10KM Fiber Optic Launch Cable Box | OTDR Test Fiber G657A2 FC/UPC

Description

10km Fiber Optic Launch Cable – Reliable OTDR Test Box G657A2 FC/UPC

Overview

This 10 km single-mode fiber optic box is built for fiber network testing and installation work. It uses G657A2 bend-insensitive fiber, and the compact 13×31 cm spool lets you carry long fiber lengths easily. Each unit is QC-tested before dispatch. It suits ISPs, telecom technicians, FTTH installers and network engineers.

Key Specifications

10KM Fiber Optic Launch Cable Box (OTDR Test Fiber) – G657A2, FC/UPC

Description

G657A2 fiber stays low-loss even when bent to tight radii, so it is more forgiving to handle than standard G652D fiber. Attenuation is low at both common wavelengths (≤0.35 dB/km at 1310 nm and ≤0.25 dB/km at 1550 nm), which keeps signal loss small over the full 10 km. The FC/UPC connector has a threaded coupling that holds securely, and its ultra-physical-contact polish gives low insertion loss and good return loss. FC connectors are widely used on OTDRs and test equipment.

Common Uses

• OTDR testing: works as a launch cable to push the instrument’s dead zone out of the way, so the first connector and the start of the link can be measured accurately.
• Fiber loss testing and troubleshooting: gives you a known reference length for checking equipment.
• Training and demos: useful for technical institutes and workshops that need a long fiber without laying cable.
• Lab and field simulation: simulates long-distance links for testing transceivers and network gear.
• FTTH and telecom maintenance: handy for ISPs and contractors working on fiber-to-the-home networks.

• Why Choose G657A2 Fiber?

  G657A2 fiber is designed to keep signal loss low even when it is bent to tight radii. Standard fiber can lose signal or break when coiled tightly, but G657A2 handles tight coils and sharp turns much better. That makes it a practical choice for technicians who carry and reuse their test fiber every day, and for indoor setups where space is limited.

  Frequently Asked Questions

  What length is this fiber box?
  It contains 10 km of single-mode fiber, wound on a compact spool.

  What connector does it use?
  It has an FC/UPC connector, which is common on OTDRs and test instruments.

  Is it suitable for both 1310 nm and 1550 nm testing?
  Yes. Attenuation is rated at ≤0.35 dB/km for 1310 nm and ≤0.25 dB/km for 1550 nm.

  Can I use it with my OTDR?
  Yes, if your OTDR has an FC port or you use a suitable adapter.
