Televes VF-G657A1-150 singlemode OTDR startfiber 150m 236190

Singlemode OTDR launch fiber with a 150 m length, engineered to eliminate dead zones during fiber optic testing. The bend-insensitive G.657.A1 fiber ensures reliable measurements even when coiled tightly.

Advantages

Bend-insensitive fiber allows a minimum bend radius of 10 mm without significant loss, making it easy to handle in the field. Low attenuation values at both 1310 nm and 1550 nm provide accurate OTDR measurements by revealing the true characteristics of the link under test.

Suitable for

• OTDR dead zone elimination
• Fiber optic network testing and certification
• Field and laboratory use

Key specifications

• Fiber type: Singlemode, ITU-T G.657.A1 (bend-insensitive)
• Length: 150 m
• Core/cladding diameter: 9/125 µm
• Attenuation: ≤ 0.35 dB/km @ 1310 nm, ≤ 0.22 dB/km @ 1550 nm
• Minimum bend radius: 10 mm
• Connectors: none (bare fiber ends)
• Operating temperature: -20°C to +70°C

Recommendations

Ideal for technicians who need a compact, reliable launch fiber for OTDR testing in tight spaces, thanks to its bend-insensitive design.
