OM3 Fiber Pigtail

OM3 Fiber Pigtail, 50/125µm;

Tight tube cable: Tight tube buffer structure, no gel;

Loose tube cable: Loose tube buffer structure, waterproof cable sheath;

Indoor cable: Light green low-smoke zero-halogen cable sheath, no metal components;

Indoor/outdoor cable: Enhanced black low-smoke zero-halogen cable sheath, corrosion-resistant, no metal components, UV protection, and moisture resistance.

OM3 Fiber Pigtail offers many advantages, making it an excellent choice for high-capacity, high-performance network infrastructure:

• Core diameter: 50μm, supports multiple light modes and enables fast data transmission.
• Bandwidth: Fiber optic patch cables in various configurations offer bandwidth capacities up to 2000 MHz/km, transmission distances up to 300 meters, and transmission rates up to 10 Gbps.
• Laser Optimization: These fibers operate best when combined with VCSELs (Vertical Cavity Surface-Emitting Lasers) with a wavelength of approximately 850nm. Therefore, they offer higher speeds and reliability than other standards such as OM2, OM3, and OM4.
• Proven Applications: Widely used in data centers (DCs), local area networks (LANs), and storage area networks (SANs). Compared to OM1 fiber, it is reliable and supports scalable network requirements.
• Compatibility: It can be integrated into existing systems due to its backward compatibility with older multimode fiber optic cables, such as OM1 or OM2.

These characteristics make this cable an ideal choice for high-speed and reliable modern communications systems.

 

Q：Multimode OM3 fiber optic patch cord insertion loss requirements

The insertion loss of a multimode OM3 fiber patch cord is 0.35dB, and the return loss is 35dB. However, in general, the insertion loss of a multimode fiber patch cord is ≤0.2 dB (PC); ≤0.2 dB (UPC); ≤0.3 dB (APC). Return loss: ≥45dB (PC); ≥50dB (UPC); ≥60dB (APC).

Q：What color is OM3 Fiber Pigtail?

OM3 multimode fiber is aqua.
OM3 fiber also has two ratings: 150m and 300m. This means that for both 10G transmission, one has a 150m rating and the other has a 300m rating. Although the colors of the OM3 fiber patch cables in the two images above differ, this is primarily due to differences in material and does not affect transmission parameters. Please be sure to read the markings carefully.

Q：What network applications are suitable for OM3 Fiber Pigtail?

OM3 fiber is a laser-optimized multimode fiber suitable for a variety of network applications. The following is a detailed introduction:

Data Center: OM3 fiber is widely used in data centers, supporting high-speed data transmission and high bandwidth requirements.

Local Area Network (LAN): OM3 fiber is suitable for in-building LANs, providing stable and high-speed network connections.

Storage Area Network (SAN): OM3 fiber is also used in storage area networks, ensuring fast and reliable data transmission.

Inter-Building Connections: OM3 fiber can be used to connect networks between different buildings, supporting data transmission over longer distances.

Q: I'm building a 10 Gigabit network. How should I choose between OM3, OM4, and OM5 fiber optic pigtails? Is newer always better?

Conclusion: For most newly built 10 Gigabit (10GbE) networks, OM3 Fiber Pigtail offer the best cost-effective starting point. The choice isn't necessarily the newest, but rather depends on specific needs and budget.

One-sentence advice: Use OM3 for current needs, OM4 for future needs, and consider OM5 only for cutting-edge ultra-high-speed applications.

Q: When buying OM3 Fiber Pigtail, besides length and connectors, what key quality indicators should I pay attention to? How can I avoid buying inferior products?

Besides appearance (length, connector type such as LC/SC), you should pay attention to the following core performance indicators, as they are crucial for link stability:

Insertion loss and return loss are key electrical performance indicators:

Insertion loss: The power attenuation of the optical signal after passing through the pigtail. A high-quality OM3 Fiber Pigtail should typically have an insertion loss of ≤ 0.3 dB for a single-ended connector and ≤ 0.6 dB for the entire length (both ends). Excessive loss can lead to reduced transmission distance or link instability. Return loss: A measure of the amount of light reflected from the connector's end face. High-quality products should have ≥ 35 dB (APC end face) or ≥ 20 dB (UPC end face). Insufficient return loss can cause light source fluctuations and increase the bit error rate.

Identifying quality through appearance and certification:

Check the sheath and markings: High-quality fiber optic pigtail sheaths (light blue) are flexible and smooth, clearly printed with the brand, model (e.g., OM3), length, and certification marks (e.g., conforming to IEC 60793-2-10 standard).

Check the connector's workmanship: The ceramic ferrule should be clean and free of scratches, with uniform color; the sleeve should be accurately aligned, and the latches should be secure and without wobbling.
