Fiber Optic OTDR Launch Cable Box SC/APC-SC/UPC SM 1km

This high-performance OTDR Launch Cable Box, often referred to as a “Pulse Suppressor,” is an indispensable professional tool for fiber optic certification and troubleshooting. By providing a 1km length of premium G.650 Single-Mode fiber between the OTDR and the Link Under Test (LUT), it allows the OTDR’s optics to stabilize, effectively eliminating the “Dead Zone” caused by the initial high-power pulse. This ensures that the first connector in your network is fully visible and accurately measured. The internal fiber is wound with precision tension control to maintain a signal attenuation of less than 0.35 dB/km, ensuring that your trace data remains clean and reflective of true network performance.

The unit is housed in a ruggedized, high-density polyethylene shell that is waterproof, dust-proof, and impact-resistant, making it suitable for the most demanding outside plant (OSP) environments. Unlike inferior models, our launch boxes utilize a continuous, splice-free fiber strand to prevent internal reflections that could ghost your OTDR traces.

• Splice-Free Fiber Path: Features a single, continuous 1000-meter strand of fiber for zero-interference signal transmission.

• Hybrid Connector Configuration: Pre-terminated with high-quality SC/APC (Green) and SC/UPC (Blue) connectors to bridge different network interfaces.

• Environmental Resilience: Engineered to be explosion-proof and dirt-resistant with an IP-rated protective casing for field reliability.

• Optimized Dead Zone Compensation: The 1km length is specifically calculated to provide ample suppression for long-haul and metro network testing.

• Integrated Pressure Valve: Features an auto-purge valve to balance internal pressure, preventing the box from sealing shut due to altitude or temperature changes.

• Compact & Portable: Lightweight design with a built-in carabiner/strap attachment for easy transport up ladders or into manholes.

• Link Characterization: Essential for technicians needing to measure the insertion loss and reflectance of the near-end connection.

• FTTH/PON Deployment: Ideal for testing residential fiber drops where precision in short-range measurements is critical.

• Emergency Restoration: Quickly identify the exact location of a break near the central office or local hub.

• Network Auditing: Used by Tier-2 certification teams to provide documented proof of fiber span integrity for service level agreements (SLAs).

• During maintenance, the launch box acts as a protective buffer, preventing the OTDR’s expensive internal optical port from excessive wear and tear by shifting the mating cycles to the launch cable connectors.

• Custom Fiber Lengths: While 1km is standard, we provide rapid-turnaround production for lengths ranging from 100m to 2000m to match your specific pulse-width requirements.

• Variable Connector Mapping: We can customize any combination of LC, SC, ST, or FC connectors with APC or UPC polishing styles.

• Brand Integration: We offer full-color logo UV printing on the box exterior and customized serial number labeling for asset tracking.

• Custom Housing Colors: For large-scale fleet deployments, we can manufacture the outer casing in specific corporate colors (subject to MOQ).

• Technical Consultation: Our engineering team can assist in selecting the correct fiber type (G.652D, G.657A, or Multi-mode) to align with your regional infrastructure standards.

Global Logistics: We utilize specialized protective packaging to ensure the internal fiber remains stress-free during transit. Standard configurations are usually available for immediate dispatch, while custom connector assemblies typically ship within 5–7 working days.

Q1: Why is a 1km length recommended over shorter cables? A: A 1km length provides a wider safety margin. It allows the OTDR to use various pulse widths without the risk of the “Dead Zone” overlapping the first connector of your actual network.

Q2: Can I request different connector types on each end? A: Absolutely. We specialize in hybrid configurations (e.g., LC/APC to SC/UPC) to eliminate the need for extra adapters, which can introduce unwanted loss into your test setup.

Q3: Is the internal fiber replaceable if a connector is damaged? A: While the fiber is sealed for environmental protection, we offer a re-termination service or can provide replacement pigtails for experienced technicians to perform field repairs.

Q4: Does the box include a calibration certificate? A: Yes, every unit undergoes rigorous insertion loss (IL) and return loss (RL) testing. A detailed test report is included in the box to guarantee performance from day one.
