance and construction details should I expect?

RamboCables builds these OM3 cords with a 50/125µm glass core, zirconia ceramic ferrules, and a low-smoke zero-halogen (LSZH) jacket for cleaner installations. Factory-tested insertion loss is ≤0.3 dB and return loss ≥30 dB, ensuring predictable and repeatable signal behavior in patch panels and active equipment.

• Fiber diameter: 50/125µm multimode.
• Cable jacket: LSZH for reduced smoke and halogen in confined spaces.
• Insertion loss: ≤0.3 dB; return loss: ≥30 dB.
• Bend radius: 7.5 mm for tight routing without signal degradation.

Where is this duplex cable best used and how does the 2-pack help?

These LC–LC OM3 duplex cords are aimed at high-density installations where space and reliability matter, such as data centers, telecom rooms, and enterprise network closets. Buying a 2-pack reduces procurement complexity and provides matching, factory-tested pairs for linking switch ports to patch panels or transceivers to modules.

• Ideal for data centers, server rooms, and campus backbone links.
• Designed for patch panels, MPO conversions, and short-run trunking.
• 2-pack saves time and ensures matched performance between two cables.
• Works with 10G SR, 40G BIDI SR, QSFP+, and SFP+ transceivers.

How do safety and environmental specs affect installations?

The LSZH jacket reduces toxic smoke and corrosive gas in the event of a fire, making these cables preferable in enclosed public or commercial spaces. Operating temperatures from -20°C to 70°C and EIA/TIA-compliant ferrule construction make them robust for standard indoor deployments.

• LSZH jacket limits hazardous emissions in confined areas.
• Operating range: -20°C to 70°C for typical indoor environments.
• Meets EIA/TIA 604-2 standards; 100% inspected before shipping.
• Small 2.0mm diameter for high-density routing and cable management.

Who is this for: IT teams, network engineers, and system integrators who need reliable multimode patching for short-reach 10G/40G/100G links will benefit from the RamboCables 49ft OM3 LC–LC duplex 2-pack. It’s specifically aimed at environments requiring tight bend routing, space-efficient cabling, and LSZH safety, including data centers, telecom rooms, and enterprise network closets that deploy multimode SR optics.
