RamboCables OM3 LC-LC Multimode Fiber Patch Cable 4m 8-Pack

RamboCables OM3 LC to LC multimode fiber patch cable 8-pack delivers high-speed, low-loss duplex connections for 10G/40G/100G networks in a 13.1ft (4m) LSZH jacket.

These OM3 LC-LC fiber patch cords are engineered for data centers, telecom rooms and enterprise racks that need consistent multimode performance and compact duplex connections. Each 4m cable uses 50/125µm fiber cladding, zirconia ferrules and a low-smoke zero-halogen (LSZH) jacket for safer installations in enclosed spaces. The 8-pack format reduces procurement cost and simplifies high-density cabling projects.

How does this OM3 cable support 10G, 40G and 100G networks?

OM3 multimode fiber provides the modal bandwidth and core size required for short-range high-speed Ethernet. With a specified bandwidth of 4700 MHz·km at 850nm, these LC-to-LC duplex cables meet the reach expectations for common multimode transceivers.

• 10GbE: up to 400 meters at 850nm
• 40GbE: up to 350 meters at 850nm using appropriate QSFP+ transceivers
• 100GbE: supported up to 125 meters at 850nm with proper breakout or SR optics

What construction and performance specs should I expect?

RamboCables builds these OM3 patch cords to industry tolerances for low insertion loss and stable return loss. Materials and testing ensure consistent signal integrity across every cable in the 8-pack.

• Fiber type: OM3 multimode, 50/125µm core/cladding
• Connectors: LC duplex with zirconia ceramic ferrules, compliant with EIA/TIA 604-2
• Optical metrics: insertion loss ≤0.3 dB, return loss ≥30 dB
• Environmental: operating temperature -20°C to 70°C; bend radius 7.5 mm

Will these cables fit high-density racks and safety requirements?

The 2.0 mm jacket diameter and LC duplex connectors are chosen for space-efficient routing and cable management in crowded panels. The LSZH outer jacket reduces toxic gas and smoke if exposed to fire, a common requirement in many indoor installations.

• Compact 2.0 mm diameter for tighter bend and neat routing
• LSZH jacket for reduced smoke and halogen-free composition
• Duplex LC connectors save port space compared with larger connector types

Who is this for? Network engineers, data center operators and IT teams that need reliable, short-range multimode links will benefit from the RamboCables OM3 LC-LC 4m 8-pack. It’s aimed at installations that require consistent 10G/40G/100G performance, compact duplex connections for high-density panels, and an LSZH jacket for safer indoor environments. The bulk 8-pack reduces procurement time and per-unit cost, making it practical for rack deployments, cross-connects, and telecom closets where predictable multimode performance matters.
