more efficiently, as all cables are part of a unified system. This holistic approach reduces complexity, making it easier to troubleshoot, maintain, and upgrade the network as and when needed. FUTURE-PROOF CONCEPT Make sure to choose cabling that supports today’s high-speed data rates and offers capacity to handle future increases, while maintaining low latency and high signal integrity. This is particularly important for applications requiring real-time data transmission such as VOIP and video conferencing. Using high- quality hybrid cabling can enhance the overall performance of the network by providing higher bandwidth and faster data transmission speeds while vastly simplifying rollout, upgrades, and changes to how a building is used. The digital ceiling approach can also enhance the aesthetic appeal of a workspace by hiding cables and devices within the ceiling, while also allowing for functional benefits like easier access for upgrades and repairs. Overall, a hybrid cabling concept brings significant advantages in terms of cost, efficiency, performance, and future readiness, making it an ideal solution for modern LAN environments. When specifying and installing a future-proof hybrid cabling system, several key factors need to be considered to ensure the system meets current needs while remaining adaptable for future
technological advancements. In addition to the fibre port and one corresponding RJ45 for power distribution, we recommend including extra RJ45 based 10Gbps (Cat.6A) connections on each service outlet for legacy devices. Ideally, solutions should be designed for quick and secure installations and offer robust, quick termination solutions. You’ll also need to ensure the cabling system complies with relevant industry standards such as ANSI/TIA-568, ISO/IEC 11801, and IEEE standards for PoE and high-speed ethernet (10G, 40G, 100G). We strongly recommend performing certification testing after installation to verify the system’s performance and standards compliance.
Existing cabling infrastructures with service outlets and zone distributors can be very easily expanded with the required number of fibre ports. The digital ceiling approach is highly modular, allowing easy addition or removal of devices without the need for significant re-cabling. This flexibility supports scalability as network demands grow. Long-term savings from reduced maintenance, ease of upgrades, and lower power consumption can make this approach more cost-effective over time compared to relying on pre-assembled patch cords. Remote powering of terminal equipment is typically supplied via RJ45 connections, the same as with PoE. Existing LAN cabling can cover distances of up to 90 metres of Permanent Link when used for this purpose. For longer transmission distances, thicker conductors (for example AWG 16) must be used. These are laid parallel to the fibre cables, often laid within a common jacket. At both ends of such hybrid FO / Power cables, a specially designed RJ45 jack is needed to distribute the power from the two wires to the 8 pins of the RJ45. The digital ceiling solution can accommodate permanent links of up to 200 m. This hybrid cabling in the Digital Ceiling approach also allows network administrators to manage and monitor the entire network infrastructure
