FiberStrike LCM-2700 Series Rugged Portable FBG Interrogator (LCM-2708)
A battery-powered, ruggedised eight-channel Fiber Bragg Grating interrogator for field monitoring of temperature, pressure and strain sensors. Supplied in a waterproof carrying case for outdoor and remote deployment.
Technical overview
The LCM-2708 reads up to eight FBG sensors on each of eight optical channels over a 70 nm C-band window, sampling at up to 19.2 kHz with 1 pm wavelength resolution. Data is logged to local USB storage or streamed over Ethernet or Wi-Fi and presented through the FiberStrike GUI. A configurable sleep/wake duty cycle extends battery endurance for periodic unattended measurement. The unit carries an IP67 rating and uses a waterproof MPO-style optical connector with a supplied fan-out cable.
