Fiber Optic Patch Cord | SC LC FC ST MPO Connectors for Network Connectivity

Introduction

Opelink is a leading manufacturer of fiber optic patch cords, providing high-quality connectivity solutions for data centers, telecommunications networks, and enterprise applications. With 13+ years of experience and ISO 9001:2015 certification, we deliver reliable patch cords to customers in over 50 countries.

Fiber optic patch cords, also known as fiber jumpers or patch cables, are essential components for connecting network devices, patch panels, and optical equipment. Opelink offers a comprehensive range of patch cords with various connector types (SC, LC, FC, ST, MPO/MTP), fiber modes (single mode OS2, multimode OM3/OM4/OM5), and cable configurations (simplex, duplex, uniboot).

All our patch cords are manufactured with precision-polished ceramic ferrules and undergo 100% insertion loss testing to ensure optimal performance. We provide custom lengths, colors, and labeling to meet specific project requirements, with competitive factory-direct pricing for bulk orders.

Patch Cord Types

Opelink offers comprehensive patch cord solutions to meet diverse network requirements:

1. Single Mode Patch Cords (OS2)

• 9/125μm core for long-distance transmission
• Available with SC, LC, FC, ST, E2000 connectors
• UPC and APC polish options
• Low insertion loss ≤0.3dB
• For telecom, CATV, and long-haul applications

2. Multimode Patch Cords

• OM3 (10GbE up to 300m), OM4 (10GbE up to 550m), OM5 (SWDM)
• 50/125μm laser-optimized fiber
• LC and SC connectors (standard for data centers)
• For high-speed data center and enterprise networks

3. MPO/MTP Patch Cords

• 8, 12, 24 fiber configurations
• Single mode and multimode options
• For high-density data center connections
• Compatible with 40G/100G/400G transceivers

4. Armored Patch Cords

• Steel armoring for rodent protection and crush resistance
• For industrial and harsh environment applications
• Maintains flexibility while providing enhanced durability

5. Uniboot Patch Cords

• Single boot design for duplex connections
• Reduced cable bulk in high-density panels

Connector Options

.SC Connector: 2.5mm ferrule, push-pull coupling, reliable and widely used in telecom networks. Available in simplex and duplex configurations.
.LC Connector: 1.25mm ferrule, latch coupling, half the size of SC. The standard for high-density data center applications.
.FC Connector: 2.5mm ferrule, threaded coupling, excellent for vibration-resistant applications. Common in test equipment and industrial environments.
.ST Connector: 2.5mm ferrule, bayonet coupling, traditional connector still widely used in industrial and legacy networks.
.MPO/MTP Connector: Multi-fiber push-on, 8/12/24 fibers in one connector. Essential for 40G/100G/400G data center connections.

Applications

• Data Centers: Server-to-switch, switch-to-switch connections
• Telecommunications: Central office, outside plant, FTTH networks
• Enterprise Networks: LAN, campus, building backbone connections
• CATV Networks: Headend, distribution, and subscriber connections
• Industrial Networks: Factory automation, process control systems
• Test & Measurement: Laboratory and field testing applications
• Military/Aerospace: Ruggedized solutions for harsh environments

FAQ

Q1: What is the difference between single mode and multimode patch cords?

A: Single mode patch cords use 9/125μm fiber for long-distance transmission (up to 100km+) at 1310nm and 1550nm wavelengths. Multimode patch cords use 50/125μm or 62.5/125μm fiber for shorter distances (up to 550m for OM4) at 850nm and 1300nm. Single mode is used in telecom and long-haul; multimode is used in data centers and LANs.

Q2: What is the difference between UPC and APC connectors?

A: UPC (Ultra Physical Contact) has a flat polished end face with typical return loss of ≥50dB, suitable for most applications. APC (Angled Physical Contact) has an 8-degree angled polish with return loss ≥60dB, used in applications requiring minimal back reflection such as CATV, PON, and high-speed digital systems.

Q3: What cable jacket material should I choose?

A: PVC is the standard economical choice for indoor applications. LSZH (Low Smoke Zero Halogen) is required for enclosed spaces where fire safety is critical. OFNR (Optical Fiber Non-conductive Riser) is rated for vertical runs between floors. OFNP (Optical Fiber Non-conductive Plenum) is rated for air handling spaces with strictest fire safety requirements.

Q4: Can you provide custom lengths and colors?

A: Yes, Opelink offers custom lengths from 0.3m to 100m or longer. We provide various jacket colors (yellow for OS2, aqua for OM3, magenta for OM4, lime green for OM5) and can produce custom colors for specific project requirements. Custom labeling and packaging are also available.

Q5: What is your quality assurance process?

A: All Opelink patch cords undergo 100% insertion loss and return loss testing using calibrated test equipment. We use ceramic ferrules from certified suppliers and precision polishing equipment. Each patch cord is individually bagged with test data included.
