Accelerating Fiber Rollouts with Pre-terminated Solutions
Securing site access and power forms the foundation of in-building DAS deployments, enabling signal distribution without disruptions.
Securing site access and power forms the foundation of in-building DAS deployments, enabling signal distribution without disruptions. Multi-tenant buildings require approvals from owners, tenants, and utilities. Field teams navigate these to achieve site readiness and sustained operations.
Access coordination spans risers, ceilings, and rooftops. Property managers control master keys and schedules.
Tenant consents cover antenna placements in leased spaces. Review leases for RF easement clauses.
Union labor rules apply in commercial high-rises. Coordinate with IBEW for structured cabling.
Elevator use demands priority slots. Freight cars handle equipment pallets up to 5,000 lbs.
24/7 buildings require after-hours notifications. Security escorts prevent unauthorized entry.
Riser closets house head-ends. Secure dedicated space with 42U racks and 48-strand fiber termination.
Pathway approvals verify fire-rated enclosures. Maintain 2-hour ratings per IBC Section 712.
Ceiling plenum access needs lift certifications. Sequence around HVAC commissioning.
Drilling approvals for floor penetrations. Core sizes match sleeve diameters per design.
Construction sequencing prioritizes risers pre-drywall. Sleeve all shafts early.
DAS head-ends draw 1-5 kW based on capacity. Remote units add 50-200W each via PoE.
Utility service upgrades assess panel capacity. 100A dedicated feeds support multi-operator neutral host.
Subpanel installs in telco rooms. Breakers sized to NEC 240.21 for continuous loads.
Grounding busbars bond to building steel. #2/0 AWG mains per TIA-607.
Backup generators sync to UPS for 15-minute bridges. Diesel runtime targets 4 hours.
Site readiness confirms voltage stability: 208/480V three-phase common.
Surge protection at entries
Hybrid fiber/PoE cabling powers low-output remotes. Cat6a supports 100m runs at 90W.
DC plants consolidate feeds. -48V rails distribute to floors.
Fiber remote power via DC over fiber converters. Eliminates copper runs.
Verify drops with multimeters pre-population.
Electrical permits cover all tie-ins. AHJs enforce NEC 2023 updates.
Fire marshal reviews pathway penetrations. Intumescent collars seal around cables.
Structural engineering stamps rooftop mounts. Windload per ASCE 7.
RF exposure filings if EIRP exceeds limits. Model per OET 65.
Safety compliance mandates MSDS for batteries. Spill containment in rooms.
Celnet works alongside deployment partners to sequence access. Pre-stage gear in staging areas.
Lockout/tagout protocols for hot work. Verify zero voltage before fiber pulls.
Access logs track personnel. RFID badges integrate with building systems.
Construction managers align DAS with MEP rough-ins. Avoid clashes in risers.
Quality control audits pathway fills under 40% per TIA-569.
Lift plans detail rigging for rooftop head-ends. Crane certifications current.
Master service agreements outline scopes. Indemnity covers install damages.
Tenant walkthroughs confirm placements. Adjust for aesthetics like concealed antennas.
Utility coordination schedules meter installs. CT cabinets for high-draw sites.
Ongoing access post-deploy via service level agreements.
Commissioning tests continuity. Megger risers at 1kV DC.
Load bank trials simulate peak draw. Monitor voltage sag under 5%.
UPS transfer seamless within 10ms. Battery capacity discharge tests.
DAS power alarms tie to BMS. SNMP for remote monitoring.
Closeout packages include single-line diagrams and panel schedules.
As-builts map access points and power panels. Include photos of terminations.
O&M manuals detail breaker locations and lock codes.
Handover meetings review access protocols with facilities.
Spare parts lists cover fuses and PoE modules.
Celnet supports site access and power for DAS projects.
