Copper I&R Technician
The Copper Installation and Repair technician handles the legacy twisted pair plant from the central office or remote terminal out to the customer premises. Day to day work includes new service installs, drop replacements, NID work, inside wiring, jack installs, and trouble isolation on POTS, DSL, and alarm circuits. They locate and repair faults like opens, shorts, grounds, crosses, and battery crosses using a TDR, butt set, toner, and a basic transmission tester. Comfortable working aerial off a ladder or bucket, in pedestals and B boxes, and in crawlspaces and basements. Expected to read cable counts, work binder groups, splice modular and encapsulated closures on smaller pair counts, and follow assignment from the LFACS or equivalent OSP records. Typical background is two plus years with an ILEC or telecom contractor, OSHA 10, climbing and aerial lift certifications, and a clean MVR.
Fiber I&R Technician
The Fiber Installation and Repair technician installs and repairs single mode fiber from the OLT or hub down through the distribution and drop network to the ONT at the customer premises. Core skills include placing and securing drop cable, prepping and splicing with a fusion splicer, terminating with field installable connectors or pre terminated assemblies, and testing with a power meter, light source, VFL, and OTDR. They install and provision ONTs, often in basements or near the electrical panel in Fidium territory, hand off Ethernet or coax to the customer router, and verify service activation with the NOC. Strong candidates can read a GPON design print, identify splitters and FDH ports, troubleshoot high loss and reflectance issues from an OTDR trace, and clean and inspect connectors with a scope every time. Typical background is one plus years of FTTH or FTTx field work, fusion splicing experience, ladder and lift certifications, OSHA 10, and a clean MVR. BICSI, FOA CFOT, or carrier specific certifications are a plus.
Central Office Technician
The Central Office tech, sometimes called a COT or CO installer, works inside the carrier's central offices, huts, and CEVs rather than at customer locations. Responsibilities include equipment installs and removals, frame work on the MDF and DSX, power and ground per Telcordia GR 1089 and GR 295, cable rack and ladder builds, fiber and copper riser cabling, and turn up of OLTs, DSLAMs, MSAPs, optical transport gear, and channel banks. They follow method of procedure documents, work hot and cold cuts during maintenance windows, and are expected to leave the office cleaner than they found it. Strong candidates know negative 48 volt DC plant, understand alarm extension and office wiring practices, can read CLLI codes and equipment grounding diagrams, and have hands on time with at least one major OEM platform such as Calix, Adtran, Nokia, Ciena, or Fujitsu. Typical background is three plus years CO or central office installer work under TL 9000 or BICSI standards, with strong documentation habits and the ability to pass carrier specific badging and background checks.
Circuits I&R Technician (Special Circuits)
The Circuits I&R tech is the modern descendant of the Bell System special circuits role. They install, test, and repair dedicated and engineered services that are not plain residential broadband, including DS1, DS3, MetroE, EVPL, EPL, dedicated internet access, point to point fiber, business voice trunks, and legacy private lines and alarm circuits. They work to a circuit layout record or design layout, hit specific transmission objectives, and prove out circuits end to end with the carrier NOC. Expected fluency includes loss and noise measurement, BERT testing on T1 and Ethernet, RFC 2544 and Y.1564 service activation testing, light level verification on optical handoffs, and signaling validation on voice trunks. Strong candidates can read a CLR, identify equipment at each office in the path, isolate trouble to a specific span or shelf, and document results in carrier portals. Typical background is three plus years on special services, business services, or carrier wholesale work, with a transmission test set and Ethernet tester in their hand on a regular basis. Highly skilled candidates are scarce and command higher rates than standard I&R.
Air Pressure Technician
The Air Pressure tech maintains the pressurized cable system that keeps moisture out of older lead and PIC copper plant. They monitor and service the dryer plants in central offices, manifolds and pressure transducers in the field, and the alarm and monitoring systems that flag leaks. Daily work includes leak locating with sonic and tracer gas equipment, repairing sheath damage, replacing transducers, recharging desiccant towers, calibrating pressure and flow alarms, and updating cable pressure records. They read pressure contour maps, understand flow versus static pressure, and know how a leak in one section shows up at sensors blocks away. Strong candidates have specific air pressure or cable pressurization experience, often from an ILEC career, since the skill set is uncommon and not transferable from generic OSP work. Typical background is five plus years OSP copper experience with at least two years in a dedicated pressure role. This is the smallest and hardest to source category on the list.
CPE/911/PBX Technician
The CPE, 911, and PBX tech works at the customer premises on terminal equipment rather than the access network. Scope covers PBX and key system installs, moves, adds, and changes on platforms like Avaya, Mitel, NEC, and Cisco, hosted and SIP trunk cutovers, station cabling and cross connects on 66 and 110 blocks, analog and digital station sets, paging and door entry systems, and 911 specific work including ALI database updates, ELIN provisioning, Kari's Law and RAY BAUM compliance verification, and PSAP testing coordination. Strong candidates can program a dial plan, troubleshoot a SIP trunk with a packet capture, read a riser diagram, and walk a customer through a cutover with minimal downtime. 911 work in particular requires careful documentation since errors have life safety consequences. Typical background is three plus years voice or unified communications field work, manufacturer certifications on at least one major PBX or UC platform, BICSI Installer 1 or 2 a plus, and comfort working in commercial environments including hospitals, schools, and government sites that often require additional background screening.
