Red Laser Fibre Test Pen

Physical dimensions: 19.5 cm length × 7 cm width × 3 cm depth. Build: hybrid construction using aluminium alloy for structural rigidity and thermal stability, plus engineered plastic for weight reduction and grip texture. Laser specification: fixed-wavelength red light source with stable 5 mW output power. Features dual operating modes—continuous wave (CW) for linear tracing and glint (pulsed) for enhanced fault contrast under variable lighting. Designed specifically to reveal physical-layer anomalies such as fractured cores, kinked cable sections, crushed jackets and poorly seated connectors via visible red light leakage. Compatible with standard FC, SC, LC and ST connector types when used with appropriate adaptors (not included). Deployed across fibre-to-the-home (FTTH), mobile backhaul, university campus networks and broadcast infrastructure. Comes complete with compact strap for waist or pocket carry and concise printed manual outlining safety guidelines, battery replacement (if applicable—omitted per source), and interpretation of observed light patterns.
