SpeedyFiberTX 6-Pack 3m LC-LC Singlemode Patch Cables

If you need compact, low-loss singlemode jumpers for switches, SFP transceivers, patch panels or FTTH terminations, these 3 meter LC-to-LC cables deliver industry-grade Corning SMF-28 Ultra optical fiber performance in an easy-to-deploy zipcord format. Each cable in this six-pack uses 9/125µm fiber, precision ceramic ferrules in LC duplex connectors, and a 2.0 mm yellow OFNR jacket to meet riser-rated building installations while keeping the cabling neat and identifiable.

How do these cables affect signal performance in my network?

These patch cords are manufactured with Corning SMF-28 Ultra fiber, optimized for lowest possible attenuation across the 1285–1625 nm range. Each connector termination is tested for insertion and return loss, so you get predictable optical performance for transceiver links and fiber runs.

• Insertion loss ≤ 0.2 dB per connector pair for minimal signal drop
• Return loss ≥ 50 dB to reduce back-reflection into sensitive optics
• Attenuation ≤ 0.32 dB/km at 1310 nm and ≤ 0.18 dB/km at 1550 nm
• Operating bandwidth across 1285–1625 nm for broad transceiver compatibility

Are these cables easy to identify and install in racks or panels?

The duplex zipcord format and color-coded heat-shrink make channel identification fast and prevent cross-connection. Short LC boots and a slim 2.0 mm jacket let the cords route cleanly around densely packed equipment without adding bulk.

• Yellow OFNR jacket for quick singlemode identification in mixed cable runs
• Color-coded heat shrink on each LC for immediate transmit/receive matching
• Compact 2.0 mm zipcord profile for tight bend spaces and cable managers
• Short connector boots reduce strain and save panel space

Will these cables meet building and compatibility requirements?

Yes — the jacket is OFNR-rated PVC for riser installations and the fiber meets ITU standards for singlemode applications. The SMF-28 Ultra specification provides backward compatibility with legacy SMF fibers, so splicing and system integration remain straightforward.

• Riser-rated OFNR PVC jacket suitable for vertical riser spaces
• Ferrules made from ceramic for stable, repeatable terminations
• Compliance with ITU, UL, CE, IEC, TIA and RoHS standards
• Designed to splice and operate with installed singlemode fiber bases

How durable and reliable are these connectors during deployment?

Each LC duplex connector is constructed for repeated matings and tested to ensure loss specifications are met before shipping. The cable's improved bend performance reduces the risk of macrobend losses in tight routing environments without compromising attenuation.

• 100% insertion loss and return loss inspection for quality assurance
• SMF-28 Ultra fiber with enhanced bend resistance compared to standard SMF
• Durable PVC jacket and strain-relieved short boots for everyday handling
• Lightweight cable profile reduces mechanical stress on terminations

Who is this for: Network engineers, data center technicians, telco installers and IT managers who need reliable, low-loss singlemode patch leads for SFP transceivers, switches, media converters and patch panels. The SpeedyFiberTX 6-pack is tailored for projects that demand consistent optical performance, clear fiber channel identification and tidy cable management in riser-rated building environments.
