1KM single-mode OTDR cable extension box for launch cable and fiber optic cable

Welcome to our shop!

Discover our OTDR launch box, essential equipment for fiber optic testing, ensuring accurate and reliable measurements. Its robust polypropylene construction provides excellent sealing, making it waterproof, dirt-resistant, and explosion-proof. The seamless mid-fiber design makes it compact, lightweight (approximately 737g / 26oz), and easy to transport.

Made from non-metallic materials, it is resistant to sagging, corrosion, and electrical conductivity, ensuring a long service life. Its typical loss is less than 0.5 dB/km (at 1310 nm over 1000m), guaranteeing optimal working efficiency.

It is specifically designed to eliminate blind spots during OTDR testing. These blind spots, primarily caused by intense light reflection and pulse width, can extend over hundreds of meters.

By placing this launch box between the OTDR and the circuit under test, the blind spot is confined to the extension cord, thus minimizing any significant impact on the primary link under test. **Product Details:** **Condition:** 100% New **Item Type:** OTDR Launch Box **Material:** Polypropylene **Operating Temperature Range:** -40°C to +55°C **Typical Loss:** <0.5 dB (1000m to 1310nm) **Dimensions (L x W x H):** Approx. 23.4 x 13.2 x 6.4 cm / 9.2 x 5.2 x 2.5 inches **Weight:** Approx. 737g / 26 oz
