Multimode Fiber Optic Patch Cord

In modern communication networks, fiber optic technology is the foundation for fast, reliable, and secure data transmission. Among the essential components, the multimode fiber optic patch cord plays a critical role in linking devices, patch panels, and distribution boxes with precision and stability.

At Shining Fiber, a professional fiber patch cord manufacturer and fiber optic solution provider, we specialize in producing multimode fiber optic patch cords that deliver superior performance, excellent durability, and maximum compatibility with today’s complex networking environments.

1. What is a Multimode Fiber Optic Patch Cord?

A multimode fiber optic patch cord, also known as a multimode jumper, is a short length of optical fiber cable terminated with connectors on both ends. It is primarily used for transmitting data over short to medium distances within buildings, data centers, and enterprise networks.

Unlike single-mode fibers, which use a small core to carry light over long distances, multimode fibers have a larger core (typically 50 μm or 62.5 μm), allowing multiple light modes to propagate simultaneously. This makes them ideal for high-capacity local networks and indoor fiber links where distances are typically less than 500 meters.

Common connector types for multimode patch cords include LC, SC, FC, ST, MTP/MPO, and E2000, with UPC or APC polishing as needed.

2. Multimode Fiber Patch Cord Structure

A standard multimode patch cord consists of four key layers:

Core – The central glass region that transmits the optical signal (50 μm or 62.5 μm).
Cladding – Surrounds the core and reflects light inward to maintain signal transmission.
Coating/Buffer – Protects the cladding from mechanical damage and moisture.
Outer Jacket – Typically made of PVC, LSZH (Low Smoke Zero Halogen), or OFNP material for flame retardance and flexibility.

Depending on the environment, patch cords may include armored tubes or pulling eyes for additional protection in harsh conditions, such as outdoor or industrial deployments.

3. Types of Multimode Fiber Patch Cords

Multimode patch cords are classified by fiber type, connector type, and cable construction.

(1) By Fiber Type

OM1 (62.5/125 μm) – Designed for up to 1 Gbps transmission, typically used for legacy networks.
OM2 (50/125 μm) – Supports up to 10 Gbps at 82 m, suitable for standard LANs.
OM3 (50/125 μm, laser-optimized) – Ideal for 10 Gbps up to 300 m; popular in data centers.
OM4 (50/125 μm, enhanced) – Supports 40/100 Gbps at 150 m; high-performance backbone choice.
OM5 (wideband multimode fiber) – Supports SWDM (Shortwave Wavelength Division Multiplexing) for 100 Gbps and beyond.

(2) By Connector Type

LC-LC, SC-SC, LC-SC, FC-SC, ST-ST, MTP/MPO etc.
Duplex versions carry both transmit and receive signals, while simplex versions carry one.

(3) By Jacket Type

PVC (OFNR) – General indoor use.
LSZH – Safer in enclosed environments; low smoke emission.
OFNP – For plenum spaces requiring strict fire safety.
Armored – Metal tube for anti-crush and anti-rodent protection.
FTTA / Outdoor Patch Cords – Rugged for base station and field use.

4. Advantages of Multimode Fiber Optic Patch Cords

1️⃣ High Bandwidth & Speed

Multimode patch cords transmit high-speed signals—10 Gbps, 40 Gbps, and 100 Gbps—making them perfect for modern data networks.

2️⃣ Cost-Effective Short-Distance Solution

Compared with single-mode systems, multimode systems use less expensive transceivers and components, reducing total network cost.

3️⃣ Easy Installation & Maintenance

Multimode connectors are user-friendly, and patch cords are easily plugged into patch panels, distribution boxes, or network switches without special tools.

4️⃣ Compatibility

Compatible with Ethernet, Fibre Channel, Infiniband, and other optical interfaces widely used in LAN, SAN, and data center systems.

5️⃣ Flexible Deployment

Available in various lengths, connector types, and cable constructions for indoor, outdoor, or armored installations.
