Broadband SoHo Verizon FTTP Tutorial

Verizon is currently maintaining an aggressive deployment schedule of their FTTP (PON) services. This new service architecture is a fiber (optical) platform, allowing today’s independent services (Voice, Data, TV) to be placed on a single fiber to the customers residence. This new architecture build out will resolve many issues for Verizon with its current aging copper plant and limited broadband capacity. With the deployment of this service Verizon will have the overall ability to offer its customers a true single bill for all the above services along with supplemental services with real time capabilities.

                    

DISCLAIMER : This page was created as a basic technical overview of Verizon's FTTP service for new field technicians interested in this technology, and to help you recognize some of the visible equipment that gives you a sign that service is being deployed in your area. Within this document I will make reference to some manufacturers and illustrate their products. Do NOT reproduce any of the below pictures or information out of its context listed below. Please don't email us with any questions out of context listed below as we can't discuss any other technical issues or speculation of vendor companies. All text listed below is solely the opinion of BroadbandSoHo, and based on the overall architecture of a PON, and integration into an existing telco architecture. This page will be updated when we have the chance to expand on further topics and company hyperlinks of service updates. 

This page is currently under construction ... as time permits it will be completed as soon as possible.

• OLT (Optical Line Terminal)

This unit resides in the local Verizon CO (Central Office) cross connected to the video and data networks that will be delivered to your home, it consists of a special DFB (Distributed Feedback) calibrated laser that is always on. The OLT control card acts as a traffic signal to the remote ONT's for complete data / video throughput upstream and downstream.

• ONT (Optical Network Terminal)

This is the CPE (Customer Premise Equipment) endpoint of the ODN. The ONT  is an Optical to Electrical to Optical device, that delivers your triple play services. It will replace your existing copper NID (Network Interface Device), and coax connections. The existing POTS / Coax inside wiring will be cross connected to the ONT. Since we understand that a PON is completely passive the endpoint must contain an AC voltage connection to perform the Optical to Electrical conversions for your services.

 

* SFU (Single Family Unit)

The SFU ONT is primarily used in single dwelling homes. This ONT will replace your existing demarc that currently delivers your home service. This same unit (The 611i is the preferred model for this deployment) can also be used in MDU Garden Style installations. In these MDU installations the SFU is preferred so that the ONT can be placed directly in the unit, with the responsibility and electric cost passed to the customer.

(From Left to Right)  Pic 1- Each property will have a main buried drop splice-point from the main FDH servicing the property. Pic 2 - Each individual building will have a buried fiber pig-tail spliced into the main fiber back to the FDH. Pic 3 - This fiber pig-tail is already pre-terminated to that new FDT, which will usually be located next to existing OSP facilities.

Verizon MDU - High-Rise Installation

The Tellabs MDU ONT will be used primarily in high-rise buildings. There are several models that can be deployed, each with specific transmission methods. Depending on the existing infrastructure facilities, an Ethernet or VDSL model will be installed. With the installation of an MDU ONT, you take advantage of the buildings existing cable facilities. This method is cost efficient compared to the cost of fiber deployment to each unit.

Corning ClearCurve™ Solutions for MDU Networks

The future deployment (currently in trial) solution for the Verizon MDU build-out will be this solution. The development of this new fiber-optic cable resolves the current build-out issues in the high-rise market.

MDU - Frequently Asked Questions

 

Which installation is better the 611i SFU or MDU ONT ?

In regards to an MDU, the 611i build-out is cheaper when it's a "garden style" meaning three-story or less building. This installation also takes fiber directly inside the apartment. In a high-rise building, this can become very costly to say the least. The only way the high-rise deployment using the 611i would be cost effective is if it's a new building construction. (Note: This is also the only time you may see the use of the Ethernet MDU ONT) Otherwise the use of an MDU ONT is the most cost effective form of deployment in a high rise.

In an MDU ONT installation , how will the service be delivered to my apartment ?

Your apartments existing copper and coax cable will be connected to the new MDU ONT demarc located outside your apartment. With the VDSL model your data will be delivered to your apartment across your same copper pair your home POTS service is on. If you have ADSL now it will be delivered that same way. You will be given a BHR (Broadband Home Router) that will have a VDSL modem built-in that will connect to your computer. Video service will be delivered across your existing coax cable, extended from the ONT's RF port.

Example of possible deployment method - VDSL ONT deployed respectively to keep maximum service within specs, may include multi-floor deployments. Install new video riser extending from ONT RF port to then connect to existing lateral taps.

With the MDU VDSL installation , how fast can my connection be ?

There are two VDSL transmission methods. The first generation VDSL-1 can deliver speeds up to 15-40 Mbps in real-life deployments, VDSL-2 can deliver speeds up to 80-100 Mbps. These following factors play a part, condition of the copper loop, and distance from the ONT. With the fact that I'm from NY and the existing copper plant in these buildings are on average older than 30 years, with all types of splices etc from over the years, that's a real-life scenario. With that in mind VDSL-2 will most likely be the deployment of choice due to it's better transmission scheme @ 30Mhz, and it will also be on the GPON network, for better bandwidth and other features. These specs are only relevant on loop lengths of 1000ft or less from the ONT.      Please refer to the DSL Forum for VDSL specs.

What factors can cause my building from not being deployed ?

There are several factors, the major one at the top of the list is property owner / co-op requirements. This can vary from issues (Equipment locations, who will pay for monthly ONT electric bill, etc) of how they may want the system deployed, a form of monetary compensation for access to the building or each unit serviced. Remaining factors being, if your building has an exclusive rights agreement with another company. Also if your existing cable company installed the coax cable and has rights to it, this will prevent Verizon from connecting to that same coax cable to deliver service to your apartment via the existing cable. This will change the deployment scheme and can become costly, if Verizon views your property not feasible (getting a high percentage of users), your building may not be deployed with video service at that time. Finally, sad to say but when a property has had a previous bad experience with a company, it's hard to gain there trust again.
