All links were available during acceptance inspection. However, after expansion three years later, it was found that the spare core had no terminals, the idle ports had no labels, and the rack slots were all filled. The value of reservation design lies in making reservations truly usable: accessible, accessible, and affordable.
Core layer: spare cores will be put on the shelves first
Spare cores should be melted and pigtailed in the splicing box, led to the ODF distribution frame for installation, and core number labels should be attached, instead of being coiled in the box; when the ends are completed, they should be plated in the order of core numbers, and the labels can be checked on both sides, so it is not easy to connect incorrectly during night shift construction. The core that has been put on the shelf can be used by inserting a jumper when expanding the capacity, for exampleLC-LC single mode dual core jumperThis kind of commonly used specifications; the remaining length is neatly coiled in the fiber coiling area, and the bending radius is left enough to prevent it from breaking in the box when being used in the future.
Port layer: Idle ports must also have ledgers
- Dust cap for idle optical port cover, ledger registration number and reserved purpose
- One or two module spare parts are prepared according to the distance range, and the spare parts are continuously available in case of emergency.
- Jumpers are reserved in proportion to the ports in use, usually one for every four live ports.
- Any changes on the client side will be written back to the ledger on the same day to avoid a disconnect between the actual account and the actual account.
Slot layer: leaving power supply and space for the future
When placing the box transceiver on the rack at a location with many box transceivers, select14-slot box transceiver rackFor this type of specifications, two-thirds of the slots are installed first, and the remaining slots are reserved for the next phase of ports. The empty slots are installed with false panels to keep out dust. For centralized power supply racks, the power supply margin is calculated based on the full slot diameter, not the current number of slots. The location of the distribution frame should also leave vertical space for the ODF expansion unit.
Three-tier reservations follow the same principle: only reservations that can be verified are reservations. Before EB-LINK technical support issues a configuration list, it usually requires photos and accounts of the existing network endpoint. If you need a template, please dial 0755-83179002.
