RamboCables OM4 LC to LC Patch Cable 13ft/4m – 4-Pack Duplex MMF, LSZH

Overview

Engineered for reliability in data centers and enterprise networks, the RamboCables OM4 LC to LC fiber patch cable comes in a 4-pack of 13-foot (4-meter) duplex links. Each cord uses 50/125 μm high‑quality multimode fiber, with 850 and 1300 nm wavelengths that support up to 10G/40G/100G links while keeping a compact 2.0 mm diameter and a glow of safety thanks to LSZH jacket.

Key benefits at a glance

• OM4 multimode fiber with wide bandwidth (4700 MHz·km @850 nm) for longer reaches within data fabrics.
• Low insertion loss (≤0.3 dB) and solid return loss (≥30 dB) for clearer signal in high‑density cabling.
• Durable, environmentally friendly LSZH jacket suitable for busy racks and telecom rooms.
• Broad compatibility with 10G SR, 40G BIDI SR, QSFP+, and SFP+ transceivers for flexible upgrades.
• Temperature tolerance from -20°C to 70°C keeps performance in a range of data environments.
• Compact bend radius (7.5 mm) and 2.0 mm cable diameter help maximize cabinet space.

In practice, these cables are well suited for data centers, university labs, enterprise networks, and telecom rooms where space, organization, and dependable links matter. The 4-pack packaging provides a convenient, cost‑effective way to equip racks with matching cables, avoiding mismatches or last‑minute trips to the supplier. The LSZH jacket adds an extra layer of safety in crowded racks and cable trays, while 13-foot legs offer ample reach between patch panels and transceivers.

Performance by the numbers

• 10G Ethernet: up to 400 meters at 850 nm, enabling long‑haul desktop and edge connections.
• 40G Ethernet: up to 350 meters at 850 nm, supporting high‑density spine links.
• 100G Ethernet: up to 125 meters at 850 nm, suitable for modern data fabrics.
• Specifications compliance: low insertion loss, high return loss, and zirconia ceramic ferrule stability (per EIA/TIA 604-2).

Designed to balance reliability, safety, and ease of deployment, these cables offer a practical path to upgrading and expanding networks. If you’re building a new rack‑dense environment or refreshing existing links, a bulk 4‑pack helps simplify procurement and consistency across the network. As with all fiber links, careful handling of connectors and adherence to recommended bend radii will help preserve signal quality over time.
