Control room projects in utilities and transportation now routinely specify 32 or more operator positions, each requiring 4K60 video, USB 2.0 HID, and serial control from distant server racks. Traditional KVM extenders, such as single-link fiber pairs from Adder or older Black Box models, deploy one transmitter-receiver set per workstation. At this count the cable plant alone reaches 64 fiber strands plus 32 dedicated power drops, pushing material and labor line items above $185,000 before any switching layer is added.
IHSE Draco matrices consolidate those links through a central 64-port or 128-port chassis using Draco tera extenders on the user side and Draco ultra transmitters at source racks. The matrix handles EDID management, lossless compression, and 1+1 fiber redundancy inside one 4RU frame. Integrators report the chassis plus 64 extender endpoints lands near $142,000 list, with single-mode fiber trunks reduced to 16 strands via CWDM muxes. The delta appears in installation hours: two technicians terminate and test the trunk bundle in one day rather than running individual home runs across multiple conduits.
Port Density and Cabling Realities
Draco port licensing requires careful counting. Each user station consumes one input and one output port; sources consume only inputs. At 32 stations with 48 sources the design sits comfortably inside a 128-port frame yet leaves 48 spare ports for future expansion. Traditional extenders carry no port licensing but also no native ability to route any source to any station without an additional layer of matrix hardware, which then duplicates the Draco topology at higher per-port cost. Power draw favors the matrix as well: a fully populated Draco chassis pulls 380 W while 32 separate extender pairs average 640 W once local PSUs and cooling fans are totaled.
Workflow changes surface during rack elevation and labeling. With point-to-point extenders every transmitter needs its own fiber patch field and UPS outlet, lengthening rack elevation drawings and creating 32 individual maintenance tickets. The Draco approach collapses source termination to two high-density fiber cassettes feeding the matrix rear, so label sets shrink and the integrator can pre-stage the entire matrix in the shop before truck roll. On-site commissioning then focuses on assigning user rights via the Draco tera management software rather than tracing individual strands.
Service contracts reflect the topology difference. A traditional layout triggers truck rolls to individual workstations when a single fiber fails; Draco diagnostics surface the fault at the matrix SNMP trap, allowing remote port disable until the next scheduled visit. One Midwest systems house logged 14 service events across three 32-station rooms over 18 months and attributed 11 of them to the consolidated matrix approach cutting mean-time-to-repair by roughly half.
Looking ahead, rising 8K preview workflows and mandatory AES67 audio embedding will pressure both architectures. Draco already supports 8K single-frame rates on its latest extender cards, while most legacy point-to-point sets remain capped at 4K60. Integrators evaluating bids today increasingly model a five-year refresh cycle that factors in card swaps rather than full re-cabling when pixel counts climb again.
Integrators also cite improved cybersecurity posture. Because all user stations connect through a single managed matrix rather than scattered point-to-point links, IT teams can enforce 802.1X port authentication, segment traffic on isolated VLANs, and push firmware updates from one console. Traditional extender pairs often leave transmitters exposed on the network with minimal authentication, creating potential entry points that must be hardened individually. In regulated environments such as NERC CIP or TSA pipeline standards, the consolidated audit trail generated by Draco tera software reduces compliance documentation time by an estimated 30 hours per project.
Another overlooked line item is spare-parts inventory. A 32-station point-to-point fleet typically requires eight to ten hot spares of each extender model plus multiple PSU variants, tying up roughly $18,000 in shelf stock. A Draco installation needs only two spare extender cards and a single redundant power supply module, cutting that reserve investment by more than half while still covering the most common failure modes.
Finally, operator training curves flatten. With sources routed through familiar on-screen display or API calls rather than memorized fiber mappings, new hires reach full proficiency in two days instead of two weeks. Several control-room managers report that this reduction in ramp-up time alone offsets the matrix premium within the first year of operation.
