As a product engineering service provider, we've witnessed firsthand the rapid evolution of communication technologies. Today, we stand at the precipice of a new era in in-home networking: Fiber to the Room (FTTR). While the promise of seamless connectivity and enhanced performance is tantalizing, the path to widespread adoption is fraught with challenges. In this post, I'll illuminate some of these hurdles, drawing from the latest research and industry insights, and explain how our services can guide you to success in the FTTR market.
The Challenge of Clarity:
One of the primary obstacles in the FTTR market is a lack of clear definitions and consistent terminology. The sources reveal a number of terms that can lead to confusion:
- Network Levels: The distinction between NE4 (building network) and NE5 (in-apartment network) is often blurred, even in official documents. For clarity, the term "Faser-NE5" refers to a fiber-based NE5.
- FTTR Variants: The term FTTR is used as an umbrella term for various implementations including G.fin, G.p2pf, and HomePON, but sometimes it's misused to refer to specific variants, leading to misunderstandings. Further complicating things is the use of terms like FTTR-H (for homes) and FTTR-B (for businesses).
- Equipment: Even the terms for Optical Network Units (ONUs) are evolving, with Main ONUs now called Main Fiber Units (MFU) and Sub ONUs now called Sub Fiber Units (SFU). It's important to note that SFU should not be confused with Single Family Unit.
- Marketing: Marketing materials often use the phrase "WiFi in every corner" to promote FTTR, further obscuring the specific technology being used.
These "Unschärfen" or lack of clarity in terminology are not mere semantic quibbles. They can lead to miscommunication, hinder interoperability, and ultimately slow down market adoption.
The Challenge of Diversity:
The FTTR landscape is not monolithic. The sources highlight several distinct approaches to FTTR, each with its own strengths and weaknesses:
- G.fin: This FTTR variant, based on a Point-to-Multipoint (P2MP) architecture, is prevalent in China and leverages existing GPON/XGSPON components. SFUs in this variant come with wired and wireless interfaces, and it commonly uses a hybrid fiber/power cable. It is widely used in new buildings.
- G.p2pf: This Point-to-Point (P2P) variant, championed by Nokia, doesn’t require splitters, and it can use one or two fibers. A single-fiber option uses two wavelengths.
- HomePON: An earlier approach, now trademarked by Huawei, which is also referred to as RoomPON by ZTE.
- G.hn based: This version uses a reflective coupler and is considered the basis for a migration strategy from copper to fiber.
Understanding these differences is crucial for product development and deployment. The sources show that market figures are often inaccurate, because the specific FTTR variant in use is not mentioned.
The Challenge of Migration:
For many, the transition to FTTR will not be a greenfield deployment. The sources emphasize the need for seamless migration strategies, particularly in existing buildings where copper infrastructure is already in place. It is possible to reuse copper cabling (in walls or conduits) for wired backbones for wireless APs. A passive infrastructure following the standard DIN EN 50173-4 is a good basis for any FTTR variant. In this regard, the G.hn based approach to FTTR is well suited to a phased migration because it also allows the use of single-fiber solutions that use only one wavelength.
