OM1/2 광섬유 패치 코드

OM1/OM2 multimode fiber patch cord industry knowledge analysis
I. Product core features and classification
1. Why are OM1/OM2 patch cords called "traditional multimode fiber"?
OM1 (core diameter 62.5μm) and OM2 (core diameter 50μm) are early multimode fiber standards, using LED light sources, and full injection bandwidths of 200/500MHz·km and 500/500MHz·km in the 850nm band. Ningbo Goshining Communication Technology Co., Ltd. strictly follows ISO/IEC standards when producing such products. Its OM1 patch cord can support 300 meters of 1Gbps transmission, and OM2 patch cord can support 550 meters of 1Gbps transmission, which is suitable for short-distance local area networks (LANs) and internal wiring in buildings.

2. How to quickly distinguish OM1/OM2 patch cords by color?
According to industry specifications, OM1 patch cords usually use orange sheaths, while OM2 patch cords are mainly gray or black sheaths. Ningbo Goshining Communication Technology Co., Ltd. not only follows this international practice in product design, but also uses beige or black logos on the connector protective sleeves for quick identification on site. For example, its FC/UPC-FC/UPC-OM1-2D2M model jumpers use an orange sheath and a blue FC connector to achieve both visual and functional distinction.

2. Technological evolution and industry pain points

3. Does the rise of OM3/OM4 mean that OM1/OM2 will be eliminated?
Although OM3 (laser optimized 50μm) and OM4 (enhanced laser optimized) perform better in 10G/40G/100G transmission, OM1/OM2 still has cost advantages. Ningbo Goshining Communication Technology Co., Ltd. has reduced the unit length cost of OM2 jumpers by 30% by optimizing the production process, making it still competitive in scenarios below 1Gbps. For example, in a data center renovation project, the customer used Ningbo Goshining's OM2 patch cord to replace OM3, which saved 42% of the wiring cost while meeting the 550-meter transmission requirement.

4. How to solve the signal attenuation problem of OM1/OM2 patch cords in a curved environment?

The bending loss of multimode optical fiber is an industry problem. Ningbo Goshining Communication Technology Co., Ltd. optimized the minimum bending radius of its OM2 patch cord from 10 times the fiber diameter to 7.5 times the fiber diameter by using low-bending-sensitivity coating materials. Laboratory tests show that at a 30mm bending radius, the additional loss of its products is 0.15dB lower than the industry standard, effectively improving wiring flexibility.

III. Application Scenarios and Selection Guide

5. How to choose OM1/OM2 and single-mode optical fiber within a distance of 100 meters?

Although single-mode optical fiber supports longer distances, the cost of 1310nm band optical modules is 2-3 times that of 850nm multimode modules. Ningbo Goshining Communication Technology Co., Ltd. recommends: within 100 meters and when the transmission rate is ≤1Gbps, OM2 patch cords are preferred; if it is possible to upgrade to 10Gbps in the future, OM3 patch cords can be pre-deployed. For example, one of its corporate customers uses a hybrid solution of OM2+OM3 in office building wiring, which not only meets current needs but also reserves space for future upgrades.

6. Why do data centers still use a large number of OM1/OM2 patch cords?
Although new data centers tend to use OM4, OM1/OM2 is highly favored in the transformation of the existing market due to its strong compatibility and low cost. Ningbo Goshining Communication Technology Co., Ltd. helps customers reduce 30% of redundant wiring by providing customized services, such as precisely cutting the length of OM2 patch cords to 0.5-meter increments. A case study of a bank data center transformation showed that after using Ningbo Goshining's customized OM2 patch cords, the cabinet space utilization rate increased by 15% and the wiring efficiency increased by 40%.

4. Ningbo Goshining Communication Technology Co., Ltd.'s core advantages
7. How to achieve full-chain quality control from R&D to delivery?
The company has passed ISO9001:2015 and ISO14001:2015 dual certifications and established 12 quality control nodes from raw material detection to finished product aging. For example, its OM2 jumper needs to go through the following during the production process:

Fiber core diameter laser scanning detection (error ≤±0.5μm)
850nm band insertion loss test (≤0.3dB/km)
-40℃~+85℃ high temperature and high humidity cycle aging (1000 hours)
8. Faced with customized needs, how to balance efficiency and cost?
Ningbo Goshining Communication Technology Co., Ltd. shortens the jumper customization cycle to 3 days through a modular design platform. For example, a customer needs an OM1 patch cord with a length of 1.2 meters, a 0.9mm sleeve, and an LC/APC connector. The company completed sample delivery in just 48 hours by calling the standard component library, which is 60% shorter than the industry average cycle.

V. Industry Trends and Challenges
9. Will the popularity of OM5 optical fiber impact the OM1/OM2 market?
OM5 supports SWDM technology and can achieve 4-wavelength parallel transmission, but its current cost is 1.8 times that of OM4. Ningbo Goshining Communication Technology Co., Ltd. believes that between 2025 and 2030, OM1/OM2 will still occupy more than 60% of the market share of short-distance cabling, especially in cost-sensitive fields such as security monitoring and industrial automation.

10. How to deal with the price war in the fiber patch cord industry?
Ningbo Goshining Communication Technology Co., Ltd. maintains the proportion of R&D investment at more than 8% through the technology premium strategy, focusing on the development of high value-added products. For example, its radiation-resistant OM2 patch cord can work stably in strong electromagnetic environments such as nuclear power plants through special coating materials. Although its unit price is 35% higher than that of ordinary products, it still receives long-term orders from customers such as CGN.

Ningbo Goshining Communication Technology Co., Ltd. continues to maintain its technological leadership in the field of OM1/OM2 patch cords by relying on its full industrial chain layout, strict quality control system and customized service capabilities. Its products not only cover traditional application scenarios, but also meet the needs of emerging fields such as 5G and data centers through innovative designs, providing global customers with cost-effective optical communication solutions.
