Flexible HDMI Cabling Solutions for In‑Conduit Routing & Pull‑Through Installation
Traditional copper HDMI cables feature bulky HDMI connectors, which frequently get stuck inside narrow conduits during pull‑through installation.
OPTAV delivers three optimized fiber‑based HDMI options to resolve tight‑tube wiring pain points: detachable‑head HDMI AOC, MPO‑based detachable HDMI extender and LC-based HDMI extender with pigtail.
Our modular design lets installers route slim bare fiber first, then attach signal conversion hardware on‑site, simplifying conduit, in‑wall and ceiling deployment for Pro‑AV projects.
Project Pain Points for Conduit HDMI Deployment
Standard copper HDMI cables come with large‑size molded HDMI plugs. These rigid connectors cannot pass through small‑diameter conduits, limiting routing options for renovation, new‑build and retrofit AV deployments. Even many off‑the‑shelf fiber‑HDMI AOC still have non‑removable HDMI metal heads, creating the same pull‑through bottleneck.
OPTAV provides two core wiring philosophies to address this issue:
Detachable‑head AOC solution: Separate HDMI connector assemblies from fiber cable body. Only the slim fiber section is pulled through the conduit; connectors are snapped on after cable routing is complete.
Pre‑installed pure‑fiber infrastructure solution: Run passive MPO / LC fiber cables through conduits in advance. After fiber cabling is finished, plug in OPTAV HDMI extenders to bring up HDMI video signal. No active electronics inside the routed fiber run.

Core Advantages of OPTAV Conduit‑Friendly HDMI Fiber Solutions
- ✅ Slim‑profile pull‑through capability
Only thin fiber cable passes through narrow conduits. Bulky HDMI connectors stay outside tubing, eliminating jamming risks during cable pulling.
- ✅ Two flexible deployment modes for different project workflows
Choose detachable‑head AOC for fast all‑in‑one deployment; or leverage pre‑laid MPO / LC passive fiber for structured cabling projects.
- ✅ Uncompressed lossless video transmission
Support full‑bandwidth 4K /8K HDMI signal, preserve YUV4:4:4, HDR metadata and embedded audio without compression artifacts.
- ✅ Future‑proof structured cabling
For MPO / LC pre‑wired projects, fiber infrastructure stays untouched during hardware upgrade or replacement. Swap extenders without re‑pulling cables.
- ✅ Simplified on‑site installation & maintenance
Fiber pulling work completes before connecting active hardware. Faulty transceiver modules can be replaced without re‑routing conduit cabling.
- ✅ EMI‑immune fiber performance
Immune to electromagnetic interference for long‑distance in‑wall / conduit runs.
🔹 Detachable‑head HDMI AOC
Detachable‑head AOC splits the fiber cable body and HDMI active connector ends. During installation, remove HDMI plug assemblies, pull only slim fiber through conduits. Once fiber is routed into position, lock back the HDMI‑AOC heads. Ready‑to‑use end‑to‑end HDMI fiber cable, no extra equipment required.
Best for：Retrofit projects, short‑to‑mid distance runs, projects without pre‑installed fiber.
🔹 MPO‑based Detachable HDMI Extender
Pure‑fiber structured‑cabling workflow. Installers first run passive MPO multi‑mode fiber through conduits / wall ducts. After completing fiber termination, attach OPTAV MPO HDMI extender transceivers onto pre‑installed MPO fiber links. All active signal conversion sits outside the conduit. Fiber infrastructure remains fully passive inside tubing.
Best for：New‑construction structured AV cabling, long‑run conduit layout, future‑proof AV rooms.
🔹4K Octopus Series
Pigtail‑style HDMI fiber extender. Small‑form‑factor transceiver modules with flying fiber pigtails. Pull thin pigtail fiber through conduit, then mount the transceiver box at source/display side. Works with standard LC terminated fiber links.
Best for：4K uncompressed AV extension, limited cabinet space, point‑to‑point LC‑fiber deployments.

Frequently Asked Questions
Q1：What is the key benefit of detachable‑head AOC for conduit pull‑through?
A：It removes bulky HDMI metal connectors before pulling. Only slim fiber cable passes through narrow conduits. Connectors are re‑attached after cabling is finished.
Q2：Can I use pre‑existing site MPO / LC fiber with OPTAV extenders?
A：Yes. For MPO‑based HDMI extender and Octopus series, you may pre‑install passive MPO or LC fiber through conduits first, then connect OPTAV transceivers once fiber work is completed. No active electronics inside conduit.
Q3：Do these solutions support uncompressed HDMI video?
A：Yes, HDMI AOC and MPO-based fiber extender support umcompressed native HDMI signal, zero compression, lossless image quality. Both compressed and uncompressed options available for LC‑based fiber video transmission.
