EXFO LFD-202E Live Fiber Detector with Core Power Display

The EXFO LFD-202E Live Fiber Detector quickly measures signal presence or absence on single mode fibers. It can analyze various customer traffic signal types for both continuous and modulated signals at 270 Hz, 1kHz, or 2kHz. The tester checks for signal type and direction before rerouting or maintenance and doesn't disrupt traffic or over stress the fiber. It has a core power reading display and features a max power range of 23 to -50 dBm, over-range indicator and spectral response from 800 nm to 1700 nm.

The LFD-202E contains the main unit, 3mm, 900, and 250/RIB interchangeable fiber heads.

KEY FEATURES

• No need to open fi ber for identifi cation
  
• Hands-free operation via Hold button
  
• Three interchangeable adapter heads
  
• Extended range model: 23 to –50 dBm

NO-DISCONNECTION LIVE FIBER DETECTION

The LFD-200 Live Fiber Detector allows you to detect traffic and measure signals anywhere on singlemode fibers without having to disconnect them. It also lets you check for signal presence before rerouting or maintenance, perform continuity tests and verify cable labeling.

Based on non-destructive macrobending technology, the LFD-200 doesn’t disrupt traffic, damage or overstress the fiber, enabling efficient, accurate and reliable data acquisition.

Simple Testing of Multiple Fiber Types 

EXFO’s LFD-200 is the only instrument of its kind on the market that comes with a choice of three built-in, interchangeable adapter heads, making it an all-in-one solution for live fiber detection. The handle’s storage compartment holds the extra adapter heads for simple conversion and easy testing of various fiber types.

The LFD-200 also features a unique Hold button that enables hands-free operation. Just push up the button and click it down. You are now free to operate your setup.

COMPLETE DIAGNOSIS. FAST.

Simply clamp the LFD-200 onto a fiber, listen for a beep indicating the presence of traffic, then view a complete status report on the multifunction LED display:
› Signal presence or absence (live or dark fi ber)
› Signal type (customer traffi c, continuous or modulated test signal at 270 Hz, 1 kHz or 2 kHz)
› Signal direction
› Core power within 2 dB (typical)
