Product Introduction
The GJFJU (TPU) Round Drop Fiber Optic Cable is a specialized cable for "last-mile" FTTH/FTTx networks. It is designed for installations where space is tight and durability is key, bridging outdoor and indoor environments.
Why Choose TPU Sheath?
The "TPU" in the name is a crucial feature. Compared to standard PVC or PE jackets, TPU offers:
Superior Durability: It is highly resistant to abrasion, UV radiation, moisture, and extreme temperatures, which ensures a long lifespan of over 25 years in harsh conditions.
Excellent Flexibility: The cable remains flexible, allowing for easy routing around tight corners and through conduit without cracking.
Enhanced Safety: TPU is a halogen-free material that emits low smoke in a fire, making it a safer choice for residential and public spaces.
Versions & Options
The GJFJU cable comes in several configurations:
Fiber Count: Available from 1 to 12 fibers or more, with each fiber enclosed in a 0.9mm tight buffer for protection. Some specifications mention fiber counts up to 24.
Attenuation: For single-mode fibers like G.657, the maximum attenuation is typically ≤0.35 dB/km at 1310nm and ≤0.20 dB/km at 1550nm.
Bend Radius: With G.657B3 bend-insensitive fiber, the cable can handle very tight bends (as small as 5mm radius), minimizing signal loss in confined spaces.
Applications
✔ Given these features, the GJFJU (TPU) cable is ideal for:
✔ Last Mile Connections: As a drop cable running from a distribution point to a home or business (FTTH/FTTx).
✔ Indoor/Outdoor Transitions: It can be routed directly from an outdoor aerial or buried plant into a building, as its jacket meets both outdoor weather and indoor fire safety requirements.
✔ Space-Constrained Pathways: Its small diameter makes it perfect for installation in crowded conduits or micro-ducts using cable blowing techniques.
✔ Robust Environments: Its durable TPU sheath makes it suitable for industrial applications, direct burial, and short-span aerial installations where it may be exposed to the elements.
