Straight answers.

A low-voltage contractor installs the cabling and systems that run below 50 volts: structured network cabling (Cat6/Cat6A and fiber), communications rooms and racks, conference room displays and video conferencing, security cameras, wireless networks, and telecom circuits. JDP Communications is a licensed California low-voltage contractor (CSLB #1061737) serving commercial buildings across Southern California.

Yes. JDP Communications LLC is a licensed California low-voltage contractor, CSLB #1061737, in business since 2005.

Cat6 handles 1 Gbps at full distance and 10 Gbps up to about 55 meters; Cat6A handles 10 Gbps at the full 100 meters and supports high-power PoE with less heat. For new commercial construction we usually recommend Cat6A. The labor is the same and the cable outlives the tenants.

A common baseline is two data drops per workstation plus drops for Wi-Fi access points, printers, cameras, and conference rooms. We walk the site and count with you before anything is quoted.

Every run is certified with a Fluke tester against the TIA-568 standard: wire map, length, insertion loss, NEXT and return loss. You receive labeled test reports for 100% of installed cables.

Common causes: failed or partial terminations, runs longer than 100 meters, damaged pairs, or copper-clad aluminum (CCA) cable that can't carry the load. A certification test identifies the failure in minutes. Then we fix the physical cause and re-test.

Wire map, length, insertion loss, NEXT (crosstalk), and return loss against the TIA-568 standard. A link either passes or fails. No opinions, just a report.

Yes. We certify existing installations and deliver labeled reports, commonly used for tenant improvements, building purchases, and disputes over whether cabling meets spec.

Yes. Live-environment work is planned in phases with after-hours cutovers, so production systems stay up while racks, backbone, and power go in.

Yes: OM4 multimode and single-mode, terminated, polished, and tested. Backbone is sized with spare strands so the room scales without another pull.

Labeled racks and panels, port maps, and Fluke certification reports for 100% of installed links. That is the paper trail that makes the room maintainable.

It's the cabling that carries your carrier's circuit from the building's MPOE (where the provider's responsibility ends) to your suite or server room. The carrier won't build it. A licensed low-voltage contractor does.

Yes. That phrase means the fault is between the MPOE and your equipment, our side of the line. We test the extension, find the fault, and repair or re-pull it.

Yes. We coordinate with the carrier's technician, have the extension ready before they arrive, and verify the handoff end-to-end so the cutover happens once.

The MDF (main distribution frame) is the building's primary communications room where carrier circuits land and the network core lives. IDFs (intermediate distribution frames) are smaller closets on each floor or wing that feed nearby drops and uplink back to the MDF over fiber.

Yes. Rack cleanups and re-dressing are common projects: we re-route, re-dress, re-label, and re-test existing cabling, usually after hours so your network stays up during business hours.

Yes. We install UPS units and distributed power in the rack, sized to your equipment load, so switches and critical gear ride through short outages.

Both. We pull and certify the cabling, mount the displays, install the cameras, speakers, and microphones, and set the room up so it joins a call on the first try.

Yes. We build the room around the platform you already use, so the hardware, the room controller, and the calendar all line up with how your team actually books and joins meetings.

We coordinate power with a licensed electrical contractor so the outlets, the display locations, and the floor boxes are all set before finish work closes the walls.

It depends on square footage, construction materials, and device density; a site survey answers it precisely. We design from the survey so you buy the right number of APs, not the safe-sounding number.

Dead zones are usually a coverage and cabling problem, not a device problem. Access points placed by guess, or fed by a drop that never passed a test, fail in the same spots every time. A survey and a certified drop fix both.

Yes. For big footprints (warehouses, campuses, parking structures) we design coverage from a survey and use point-to-point links where running cable between buildings is not practical.

Both. We pull and certify the cabling, mount and aim the cameras, set up the recorder, and hand you a labeled, documented system.

We standardize on UniFi Protect, so the cameras, the recorder, and the network are one system managed from one place.

That comes from a site walk. We go through the building with you, mark the entries, lots, and areas that matter, and count cameras and cable runs before anything is quoted.
