For high - speed data center transmission scenarios, we recommend two types of our fiber products. The first is multi - mode fiber (MMF) with OM3 and OM4 specifications. These two types of multi - mode fibers support high - speed transmission protocols such as 10Gbps, 40Gbps, and 100Gbps, and their transmission distance (up to 400m for OM4) can fully cover the short - distance connection needs between servers, switches, and storage devices in data centers. The second is low - loss single - mode fiber (SMF) that complies with the ITU - T G.657 standard. This type of single - mode fiber has lower attenuation and better bending resistance, which is suitable for long - distance interconnection between different data center buildings (with a transmission distance of up to 10km) and can meet the requirements of large - scale data center cluster networking. Both types of products have passed strict compatibility tests with mainstream data center equipment, ensuring stable and efficient data transmission.

We use different jacket materials for indoor and outdoor fiber products based on their usage environments. For indoor fiber products, we mainly adopt PVC (Polyvinyl Chloride) and LSZH (Low Smoke Zero Halogen) materials. PVC jackets have good flexibility and cost - effectiveness, making them suitable for general indoor wiring scenarios; LSZH jackets are non - toxic and produce low smoke when burned, which is more in line with the safety requirements of public places such as hospitals and shopping malls. For outdoor fiber products, we use PE (Polyethylene) and ARMOR - coated materials. PE jackets have excellent weather resistance and corrosion resistance, capable of withstanding rain, ultraviolet radiation, and other outdoor environmental factors; ARMOR - coated jackets (usually made of steel or aluminum tape) add mechanical protection, effectively preventing damage from external impacts, rodent bites, and other risks, ensuring the stability of outdoor long - term use.

Yes, our fiber products fully support customization of fiber count to meet the diverse needs of different application scenarios. For common standard fiber cables (such as telecom and LAN - used fibers), the fiber count range is usually 1 to 144 cores. For special - purpose fibers like medical or industrial - grade fibers, the fiber count can be adjusted according to specific device requirements, ranging from 1 core (for single - channel precise transmission) to 72 cores (for multi - channel integrated transmission). When customizing, our technical team will also provide professional suggestions based on the customer's application environment and transmission demands.

In our product line, there is a clear difference in core diameter between single-mode fiber (SMF) and multi-mode fiber (MMF). The core diameter of single-mode fiber is relatively small, usually fixed at 9μm, which allows only one light mode to propagate during transmission. In contrast, the core diameter of multi-mode fiber is larger, with two common specifications: 50μm and 62.5μm. This larger core enables multiple light modes to transmit simultaneously, which is the key structural difference between the two types of fibers.

We mainly provide four core types of fiber products. The first is Telecom Fiber, which serves as the core transmission medium for high-speed and reliable communication networks, supporting large-capacity data transmission over long distances. The second is Medical Fiber, featuring high precision and stable light transmission, specifically designed for medical devices such as endoscopes and diagnostic equipment to ensure accurate signal transmission. The third is Laser Fiber, specialized in high-power and high-brightness laser energy delivery, with excellent heat resistance and energy-conducting performance, suitable for laser processing and medical laser treatments. The fourth is Illumination Fiber, enabling safe non-electric light transmission, free from electric shock risks, and widely used in architectural decorative lighting and underground engineering lighting.
