When installing fiber at an MDU (multi-dwelling unit), technicians have a few choices for the type of cable they choose. The most important choice is whether to use field-terminated or pre-terminated cable. Both have their strengths and weaknesses, but we find pre-terminated cable is almost always the best choice. In this blog, we’ll discuss the pros and cons for pre-terminated versus field-terminated cable when it comes to cost, installation skills and excess materials.

The ongoing data center and enterprise network challenge to rapidly migrate to 40 and 100G transmission speeds (with 200 and 400G on the horizon) coupled with ongoing changes in connectivity—such as parallel optics, PAM4, and OM5 wide band multimode fiber with short wavelength division multiplexing (SWDM)— requires less tolerance for errors and much tighter loss budgets. These ever-increasing transmission speeds in conjunction with more complex connectivity heighten the probability that connection reflectance could lead to network failure. Consequently, accurate and comprehensive testing and measurement is more crucial today than ever before.

The introduction of Gbps service is dramatically changing cable broadband. Many new innovations are finding their way into cable operators’ plants and many others are on the way. With DOCSIS® 3.1 deployments well underway and DOCSIS Full Duplex (FDX) on the horizon, operators have the promise of symmetric Gigabit services. At the same time, some operators are starting their migration to fiber deep networks while others are looking at Distributed Access Architectures (DAA) such as Remote PHY. All of this will have significant impact on the way operators manage their traffic engineering and network capacity planning.

During SCTE•ISBE Cable-Tec Expo® 2017, at the session, “Traffic Engineering Optimization II,” I’ll be discussing the ramifications of these issues and the significant impact they will have on the way operators manage their traffic engineering and network capacity planning.
