Detailed explanation of pre-connected OM4 fiber distribution frame

　　First, OM4 fiber optic distribution frame foundation analysis

　　Definition and characteristics

　　High bandwidth support: OM4 fiber is designed for short-distance, high-bandwidth tranSMission, supporting up to 100Gbps (commonly used 40Gbps), with a bandwidth of 4700 MHz · km, far exceeding OM3's 2000. MHz · km.

　　Transmission distance: At 40Gbps, the transmission distance can reach 100 meters; at 10Gbps, it can be extended to 550 meters, suitable for high-density cabling in data centers.

　　Compatibility: Compatible with existing OM3/OM2 network devices, but attention needs to be paid to upgrading network devices to give full play to their performance.

　　Application scenarios: Widely used in high-bandwidth scenarios such as data centers, enterprise networks, and local area networks (LANs).

　　Technical core

　　50/125μm core: Laser diode light source is used to optimize signal transmission efficiency.

　　Low loss characteristics: Signal attenuation is lower than OM3, ensuring long-distance transmission stability.

　　Standardization: Complies with IEC 60798-1-4 international standards to support future network upgrades.

　　Second, the advantages of pre-connected OM4 fiber optic distribution frames

　　rapid deployment

　　Factory pre-welding: Fiber optic jumpers are welded and connected in the factory, without secondary operation on site, shortening the installation cycle by more than 50%.

　　Plug and Play: The modular design supports rapid capacity expansion and adapts to the dynamic requirements of the data center.

　　performance assurance

　　Link quality: Factory pre-testing ensures that the insertion loss is < 0.3dB, which is better than the average 0.5dB loss of field welding.

　　High-density support: Supports MPO/MTP connectors, and single-ended ports can integrate 12-24-core optical fibers to improve space utilization.

　　Easy to maintain

　　Visual label: Port identification is clear and supports electronic label scanning management.

　　Fault location: Built-in smart sensors can monitor the link status in real time, reducing the time to fault location to minutes.

　　III. Key steps of installation and configuration

　　Environmental preparation

　　Space requirements: reserve ≥ 600mm of operating space to ensure ventilation and dryness.

　　Tool list: fiber cutter, fusion splicer, OTDR tester, label printer.

　　installation process

　　Fixed distribution frame: calibrated with a level, the error is less than or equal to 1mm/m.

　　Cable introduction: Bending radius ≥ 15 times the cable diameter to avoid signal loss.

　　Pre-splice module docking: insert pre-splice jumpers according to port number to ensure correct polarity.

　　Testing and Acceptance

　　Link test: Use an optical power meter to measure losses (≤ 1.5dB), and OTDR detects reflection points.

　　Documentation: Generate wiring lists and test reports to support subsequent maintenance.

　　IV. Future development trends

　　Technical direction

　　UHF support: Adapted to 800G transmission requirements, supports PAM4 modulation technology.

　　Photoelectric fusion: Integrated power distribution unit (PDU), simplifying the wiring of the computer room.

　　AI operations: Predicting link failures through machine learning for preventive maintenance.

　　market forecast

　　Growth rate: It is expected that from 2025 to 2030, the compound annual growth rate of the pre-connected OM4 distribution frame market will exceed 15%.

　　Application scenario expansion: Extend to 5G base stations and Internet of Things edge computing nodes.

　　V. Selection Suggestions

　　Data center: Preference is given to high-density products that support MPO/MTP (such as Zhongtian Technology ZTT series).

　　Enterprise Networks: Focus on modular designs (e.g. Hengtong HTGD-OM4-Pre) for phased expansion.

　　Industrial environment: Consider anti-electromagnetic interference models (e.g. Tongding TD-OM4-Flex).

　　With the pre-connected OM4 fiber optic distribution frame, users can ensure high performance while significantly reducing construction complexity and post-maintenance costs, making it a key infrastructure for building future-ready networks.
