Internal modification of the ward network is a typical scenario where all-optical networks are introduced into the hospital: nurse calls, infusion alarms, and mobile ward rounds are all burdened on floor switches, making the old architecture strenuous. Optical fiber to the bedside is suitable for POL flat networking, but hospital construction regulations are stricter. Please arrange the bandwidth, construction and wiring before starting.
Bandwidth and business isolation
Video calls, infusion data and ward round terminals can share the PON port, but it is recommended that critical areas and ordinary areas have separate light splitting groups, and life support related services should not compete with other systems for the same set of fiber cores and light splitting boxes. The design usually leaves a 3dB light-absorbing margin for each point, and the ONU light-absorbing baseline is filed by room to facilitate future comparison. The active points of the all-optical network are concentrated in the computer room and room ONU, and the floor splitter box is passive. The UPS only needs to cover both ends, and the call and HIS channels can be maintained during a short power outage.
Three things to know about hospital construction
- Work in divided periods: do the unmanned side during the day and the manned side at night. Processes that generate dust and noise should avoid the rest period.
- The jumpers are pre-assembled at the factory and are only plugged and unplugged on site, not welded or cleaned in the ward.
- Bedside open section selectionSingle-mode single-core armored jumpers, anti-mouse jumper pigtails, special jumpers for Internet cafes, special jumpers for cabinets, the metal sheath prevents pulling and collision with the wheelchair.
Wiring and safeguarding of old equipment such as calls
Many ward calls and door screens use the RS485 bus, and it is not recommended to use the new trunk; it is available2-way bidirectional RS485 data optical terminalBy extending the bus along with the optical fiber, the original host wiring remains unchanged, the parallel operation of the new and old systems is more stable, and the bottom line business during power outages is easier to maintain.
