Detailed description

The FULLAXS-DLC/UPC Single Mode Duplex Fiber Patch Cord, 30m with black LSZH jacket, is specially designed for long-distance outdoor FTTA fiber-to-the-antenna connections. Its primary application is a 30-meter connection between base stations and remote radio units such as RRU, BBU, RRH, or antenna-side equipment.

The key selling points include G.657A1 bend-insensitive fiber, a 5.0mm thick reinforced jacket, black LSZH safety sheathing, and reliable 30m remote deployment capability. G.657A1 fiber offers a minimum bend radius of up to 7.5mm, providing better bend resistance than traditional G.652D fiber with an approximate 30mm bend radius. This helps maintain stable signal transmission in high-density cabling environments.

The 5.0mm outer jacket contains an aramid yarn strength member and an optional steel wire armor layer, significantly improving tensile strength, abrasion resistance, and impact protection. The black jacket material also enhances UV aging resistance for outdoor use.

The LSZH, or Low Smoke Zero Halogen, jacket produces almost no toxic smoke or corrosive gases in the event of fire, helping improve equipment and personnel safety.

The FULLAXS connector system meets IP67/IP68 waterproof requirements and supports drag-and-drop panel-side installation. Its one-hand plug-and-unplug operation provides clear connection feedback, making it suitable for harsh outdoor environments.

Key Product Advantages

Technical Description

G.657A1 fiber characteristics:

This patch cord adopts ultra-low bend-sensitive single mode fiber compliant with the ITU-T G.657A1 standard. Its operating wavelength range covers 1260–1625 nm and is compatible with common 1310/1550 nm communication systems. G.657A1 fiber improves micro-bending loss performance through optimized core doping and coating processes, allowing a minimum bending radius of 7.5 mm without affecting signal transmission. This makes it highly suitable for dense cabling and corner-routing scenarios, such as concealed cable trays in equipment rooms, tower routing, and compact outdoor installation paths. Compared with traditional G.652D fiber, G.657A1 can withstand tighter bending with less additional attenuation, giving installers greater flexibility in limited spaces.

5.0mm reinforced jacket material and structure:

The patch cord adopts a 5.0mm outer diameter structure, with an aramid yarn, Kevlar, strength layer and an optional central armored stainless steel tube to improve mechanical strength and tensile performance. The tight-buffered fiber is coated with flame-retardant material to form a protected fiber unit. Multiple strands of Kevlar yarn are added around the fiber to increase tensile strength, while some configurations can also include a spiral metal layer to improve compression resistance and rodent protection. The outer jacket is made of a specially formulated black LSZH thermoplastic material. After UV stabilization treatment, it offers excellent weather resistance and can operate for long periods within a wide temperature range of -40°C to +85°C. Compared with common 2.0–3.0mm thin patch cords, the 5.0mm thick jacket provides higher tensile load capacity and better physical protection, helping prevent fiber breakage and external mechanical damage.

LSZH safety performance:

Low Smoke Zero Halogen, or LSZH, material does not contain halogen elements such as fluorine, chlorine, or bromine, and generates significantly less smoke and corrosive gas during combustion. In the event of accidental fire or high-temperature exposure, this patch cord releases only a very small amount of acidic gas, reducing the risk of toxic smoke damage to personnel and equipment. Therefore, it is suitable for applications requiring higher fire safety and environmental protection standards.

Black outdoor weather resistance:

The black outer jacket is enhanced with carbon black and UV-resistant additives to improve light stability and withstand long-term direct sunlight exposure. Similar to common outdoor network cable designs, the black jacket helps absorb UV energy and reduces material cracking and aging. Combined with resistance to high and low temperatures, water, and ozone, this black LSZH jacket is suitable for outdoor tower-top, pole-line, rooftop, and building-wall installation environments.

Performance Indicators and Testing References

Tensile strength:
Based on the structural design, this patch cord can achieve approximately 1000N short-term tensile strength and 600N long-term load-bearing capacity. Tensile verification is usually performed according to IEC 60794-1 for optical cable mechanical performance and GR-20 general requirements for outdoor telecom cables. In actual use, it is recommended to reserve a safety margin of more than 25% below the rated tensile load to protect the fiber.

Bend-insensitive performance:
With G.657A1 fiber, the cable can withstand very small bends, with a 7.5mm radius, without significant attenuation. Testing is based on the macro-bending loss measurement defined by ITU-T G.657. Typical results show no increase in insertion loss when the bending radius is above 10mm. Compared with G.652D fiber, which has a minimum bending radius of approximately 30mm, this patch cord provides nearly negligible bend loss in compact routing environments.

Weather and UV resistance:
The outer jacket material passes environmental tests such as IEC 60068-2 temperature cycling and damp heat testing, with an operating temperature range of -40°C to +85°C. UV aging tests can also be performed according to IEC 61300-2-9 to verify physical performance stability after outdoor UV exposure. The weather resistance of black LSZH is similar to professional outdoor cable materials, offering excellent resistance to UV radiation, moisture, and heat.

Insertion loss and return loss:
Fiber optic connectors are commonly evaluated according to the IEC 61300 series and Telcordia GR-326 test standards for insertion loss and return loss performance. This patch cord uses LC/UPC connectors, with typical insertion loss ≤0.30 dB, meeting or exceeding the industry requirement of 0.5 dB, and return loss ≥50 dB. Quality verification can be carried out using IEC 61300-3-34 for end-face inspection and IEC 61300-3-6 for insertion loss testing.

Protection rating:
The FullAXS connector system provides IP67-level sealing performance, meeting dustproof and waterproof requirements. Testing can refer to the IEC 60529 IPX7 water immersion test. Reliable technical references indicate that the TE FullAXS connector design can reach IP68 water resistance, while also offering lightning resistance and UL94-V0 flame-retardant performance. The complete assembly is validated under harsh environmental conditions to ensure stable outdoor operation.

Competitive Comparison

The FULLAXS-DLC/UPC 30m patch cord offers clear advantages over common G.652D indoor patch cords in bend resistance, tensile strength, and fire safety. At the same time, it also incorporates part of the outdoor durability advantages commonly associated with PE-jacketed cables.

Compared with 3.0mm or smaller-diameter patch cords, this product features a stronger 5.0mm reinforced structure, providing better durability for outdoor FTTA deployment. Compared with PE outdoor cables, it offers a higher safety level in fire-sensitive environments, with low-smoke and zero-halogen performance designed to reduce toxic smoke and corrosive gas emissions during combustion.
