AN OFS WHITE PAPER: NEW TECHNOLOGIES ENABLE FASTER, EASIER FIBER INSTALLATION INTO HOMES AND MDUs

Driven by unprecedented demand for Gigabit and fast emerging 10 Gigabit Broadband, Fiber to the Home (FTTH) deployment is expected to reach record numbers in the coming years. According to iDate, FTTH connections will more than double in Europe over the next six years, while RVA forecasts that FTTH investment in North America will double in the next five years compared to the previous five. In addition to homes, service providers are bringing fiber to the living unit in multiple dwelling units (MDUs) and into commercial and institutional buildings.
In all these scenarios, a cost-effective and compact optical network terminal (ONT) is typically placed inside each living unit or office to enable Gigabit or even 10 Gigabit connectivity. However, there are aesthetic and cost challenges to placing fiber inside residences or buildings. While service providers typically prefer to deploy ONTs
deep within subscribers’ units with co-located Wi-Fi:
- there may be no existing fiber ducts or pathways to the ONT location.
- installing new ducts or cutting and patching walls can be very expensive and disruptive.
- surface mounting conventional fiber cables can be unsightly and result in optical signal loss when the cables are bent around the many sharp corners on the pathway to the ONT.
- wire molding or tape systems to house fiber are typically cost prohibitive, visible. and very slow to install.
Good day, my name is John George. I’m Senior Director of Solutions and Professional Services with OFS. Today I want to share what’s new in my world that could help you build better fiber to the home (FTTH).
Originally, FTTH deployments were fiber to outdoor ONTs on the side of a house. From there, copper typically was used to reach an indoor residential gateway inside the home. Over time we discovered indoor ONTs are smaller, and less expensive. They could be deployed inside the home, co-located with the wi-fi in the center of the building and achieve much better wi-fi coverage. This would reduce the cost, but there had to be a way to get the fiber into the home to that indoor ONT.
For MDU’s and apartment buildings, it evolved from fiber to the building, and trying to use the existing in-building copper to bring the internet service to each living unit. That proved to be insufficient from a bandwidth perspective for MDUs. To support 10 gigabit data rates that are being deployed now, it’s desired by service providers to get fiber into each living unit of an apartment building.
I’ll walk you through some innovative technologies we offer, that help solve those significant problems. The first one is EZ-Bend Cabling Solution. This is a three-millimeter diameter cable. It can have connectors on both ends. It can simply be stapled around any corner, and bends sharply in half with no concern about loss whatsoever. It has a 2.5 millimeter minimum bend radius – that’s twice as tight as anything else you can get on the market. The best from others is only five millimeters.
The EZ-Bend 2.5 millimeter bend radius technology is even more necessary as we move to from gigabit, to 10 gigabit. 10 gigabit use longer wavelengths in the transmission system. Longer wavelengths have much higher bend loss than what’s used for the gigabit. So, cable bends in a 10 gigabit transmission is a bigger challenge, but we solve it with the EZ-Bend. You can literally bend it any way without concern for signal loss.
The next technology we offer is the OFS InvisiLight Solution. It‘s used to solve issues inside the home or apartment. Originally, stapling cables inside the home was acceptable. Now, many customers don’t want to see the fiber at all inside the living unit. The OFS InvisiLight Solution is fiber installed inside an apartment, or home that blends into its environment; nearly invisible to anyone looking directly at it. The OFS InvisiLight Solution gets the fiber deep inside to the ONT. We have connectors on both ends of the InvisiLight spool making it easier to deploy a single part number, that can cover up to 132 feet, getting fiber into a home or an MDU living unit.
We also have a 12 fiber version, and a 16 fiber version for MDU hallways. These editions to go down the hallway and drop off the single fiber InvisiLight into the living unit.
Finally, we have the EZ-Bend Single Family Drop Solution that includes drop cabling, from the pole or pedestal to the home, and into the home. This is a double end connectorized assembly that’s toneable orange and can be laid out as a temporary drop, then buried later. What’s beautiful about this is it has the InvisiLight fiber inside the cable, so you can run this to the house below grade, direct buried, or induct, then wrap the house with it, and then to extend into the home to reach the ONT. All that is needed is to strip the jacketing off and then what you have is the fiber outside going through the wall to the inside where we’ve got the InvisiLight deployed to the ONT. Essentially this is a single piece of glass all the way from the curb, into the home, and into connecting the ONT. Quite simple, one part number, you don’t need a Network Interface Device (NID). You don’t need the time to install the NID. You save dollars if you avoid conduit and the NID by going with the EZ-Bend Single Family Drop Solution to the home into the home straight to the ONT.
That’s what’s new in my world. Thank you for listening.
