300 Meter Singlemode Duplex Fiber Optic Cable LC to LC - Reliable Link

In this review the 300 Meter Singlemode Duplex Fiber Optic Cable LC to LC is presented as a straightforward, no-nonsense solution for long inter-rack or campus runs where a clean, pre-terminated fiber link is needed. The biggest reason to buy is the combination of genuine Corning fiber and factory-terminated LC connectors that arrive ready to plug in, saving time on termination and testing. For IT technicians and installers who need a tested 300 m singlemode patch with OFNR jacketing, this cable delivers predictable insertion loss and installation simplicity.

Key Features

• Corning fiber and cladding: Uses trusted Corning glass for consistent singlemode performance across long runs.
• Pre-terminated LC to LC: Arrives with connectors on both ends to eliminate field termination and reduce deployment time.
• 100% inspected and tested for insertion loss: Each assembly is quality-checked so installers get a verified optical budget on delivery.
• OFNR jacketing: The riser-rated jacket provides a safer option for indoor vertical or riser pathways.
• PVC zip cord style: Flexible PVC construction makes routing through trays and conduits easier during installation.

Who It's For

This cable is ideal for network engineers, system integrators, and IT staff who need a reliable 300 m singlemode duplex link for campus backbone, inter-building links where singlemode is required, or high-speed inter-rack connections. It suits environments that need pre-tested assemblies to avoid on-site splicing or connector polishing.

Those who should look elsewhere include installers needing outdoor-rated, armored, or gel-filled fiber for direct burial, or users who require multimode fiber for short-distance 10G links inside a single rack; this product is singlemode only and optimized for indoor riser use.

Pros & Cons

Pros

• Pre-terminated LC ends save time and reduce the risk of field termination errors.
• Corning fiber and full insertion loss testing give dependable optical performance out of the box.
• OFNR jacketing and flexible PVC zip cord make it simple to route indoors and meet riser requirements.

Cons

• Not suitable for outdoor burial or direct-exposure runs because it is an indoor, non-armored cable.
