Full Guide on Product Selection & Industry Compliance Standards

In low-voltage engineering, telecom infrastructure, campus construction and data center projects, the selection of outdoor optical cables plays a decisive role. Improper cable selection will lead to high rework costs, project acceptance obstacles and heavy long-term maintenance burdens.

 

Nowadays, loose-tube optical cables feature outstanding stability and reliability, and fully comply with China national standard YD/T 901-2018. They have been widely adopted to serve over 90% of outdoor backbone links and become the mainstream solution for such scenarios.

 

With more than 30 years of in-depth experience in the communication industry, Zhaolong Interconnect is a leading domestic supplier of digital communication cables and systematic solutions. We provide mature loose-tube optical cable products and tailored solutions, delivering solid, stable and high-performance connectivity for all outdoor backbone transmission applications.

 

 

What Is Loose-Tube Optical Cable?

Simply put, a loose-tube optical cable is structured with multiple loose tubes stranded around a central strength member. It adopts precisely controlled fiber excess length design, delivering superior physical protection and excellent mechanical properties.

 

Specially engineered for long-haul, high-bandwidth transmission under harsh outdoor operating conditions, it is also the standard mainstream structure specified in YD/T 901-2018 for outdoor communication optical cables.

 

Systematic Structure Design Delivers All-Round Protection

Our loose-tube optical cables are built with optimized systematic design, fully satisfying strict requirements on outdoor backbone links in terms of protection performance, operational reliability and long-term service stability. Core advantages are listed as below:

 

1. Full Cross-section Water-blocking Design

The cable core is fully filled with high-performance water-blocking compound to achieve complete waterproof and moistureproof effect, effectively isolating rainwater and humid air for stable long-term outdoor operation.

 

2. High-strength Mechanical Resistance

Equipped with metallic or non-metallic central strength members, the cable boasts excellent tensile strength and crush resistance, ensuring stable performance for aerial laying, direct burial and duct installation.

3. High-precision Loose Tube Protection

Premium PBT and modified PP/PC loose tubes are adopted to fully shield optical fibers, effectively avoiding fiber breakage caused by bending and extrusion, and guaranteeing consistent and stable signal transmission.

 

4. Complete Fiber Count Specification

Available in full fiber counts ranging from 4 cores to 288 cores, perfectly meeting demands from small-capacity access networking to large-capacity backbone data transmission.
