Key points for end acceptance of optical fiber between weak currents: solution label and excess length

Key points for acceptance of optical fiber ends between weak currents: plan, label and excess length

In the building tenant access project, the weak current room is the centralized point for optical cable termination and jumper placement. The quality of the termination directly determines the speed of tenant changes and troubleshooting in the future. Before delivery, it is recommended to check the plan, label, and remaining length one by one.

The end-to-end solution first checks the core number, port number, and room number.

The end-to-end solution requires a one-to-one correspondence between the trunk core number, weak current room port number and tenant room number. The format is recommended to be written as segment A 12 cores, floors 1-6, port 01, room 601. SC port jumpers are commonly used on the tenant end and the end, such asSC-SC single mode single core jumper, maintaining the same type of adapter and pigtail end faces will increase insertion loss.

Labels need to withstand five years of changes

The space between weak currents is narrow and the humidity is variable. Inkjet labels are easy to blur. Use an oil-based pen for handwriting. It is recommended to use tie-type labels instead of adhesive for machine-made labels. Each label contains at least local and remote information. When starting a new project, pressCampus network and FTTH integrated cabling solutionThe standardized and unified template is much less labor-intensive than having to rework after the tenants move in.

Yu Chang has enough left now and will have to make two fewer trips in the future.

Reserve one to two meters on the end side for the fiber splicing tray, and the bending radius is generally not less than 30mm.
Keep at least one spare jumper on each layer, and the length should be one step higher than the current specification.
The splicing loss is recorded core by core. A single point is usually controlled below 0.2dB. If it exceeds the standard, it will be reworked on the spot.

These three things are all extra items at the construction site, but they cannot be omitted during acceptance inspection. EB-LINK's end-end jumpers and adapters can be supplied according to the same set of marking specifications, and the handover documents are kept clean, so that the labor required for tenant changes in the future can be reduced to minutes.
