OM4 Multimode Fiber FAQ: High-Speed Connectivity Guide

What is OM4 Fiber?

What is the Difference Between OM4 Patch Cables and Other Multimode Patch Cables?

1. OM4 (Optical Multimode 4) is a type of multimode fiber optic cable that is designed to support higher data rates and longer distances compared to previous multimode fibers like OM1, OM2, and OM3. The key differences between OM4 patch cables and other multimode patch cables (specifically OM1, OM2, and OM3) lie in their bandwidth, data rates, and transmission distances.

• Bandwidth:

OM1: Supports 1 Gbps up to 300 meters.

OM2: Supports 1 Gbps up to 500 meters.

OM3: Supports 10 Gbps up to 300 meters.

OM4: Supports 10 Gbps up to 550 meters.

• Data Rates：

OM1 and OM2: Primarily designed for 1 Gbps data rates.

OM3 and OM4: Designed to support 10 Gbps and higher data rates.

• Transmission Distances:

OM1 and OM2: Typically used for shorter distances within data centers or local area networks (LANS).

OM3 and OM4: Provide higher bandwidth and support longer transmission distances, making them suitable for high-speed networks, especially in data centers.

• Core Size:

OM1: Have a core size of 62.5 microns.

OM2, OM3 and OM4: Have a smaller core size of 50 microns.

What is the Maximum Data Rate that OM4 Fiber Supports?

• 10 Gbps (Gigabits per second): OM4 fiber can support 10 Gbps over a distance of up to 550 meters.

• 40 Gbps (Gigabits per second): At 40 Gbps, the maximum supported distance is reduced to 150 meters.

• 100 Gbps (Gigabits per second): OM4 fiber can support 100 Gbps over a distance of up to 150 meters.

What are the Key Advantages of Using OM4 Patch Cables?

OM4 patch cables offer several key advantages in high-performance networking environments. With higher bandwidth capabilities, they support increased data transfer rates and are optimized for applications such as 40GbE and 100GbE. Their extended reach provides flexibility in network design, and their backward compatibility allows for seamless upgrades in existing installations. Additionally, OM4 cables are cost-effective for short-distance applications, striking a balance between performance and affordability. The aqua-colored jacket aids easy identification, and adherence to industry standards ensures interoperability and reliable performance in diverse networking setups.

Are OM4 Patch Cables Compatible with Multimode Patch Cables?

1. Certainly. OM4 patch cords are designed with a 50-micron core size, making them compatible with other multimode patch cords like OM3 and OM2. This compatibility stems from their shared core size, allowing for seamless integration and flexibility in network design. This means that if you have an existing infrastructure utilizing OM3 or OM2, you can introduce OM4 patch cords for enhanced performance without the need to replace the entire cabling system. This backward compatibility supports a phased and cost-effective approach to network upgrades. However, it is crucial to maintain consistency in multimode fiber standards across all components, including connectors and adapters, to ensure optimal performance and reliability in the network.

What Types of Connectors are Available for OM4 Patch Cables?

OM4 patch cables come with a variety of connectors, including LC, SC, ST, MTP/MPO, and others. The choice of connector depends on the specific requirements of the network and the equipment being used. And FS's OM4 patch cables support a wide range of connectors, which can be customized to meet various needs based on different scenarios.

Which Optical Transceiver Modules are OM4 Patch Cords Compatible with?

OM4 patch cables are compatible with a variety of optical transceivers or modules that support multimode fiber connectivity. The choice of module depends on the specific requirements of your network equipment and the application. Some common optical modules compatible with OM4 patch cables include:

• 1. SR (Short Range) Modules: These are typically used for short-distance connections and are common for 10 Gigabit Ethernet (10GbE) applications.

• 2. SR4 (Short Range 4) Modules: These modules are designed for higher data rates, often used in 40 Gigabit Ethernet (40GbE) applications.

• 3. SR10 (Short Range 10) Modules: Used in high-density environments, SR10 modules support 100 Gigabit Ethernet (100GbE) applications.

• 4. MTP/MPO Modules: Multi-Fiber Push-On (MTP) or Multi-Fiber Push-On Connectors (MPO) modules are often used for high-density, high-speed connections in data centers.

• 5. QSFP (Quad Small Form-Factor Pluggable) Modules: These modules support various data rates and are commonly used in high-performance networking equipment.

When selecting modules for OM4 patch cables, it's essential to ensure compatibility with the specific connectors on the patch cables (e.g., LC, SC, MTP/MPO) and the networking equipment in use. Always refer to the specifications provided by the module and cable manufacturers to ensure proper compatibility and optimal performance.

Can OM4 Cables be Used for Both Short-distance and Long-distance Applications?

While OM4 fiber is optimized for short-distance applications, its performance is excellent for distances commonly found in data centers. For longer-distance applications, such as over ten kilometers, single-mode fibers like OS2 are more suitable.

In What Scenarios Would Someone Choose OM4 Fiber Over Copper Cables?

OM4 fiber is preferred over copper cables in scenarios where higher bandwidth, faster data rates, and immunity to electromagnetic interference are critical. Data centers, where high-performance networking is essential, often choose OM4 fiber for its superior characteristics.

What are the Considerations When Selecting OM4 Patch Cables for a Specific Application?

Considerations include the required data rate, the distance the signal needs to travel, the type of connectors needed for the equipment, and the overall network architecture. It's essential to match the cable specifications with the specific requirements of the application.

Can FS.com Provide OM4 Multimode Fiber?

Yes. Currently, FS can provide OM4 patch cables with various lengths and connectors, and you can customize the patch cables you need according to your requirements.
