ST Series Fiber Optic Patch Cord Industry Knowledge Analysis

1. Product Definition and Core Features
What are the main design goals of the ST Series Fiber Optic Patch Cord?

ST (Straight Tip) interface fiber optic patch cord is an early and widely used single-mode/multimode fiber connection solution. Its core design goal is to provide a physical connection with high stability and low insertion loss, which is suitable for scenarios such as data centers, local area networks (LANs) and telecommunications transmission.

Ningbo Goshining Communication's ST patch cord uses a ceramic sleeve (Ferrule) and high-precision polishing process to ensure that the end face flatness is ≤0.1μm, effectively reducing the return loss (RL≥50dB), and meeting the ITU-T G.652/G.657 standard.

Compared with SC/LC patch cords, what are the advantages and limitations of ST patch cords?

The ST interface uses a metal snap-on locking structure to achieve fast plugging and unplugging, which is suitable for frequent plugging and unplugging scenarios (such as test equipment), but its large size and plugging and unplugging require rotation operations, which limits its application in high-density wiring environments.
Ningbo Goshining Communication has significantly improved the plug-in life (≥500 times) by optimizing the clip spring tension (0.5-1.2N), and provides IP67 protection level options to adapt to harsh outdoor environments.

2. Application scenarios and technical adaptability
In which scenarios are ST jumpers still irreplaceable?
Although LC/MPO interfaces have gradually become mainstream, ST jumpers are still widely used in:

Traditional communication equipment upgrades: such as old switches and optical transceivers (compatible with equipment from Huawei, ZTE and other manufacturers);
Industrial automation control: The electromagnetic interference in factory workshops is strong, and ST's metal shell provides better shielding performance;
Medical endoscope system: High-definition images need to be transmitted through optical fiber, and ST's low loss characteristics ensure signal integrity.
Ningbo Goshining Communication has developed armored ST jumpers for industrial scenarios. The outer layer uses a stainless steel spiral sheath, which increases the crushing strength by 300% and extends the life to more than 10 years.

How to choose single-mode and multi-mode ST jumpers?
Single-mode (OS2): Suitable for long-distance transmission (≥10km), such as metropolitan area network backbone links;
Multi-mode (OM3/OM4): Supports short-distance high-speed transmission (≤550m@10Gbps), commonly used for interconnection within data center cabinets.
Ningbo Goshining Communication uses DMD (differential mode delay) testing to ensure the bandwidth of multi-mode jumpers. OM4 products support 40G/100G Ethernet and are compatible with IEEE 802.3ba standards.

3. Quality control and industry certification
What are the key quality indicators of fiber jumpers?
Insertion loss (IL): Ningbo Goshining Communication controls IL to ≤0.2dB (single-mode)/≤0.3dB (multi-mode) through 3D interferometer detection;
Return loss (RL): Adopting UPC/APC end face design, RL is ≥50dB/≥65dB respectively;
Environmental adaptability: Passing -40℃~+85℃ high and low temperature cycle test to ensure stable performance under extreme temperatures.

How does Ningbo Goshining Communication ensure product reliability?
The company has ISO 9001:2015 quality management system certification. All ST patch cords must undergo 100% end face inspection, 36-hour aging test and FiberChek fiber detector verification. In addition, the company supports customized services, such as non-standard length (0.5m-100m), special color identification (for easy wiring management) and customer LOGO printing.

4. Industry trends and competitive advantages
What is the future development direction of the fiber patch cord industry?
With the acceleration of 5G, data centers and FTTH (fiber to the home) construction, the industry presents two major trends:

Miniaturization: The proportion of LC/MPO interfaces has increased, but ST is still in demand in the stock market;

High density: Ningbo Goshining Communication launched a 1U 48-core ST patch panel, which increases space utilization by 40% compared with traditional solutions.

What are the core competitiveness of Ningbo Goshining Communication?
Integration of the entire industry chain: from optical fiber preform drawing to jumper assembly, achieving dual control of cost and quality;
Quick response capability: regular orders are delivered within 3 days, and urgent orders are processed within 24 hours;
Global service network: products are exported to more than 30 countries including Europe, America, Southeast Asia, etc., providing multi-language technical support.
