CableForge: Low Voltage Tools

CableForge is the all-in-one field toolkit for low-voltage and structured-cabling technicians. 22 pro tools for data, network, security, AV, fiber, and power — every reference table and calculator you reach for on a job, in one fast, offline app.

Built by trade, for trade. No clutter, no logins, no internet required — just the numbers you need, on the truck or in the ceiling.

WHAT'S INSIDE — 22 TOOLS
━━━━━━━━━━━━━━━━━━━━

DATA CABLING
• T568A / T568B RJ45 pinouts — color-accurate wiring for jacks, plugs & patch panels
• Cat cable specs — Cat5e, Cat6, Cat6A, Cat7, Cat8 bandwidth & distance
• Run-length limits — copper, HDMI & AV distances at a glance

NETWORK & PoE
• IP subnet calculator — CIDR, subnet mask, network, broadcast & usable hosts
• PoE reference — 802.3af / at / bt power classes
• PoE loss calculator — voltage at the device over any gauge and run

SECURITY & SURVEILLANCE
• Camera storage calculator — size an NVR by cameras, bitrate & retention
• Camera lens & pixel density — field of view, angle & DORI (detect/observe/recognize/identify)
• Alarm zones & EOL — supervised loops and end-of-line resistor values
• Access control — maglocks vs strikes, REX, Wiegand & OSDP wiring

AUDIO / VIDEO
• Speaker impedance — series / parallel loads
• 70V / 100V constant-voltage — distributed audio tap budgets
• Projector throw — mounting distance from throw ratio & screen size
• Coax & HD-over-coax — RG59 / RG6 distances for TVI/CVI/AHD

VOICE & TELECOM
• 25-pair color code — telco binder group order

FIBER
• Fiber color code — 12-strand order & fiber types
• Fiber loss budget — optical loss vs link budget

POWER
• Voltage drop calculator — DC device runs, AWG-aware
• Battery standby — backup runtime & sizing for alarm/access panels

INSTALL & PATHWAYS
• Conduit fill — EMT fill % against NEC limits
• Bend radius & pull tension — cable-safe install limits

SOUND MASKING
• Design guide — levels, spacing & tuning

WHY CABLEFORGE
━━━━━━━━━━━━━━━━━━━━
• 100% offline — works in basements, ceilings, and dead zones
• Fast, dark, high-contrast UI built for the job site
• No account, no sign-up, no data collection
• One low-voltage app instead of ten single-purpose calculators

WHO IT'S FOR
Structured cabling installers, low-voltage electricians, CCTV & security integrators, network cable techs, AV installers, fiber technicians, fire/life-safety and access-control pros, and apprentices studying the trade.

Reference values follow TIA-568, TIA-598, IEEE 802.3 and NEC where applicable. Always verify against the AHJ, manufacturer specs and current code.
