This article covers Telekom 光ファイバーモデム2 ブラック 最大2GBIt.
Overview
The Telekom Fiber Modem 2 Black (Gf-TA) is a dedicated fiber optic modem designed for Deutsche Telekom's fiber network in Germany. It supports up to 2 Gbps internet speeds and connects to your existing router or PC via a standard Ethernet (RJ-45) port. The package includes a fiber optic cable and socket for direct connection to the Gf-TA (fiber subscriber junction box). Setup is straightforward, requiring no manual configuration beyond plugging in cables. This modem is ideal for Telekom fiber subscribers who already have a router and want a simple, reliable modem-only solution.
Connectivity & Compatibility
This modem is exclusively compatible with Telekom's fiber optic network. It connects to the Gf-TA termination point via the included fiber cable. The single Ethernet output (likely Gigabit or 2.5 Gigabit) can be connected to any router, switch, or PC with a corresponding port. To achieve the full 2 Gbps speed, both the modem and the device it connects to must support 2.5 Gbps or faster Ethernet. It is not compatible with other ISPs (e.g., Vodafone, 1&1, or any non-Telekom fiber service). Additionally, the modem uses European power standards and is intended for use in Germany only; it will not work with Japanese fiber networks.
Product Info
Release date is unconfirmed but likely 2025 or later. On online retailers, it is priced at ¥12,210 (tax included). Warranty details are not publicly listed, but Telekom typically offers 2 years of coverage. Accessories include one fiber connection socket, a fiber optic cable, and a quick-start guide. Market positioning: entry to mid-range. As a first-party Telekom accessory, it guarantees compatibility and stable performance on Telekom networks, but it has no utility outside that ecosystem.
Best Use Cases
- Telekom fiber subscribers who want a standalone modem: If you prefer to use your own router (e.g., a high-end Asus or Ubiquiti), this modem lets you do that without the bloat of an all-in-one gateway. It passes the fiber signal to your router via Ethernet.
- Users replacing a faulty Telekom modem: If your existing integrated router/modem has a dead modem section, this standalone unit can serve as a direct replacement, preserving your current router.
- Power users on 2 Gbps plans: To take full advantage of Telekom's fastest consumer tier, this modem is required. Ensure your router has a 2.5 Gbps WAN port, or you will be limited to 1 Gbps.
Not suitable for: users on other ISPs, residents outside Germany, or those who prefer an all-in-one modem/router combo.
