View DetailsLessons from Our Mistakes
The 2022 Istanbul Metro Vibration Failure
A critical signaling link in the Istanbul Metro failed after 14 months of operation.
Standard ABS trays were used in an environment with constant 15-20Hz vibration. The splice sleeves 'rattled' inside the holders, causing micro-fractures at the fusion point.
Redesigned the tray with 'Soft-Grip' TPE (Thermoplastic Elastomer) sleeve holders that absorb vibration.
Zero failures in 2,500+ trays deployed in high-vibration transit zones since 2022 (Tracking: TR-IST-METRO-2022).
Core Lesson:Static lab tests don't account for the dynamic stress of urban infrastructure.
The 'Chemical Fog' Degradation (2021 Coastal Plant)
Splice trays in a petrochemical facility became brittle and cracked after 2 years.
The standard ABS plastic reacted with airborne sulfur compounds, reducing impact strength by 60%.
Switched to a chemically resistant PBT/PC alloy for industrial-grade trays.
Extended service life to 10+ years in corrosive environments (Tracking: IND-CHEM-2021).
Core Lesson:Material selection must account for atmospheric chemistry, not just temperature.
Industry Reality Check
The 'Invisible' 2dB Loss
"Our 2022 field audit (sample: 1,200 splice trays in older ODFs) found that 18.5% of high-loss links were caused by 'slack congestion'—where too much fiber was forced into a tray without proper mandrels. This creates micro-bends that are invisible to the eye but add up to 2.2dB of loss across a link. Telhua's 'slack-management' zones eliminate this congestion risk (Source: 2022 Infrastructure Integrity Audit, Tracking: INFRA-INT-2022)."

When NOT to Choose This Product
Aerial 'mid-span' splices without a closure
Splice trays have zero IP rating; they are purely for internal management within a protective housing.
Recommendation
Always house splice trays inside an IP68-rated FOSC for outdoor aerial or underground use.
Installation Protocol
Splice Tray Fiber Management
Secure the tray onto the FOSC or ODF mounting stud.
Route the incoming buffer tubes to the tray entry, securing with cable ties.
Splice the fibers and heat-shrink the protection sleeves.
Press the sleeves into the 'Soft-Grip' holders (listen for the click).
Coil the fiber slack into the figure-8 loops to ensure >30mm radius.
Engineering & Deployment FAQs
How does Telhua manage 'micro-bend' risks in high-density 48-core trays?
Through precision-molded radius mandrels and specialized fiber crossover paths.
Why do some plastic trays become brittle and snap after 5 years?
The use of recycled ABS without plasticizers leads to loss of ductility over time.
Is it better to use 12-core or 24-core splice trays?
12-core is safer for maintenance; 24-core is better for density.
