Description
The Aimit Hybrid Fiber-Copper Composite Cable is an integrated solution designed for FTTA (Fiber to the Antenna) and remote power applications. By combining optical fibers for data and copper conductors for power in a single robust jacket, it reduces installation time and cabling costs for 5G Base Stations, RRUs (Remote Radio Units), and Security Cameras.

Designed for North American Standards:
Available with 12 AWG, 14 AWG, 16 AWG copper conductors to meet NEC standards for remote power distribution.
Key Technical Advantages
- One Cable, Two Functions: Simultaneous transmission of high-bandwidth data and low-voltage power (DC 48V/60V).
- Structure Options:
- Standard: Stranded structure for flexibility.
- Armored: With Steel Tape (PSP) or Steel Wire (SWA) for direct burial and rodent protection.
- Copper Conductors: High-purity Oxygen-Free Copper (OFC) ensures low resistance and stable power delivery over long distances.
- Jacket Material: UV-resistant PE (Outdoor) or LSZH (Indoor/Riser).
Applications (FTTA & DAS)
This hybrid cable is specifically engineered for:
- 5G/4G Mobile Towers: Connecting BBU (Base Band Unit) to RRU (Remote Radio Unit).
- Smart City Infrastructure: Powering remote Wi-Fi APs and CCTV cameras without local power sources.
- DAS (Distributed Antenna Systems): In-building signal coverage.

A single hybrid trunk that combines optical transmission and DC power distribution for last-mile active equipment. Typical builds include a tight-buffer fiber sub-cable (e.g., 2F G.657A2) plus copper power conductors within a UV-resistant black sheath; shielding (Al/PET foil) and a tinned-copper drain wire are available to simplify grounding. Cross-sections and parameters are shown in the reference drawings and datasheets.
Where it’s used
- 5G/4G FTTA to Remote Radio Heads (RRH), small cells, rooftop BTS
- DAS and repeater systems in stadiums, tunnels, and venues
- Pole-mounted and perimeter CCTV/PTZ cameras, wireless bridges, IoT gateways
- Long outdoor runs to shelters and cabinets (duct, tray, or aerial with hardware)
Why it helps
- 2-in-1 cable plant: one pull and one BOM cut power + fiber deployment time dramatically.
- Long-reach power: choose copper gauge to match run length and load; typical rated voltage 400/600 V on 12 AWG assemblies.
- Bend-tolerant fiber: G.657A2 sub-cables maintain low loss even in tight routing.
- Outdoor-ready: UV-resistant PE outer sheath; shield + drain wire options for robust EMI control.

Configurations & Options
- Fiber count: 2F, 4F, 6F, 8F, 12F (OS2; OM3/OM4 on request).
- Copper gauge: 2×14–12 AWG, 3×16 AWG, or project-specific mm² equivalents (e.g., 2×2.5 mm², 2×4 mm²).
- Armor: unarmored; spiral-armored fiber sub-units; or overall steel/aluminum tape (GYTS/GYTA) for rodent resistance.

- Terminations: bulk reels; factory pre-terminated breakouts (e.g., LC duplex uniboots to equipment tails) with labeled power pairs and length tolerances.
- Sheath: outdoor PE (UV), or LSZH for indoor sections.
Key Benefits
- Single-pull deployment: data + DC power in one cable reduces labor and tray space.
- Long-reach powering: selectable AWG/area supports higher current and lower voltage drop to RRHs and cameras.
- Tight-buffer optics for fast terminations: low IL connectors with stable RL.
- Outdoor durability: UV sheath, shield/drain, and optional armor for rodent-prone routes.
- Pre-terminated trunks: reduce site splice/connector time; consistent breakout lengths and tolerances.
Ordering Information (example code)
HFC–[Fxx]–[OS2/OMx]–[P2×14AWG or P3×16AWG]–[Shield Y/N]–[Armor N/Spiral/GYTS/GYTA]–[Sheath PE/LSZH]–L[Length]
Example: HFC–F12–OS2–P2×14AWG–ShieldY–Spiral–PE–L300 m.
Include load (W), distance (m), and system voltage at RFQ so we calculate gauge and voltage-drop headroom.
FAQ
Q1. How do I select the copper gauge?
We size AWG/mm² to your device current and run length to keep voltage drop within the OEM limit. Provide device wattage and system voltage; 12 AWG is common for long-run RRH trunks.
Q2. Can the cable be installed outdoors and then enter a building?
Yes. Use UV-resistant PE for the outside section; transition to LSZH or specify an LSZH overall where code requires.
Q3. Do you offer shield and drain wire?
Yes—Al/PET foil with a tinned-copper drain wire for simplified grounding.
Q4. What fiber types are available?
OS2 G.657A2 is standard for bend tolerance; OM3/OM4 on request.
Q5. Can you factory-terminate fibers and pre-cut power tails?
Yes—pre-terminated LC/UPC uniboots and labeled power leads with defined breakout lengths/tolerances are available.
