Description
Pre-Terminated Optical + Electrical Hybrid Cable for FTTR (Optical Power Composite Cable) — SC/UPC Hybrid or XC/UPC
If you’re deploying FTTR (Fiber-to-the-Room) and need a cleaner, faster way to connect room terminals/APs with both signal and low-voltage power, this is the cable we recommend.
AimiFiber’s Optical + Electrical Hybrid Cable (also called optical power composite cable) combines G.657A2 bend-insensitive fiber with integrated copper conductors in one compact jacket, then factory pre-terminates the ends for consistent optical performance and reliable power delivery.
It is widely used in FTTR low-voltage indoor wiring, where installers want a standardized “one-cable” solution that avoids messy parallel runs and reduces on-site termination work.
Why this hybrid cable is used in FTTR projects
Most FTTR retrofit sites have the same constraints:
- Homeowners demand clean aesthetics (no trunking, no exposed power lines).
- Installers want speed and repeatability across many rooms.
- Integrators need stable optical performance and predictable power delivery.
With a hybrid cable, you route one cable instead of separate fiber + power, and you avoid variability caused by field termination.
Key benefits (what your target buyer cares about)
1) One run for signal + power
- Fiber link (G.657A2) + copper conductors in the same cable
- Cleaner routing, fewer installation steps, easier maintenance
2) Factory pre-terminated, consistent quality
- Controlled termination conditions
- Every assembly can be tested before shipment (optical + electrical)
3) Built for tight indoor routing
- Bend-insensitive fiber supports complex indoor paths (corners, frames, concealed routes)
- Compact OD helps keep wiring discreet
4) More predictable power design
- Multiple conductor cross-sections are available so you can match distance vs load
- Helps reduce voltage drop risk in multi-room FTTR layouts
Typical FTTR use cases
- Room-level FTTR terminals / mini-ONUs
- Room AP backhaul + low-voltage power distribution
- MDUs / apartments / hotel rooms where fast standardized deployment matters
- Retrofits where drilling and conduit work must be minimized
Product options (choose the structure that matches your project)
We typically supply three structural styles depending on routing and handling preferences:
| Cable Type | Outer Dimension (Typical) | Fiber | Copper Conductor (Typical) | Jacket | Notes |
|---|---|---|---|---|---|
| Flat Composite Cable (recommended for indoor routing) | ~ 4.2 × 1.8 mm (customizable) | G.657A2 | 0.13 mm² (branch) / other options | LSZH (common) | Easy to route along edges; clean indoor look |
| Round Composite Cable (often used as “trunk”) | ~ 4.3 mm OD | G.657A2 | 0.52 mm² (trunk) / other options | LSZH (common) | Better for longer distance / higher power loads |
| Butterfly Composite Cable | ~ 4.4 × 2.0 mm | G.657A2 | 0.32 mm² (typical) | LSZH (common) | Balanced option for specific routing preferences |
Fiber interface (standard): SC/UPC, SC/UPC (Hybrid), XC/UPC
OEM options: SC/APC, LC/UPC, customized hybrid connector formats (project-based)
Practical recommendation: in FTTR projects, we usually define a “trunk + branch” concept—use larger conductor for trunk runs, then branch into rooms with smaller, more flexible flat cable.

Engineering note (important for serious buyers): distance vs voltage drop
In FTTR low-voltage distribution, the main constraint is usually voltage drop over distance, not optical loss.
That’s why trunk runs often use larger conductor area (example: 0.52 mm²), and branches use smaller flexible sizes.
If you tell us:
- target voltage (typical low-voltage systems),
- device power consumption (W),
- cable run length (m),
we can help you select a conductor size that keeps terminal voltage within an acceptable range.
Installation guidance (field-friendly)
- Route the cable first, then connect—avoid pulling directly on the connector body.
- Keep bends smooth; avoid sharp pinching at corners.
- Maintain clean connector endfaces; inspect/clean before mating.
- For trunk/branch designs: label each branch length to reduce troubleshooting time later.
- Verify power polarity and continuity before final device connection.
What we test before shipment (quality you can prove)
As a direct manufacturer, we control quality from cable materials to termination and assembly. Typical outgoing checks include:
- 100% optical IL test on terminated ends
- Return loss verification per connector type (UPC/APC)
- DC continuity + insulation check
- Visual inspection for jacket integrity and connector protection
Test reports and labeling can be provided for project deliveries and OEM lots.

FAQ
Q1: Is this cable “PoE”?
No. PoE is Ethernet over copper. This is an optical + power composite cable for FTTR-style optical networks where you want fiber signal + low-voltage power in one run.
Q2: Why not just run fiber and power separately?
You can—but on real sites that usually means:
- more labor,
- messier routing,
- more failure points,
- harder maintenance.
Hybrid cable standardizes installs and improves consistency in multi-room rollouts.
Q3: Which connector should I choose: SC/UPC or SC/APC?
For hybrid FTTR indoor networks, SC/UPC is common.
If your network design requires APC (reflection-sensitive scenarios), SC/APC can be supplied as an OEM option.
Q4: How do I choose conductor size?
It depends on distance and load.
As a rule: longer distance / higher power → larger conductor area. Share your layout and device power, and we’ll recommend a safe configuration.
Q5: Can you supply trunk + branch pre-planned assemblies?
Yes. Many FTTR projects use standardized trunk/branch kits to speed up multi-room deployment and reduce on-site mistakes.
