Description
What Makes This Cable Different
Most patch cords focus only on optical performance.
This one is built for optical performance plus survivability.
The APC (Angled Physical Contact) ferrules minimize back reflection, making the cable ideal for 1550 nm laser systems, RF-over-fiber, and high-power optical transmission.
The armoured layer protects the fiber against pulling, bending, rodent bites, and installation damage — a major advantage for outdoor or industrial deployment.
Meanwhile, the FC threaded connector ensures the ferrule stays locked in place, preventing micro-movement that can degrade signal quality over time.

Where This Cable Is Used
-
FTTx & telecom central offices
-
CATV & RF-over-fiber networks
-
Outdoor base stations
-
Railway and industrial communication systems
-
Military, broadcast, and security networks
The combination of APC polishing + armoured construction makes it especially suitable for long-haul and high-power optical links where reflection and physical damage must be minimized.
Why APC Matters in High-Performance Networks
Unlike UPC connectors, APC ferrules are polished at an 8-degree angle, forcing reflected light into the fiber cladding instead of back into the laser. This reduces:
-
Optical noise
-
Laser instability
-
Bit-error rate (BER)
With return loss ≥ 60 dB, APC connectors are the standard for CATV, PON, and RF-over-fiber systems.
Engineered for Harsh Environments
The armoured structure adds:
-
Crush resistance
-
Rodent protection
-
High tensile strength
-
Better bending durability
This allows the cable to be routed through cable trays, outdoor ducts, and industrial enclosures without the fragility of standard patch cords.
Professional Q&A
Q1: Can FC/APC connectors be used with UPC ports?
No. APC and UPC must never be mixed — doing so can damage connectors and severely degrade performance.
Q2: Why is this cable ideal for CATV and RF-over-fiber?
Because APC connectors provide ultra-low back reflection, which is critical for analog and RF optical signals.
Q3: What advantage does the armoured cable provide?
It protects the fiber against crushing, pulling, rodents, and harsh installation environments, making it ideal for outdoor and industrial use.
Q4: Is this cable suitable for 10G and PON systems?
Yes. It fully supports 10G, GPON, XG-PON, XGS-PON, and RF-over-fiber networks.
