fiber internet installation

First, let's start with fiber-optic internet. Fiber-Optic or Fiber Internet uses cutting-edge technology to transmit data through ultra-thin glass cables.

Fiber offers a stable, wired connection that is faster and more reliable than traditional broadband.

See our table below to compare the pros and cons of Fiber Internet, and what Sakura Mobile has to offer

Pros👍

Cons👎

Ultra-fast speeds: 1 Gbps or up to 10 Gbps (with Sakura Mobile).Installation required: It can take from 1 week to 1 month to set up.**
Low latency: Perfect for gaming, streaming, and remote work.*Fixed location: Not as portable as home WiFi.
Unlimited data: Ideal for heavy internet users.May not be feasible: Shared housing or certain apartments may not support fiber installations.



*Latency is the time it takes for data to pass from one point on a network to another.

**Sakura Mobile provides support for negotiations in Japanese (ex. confirming installation details with your property manager).
