Product Features
Technical Overview
This cable utilizes single-mode fiber with a core/cladding specification of 9/125 µm, optimized for long-distance transmission with minimal attenuation. It supports data transfer rates up to 1 Gbit/s, compatible with Gigabit Ethernet and other high-speed network protocols.
The duplex configuration features two independent fibers for simultaneous bidirectional communication, essential for full-duplex network operations. The ST and LC connectors are industry-standard interfaces, ensuring broad compatibility with existing network equipment.
This section brings together practical product details such as Cable Type, Cable Characteristic, Fiber Optic Mode, Color Family, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
Key Product Advantages
This patch cable delivers consistent performance and durability in network environments where reliability is critical. The combination of single-mode fiber and robust connectors minimizes signal degradation, supporting stable data transmission across infrastructure links.
Connector Reliability
ST and LC connectors provide secure, low-loss connections that resist dislodgement in high-vibration or frequently accessed patch panels.
- Precision-polished ferrules
- Durable metal housings
- Positive latching mechanisms
Safety & Compliance
The OFNR-rated PVC jacket meets plenum space fire safety standards, while TAA compliance ensures eligibility for government and institutional procurement.
- Flame-retardant jacket
- TAA compliant
- RoHS compliant materials
Deployment / Use Cases
This cable is ideal for connecting network switches, routers, servers, and storage devices in data centers where single-mode fiber is required for backbone or inter-building links. Its 9.8 ft length suits intermediate-distance patching within racks or between adjacent enclosures.
Common applications include telecommunications infrastructure, enterprise network core distribution, and high-performance computing clusters. The yellow color aids quick visual identification in dense cable management environments, streamlining maintenance and troubleshooting.
Data Center Patching
Connect core switches to distribution switches or link SAN/NAS storage arrays across racks with reliable single-mode fiber performance.
Telecom Cross-Connects
Use in central offices or POPs to interconnect optical line terminals (OLTs), multiplexers, or transmission equipment with ST/LC interfaces.

FAQ
What is the difference between single-mode and multimode fiber?
Single-mode fiber has a smaller core (9 µm) that allows only one light mode to propagate, enabling longer transmission distances with lower attenuation, typically used for backbone links over kilometers. Multimode fiber has a larger core (50 or 62.5 µm) that supports multiple light modes, suitable for shorter distances within buildings or campuses. This cable uses single-mode fiber for optimal long-distance performance.
What does OFNR jacket rating mean?
OFNR stands for Optical Fiber Non-Conductive Riser. This rating indicates the cable jacket is flame-retardant and suitable for installation in vertical riser shafts and plenum spaces without conduit, meeting NFPA and NEC safety standards for reduced fire spread and smoke emission in air-handling areas.
What devices are compatible with ST and LC connectors?
ST connectors are commonly used with older fiber optic equipment, media converters, and some telecom devices. LC connectors are the modern standard for high-density networking equipment like switches, routers, and SFP transceivers. This cable's ST-to-LC configuration bridges legacy and contemporary network infrastructure.
What is the maximum data transfer rate supported?
This cable supports data transfer rates up to 1 Gbit/s, making it compatible with Gigabit Ethernet, Fibre Channel, and other high-speed network protocols. The single-mode fiber and precision connectors ensure signal integrity at this rate over the cable's 9.8 ft length and beyond.
