The ABB TK811V150 is a specialized industrial-grade duplex plastic optical fiber engineered for reliable short-distance optical communication in ABB automation systems—specifically optimized for ABB S800 I/O architectures, 800xA DCS, and AC800M PLCs requiring cost-effective, EMI-immune data transmission. It functions as a "duplex optical link," enabling bidirectional data transfer between modules, termination units, and control cabinets through two parallel plastic optical fibers (POF), while offering flexibility, durability, and easy handling in industrial environments. Designed for indoor, short-range applications, it provides an alternative to glass fiber in scenarios where frequent bending, low installation complexity, and cost efficiency are prioritized. Below is its detailed specification:
- Product Model: TK811V150
- Product Series: ABB TK Series Plastic Optical Fibers (Duplex Industrial Optical Communication)
- Core Function: Enables bidirectional optical data transmission between ABB automation components; provides EMI-immune communication in short-distance applications; connects modules, racks, and control cabinets in harsh industrial environments; ensures compatibility with ABB optical ports (e.g., TB811)
- Optical & Transmission Specifications:
- Environmental Ratings:
- Operating Temperature Range: -20℃~+70℃ (-4℉~158℉)
- Storage Temperature Range: -40℃~+85℃ (-40℉~185℉)
- Humidity Tolerance: 5%~95% RH (non-condensing, 40℃)
- Chemical Resistance: Resistant to mineral oils, dilute acids, and industrial detergents (per IEC 60068-2-54)
- Vibration Resistance: 10~500Hz, 1g acceleration (no fiber breakage or signal loss)
- Compliance Standards: CE, RoHS, ABB Optical Communication Standard V2.1, IEC 61032 (accessibility), UL 94 V0 (flame retardancy)
- Duplex Bidirectional Communication: Two parallel POFs enable simultaneous transmit/receive functionality—supports full-duplex data exchange between ABB components (e.g., S800 I/O rack to remote terminal unit), eliminating the need for separate transmit/receive cables.
- EMI-Immune Transmission: Plastic optical fiber is inherently immune to electromagnetic interference—ideal for installation near high-noise equipment (e.g., motor drives, transformers) in factories, where copper cables suffer from signal corruption.
- Large 1mm Core Diameter: Simplifies connector alignment during installation—reduces termination errors by 40% compared to glass fiber (0.25mm core), making it suitable for field technicians without specialized fiber training.
- Flexible & Durable Design: 25mm static bending radius and PVC jacket withstands frequent handling and bending—resists breakage during cabinet reconfiguration or maintenance, unlike fragile glass fiber which requires careful handling.
- Cost-Effective Optical Solution: Lower material and installation costs than glass fiber—provides an economical EMI-immune alternative for short-range applications (≤100m), such as within control cabinets or between adjacent cabinets.
- Plug-and-Play ABB Compatibility: Proprietary push-pull connectors integrate seamlessly with ABB optical ports (e.g., TB811) and I/O components—requires no polishing or epoxy, enabling quick installation and replacement.
- Flame-Retardant Jacket (UL 94 V0): Meets industrial fire safety standards—reduces fire spread risk in control cabinets, complying with building codes for electrical enclosures in manufacturing facilities.
- ABB Automation System Internal Communication: Primary application in short-range optical links:
- Control Cabinet Interconnections: Connects S800 I/O modules to optical ports (TB811) within the same cabinet or adjacent cabinets (≤50m); EMI immunity prevents interference from nearby power supplies and motor drives.
- 800xA DCS Local Expansion: Links a local expansion rack to the main 800xA controller via 30m duplex POF—cost-effective alternative to glass fiber for short distances, with easier installation for plant technicians.
- High-Noise Industrial Environments: EMI-immune communication near heavy machinery:
- Automotive Factory Robot Cells: Transmits signals between robot controllers and S800 I/O modules (≤20m) in noisy welding cells—eliminates EMI from welding equipment that corrupts copper-based communications.
- Steel Mill Control Rooms: Connects temperature monitoring modules to AC800M PLCs (≤50m) near rolling mills—POF’s noise immunity ensures accurate temperature data transmission for process control.
- Indoor Industrial Wiring: Flexible installation in constrained spaces:
- Food Processing Line Controls: Routes optical signals (≤30m) between washdown-rated enclosures and main control cabinets—PVC jacket resists caustic cleaners, while flexibility simplifies routing around equipment.
- Pharmaceutical Cleanrooms: Connects sterile process sensors to 800xA DCS (≤40m) in Class 8 cleanrooms—smooth jacket design minimizes particle accumulation, complying with GMP standards for hygiene.
- Retrofit & Upgrade Projects: Cost-effective EMI solutions for legacy systems:
- Chemical Plant Legacy Upgrades: Replaces copper bus cables with 50m POF links between existing PLCs and new S800 I/O modules—eliminates ground loops that plagued copper connections, reducing unplanned downtime by 25%.
- Water Treatment Plant SCADA Links: Connects remote I/O terminals to central SCADA (≤100m) via POF—costs 30% less than glass fiber while providing EMI immunity from pump motors.
- Distance & Data Rate Limitations (Critical): Do not exceed 100m at 10Mbps or 50m at 100Mbps—longer distances cause signal attenuation (>15dB), leading to communication errors; verify distance requirements before installation.
- Installation & Handling Safety:
- Bending Radius Compliance: Maintain minimum bending radius (25mm static, 50mm dynamic)—excessive bending (e.g., <15mm) crushes the fiber core, increasing attenuation by ≥10dB/km and causing data loss.
- Connector Alignment: Ensure connectors are fully seated with a positive "click"—partial insertion causes signal loss (>3dB) and intermittent communication; avoid twisting connectors during mating.
- Fiber Cutting: Use ABB-recommended POF cutters (part no. 1SFA898001R1000)—dull or improper tools create jagged ends, increasing insertion loss; trim fibers perpendicular to the axis for optimal light transmission.
- Operation & Maintenance:
- Contamination Prevention: Keep connector ends clean—dust or oil on surfaces reduces light transmission by ≥50%; clean with lint-free wipes and isopropyl alcohol (do not use water).
- Visual Inspection: Check quarterly for:
- Jacket damage (cuts, abrasions from sharp edges)
- Loose connectors (common after vibration)
- Kinks in the fiber (causes permanent attenuation)
Replace damaged sections immediately—exposed fiber is vulnerable to moisture and mechanical stress.
- Environmental Protection: Avoid direct contact with chemicals beyond the resistance range (e.g., strong acids, ketones)—use protective conduit in areas with chemical exposure; PVC jacket resists mild substances only.
- Environmental Limitations:
- Temperature Constraints: Do not operate below -20℃ or above +70℃—cold temperatures make POF brittle, while high temperatures (>70℃) soften the core, increasing attenuation; use thermal insulation in extreme zones.
- UV Exposure: Avoid prolonged direct sunlight—UV radiation degrades PMMA core over time, increasing attenuation; route fibers through opaque conduits in outdoor or UV-exposed areas.
- Replacement & Spare Parts:
- Genuine ABB Components: Use only genuine TK811V150 fibers and ABB connectors—non-genuine POF has inconsistent core dimensions and higher attenuation, leading to communication failures with ABB optical ports.
- Spare Inventory: Maintain 2~3 spare fibers (50m and 100m lengths) per 10 optical links—fiber damage disconnects critical communication; spares reduce downtime from 3+ days (custom order) to <1 hour for mission-critical systems
