company news about What are FTTH Drop Cable And Drop Patch Cord

In FTTH (Fiber-to-the-Home) networks, drop cables and drop patch cords are essential components used to connect the service provider’s distribution point to the customer’s premises.

1. FTTH Drop Cable (Drop Wire)

Definition:

A fiber optic cable used for the final connection from the optical distribution point (e.g., pole, splice closure, or terminal box) to the customer’s ONT/Modem.

Types:

Aerial Drop Cable: Designed for overhead installation (often includes a steel messenger wire for support).

Underground Drop Cable: Armored for direct burial or duct use.

Indoor/Outdoor Drop Cable: UV-resistant and waterproof for outdoor use but flexible enough for indoor routing.

Structure:

Single fiber or 2-fiber (most common in FTTH).

Tight buffer or loose tube design.

Bend-insensitive fiber (G.657.A/B) for tight bends.

Armored versions (rodent-proof, crush-resistant).

Connectors:

Often pre-terminated with SC/APC or LC/APC connectors (but may also be spliced on-site).

2. FTTH Drop Patch Cord (Fiber Patch Cable)

Definition:

A pre-terminated fiber optic jumper used to connect devices (e.g., ONT, router, distribution box) within an FTTH setup.

Types:

Indoor Patch Cord: Tight-buffered, flexible (for indoor use).

Outdoor Patch Cord: Waterproof, UV-resistant (for outdoor links).

Armored Patch Cord: Extra protection against damage.

Connectors:

SC/APC (most common in FTTH for low reflectance).

SC/UPC, LC/UPC, LC/APC (depending on equipment).
