Sumitomo Electric Preconnectorized Cables: Save Time and Cost

May 31, 2023

As these networks process more and more data, they require an increase in transmission capacity as quickly as possible. One issue arising from this increase is that cables that connect DCs are usually installed in underground ducts with limited space and short installation timelines. This challenge has resulted in a demand for optical fiber cables with higher density which maximize duct space and minimize installation time and cost.

In response to these needs and challenges, Sumitomo Electric Lightwave (SEL) has developed a 3456-fiber pre-connectorized ultra-high-fiber-count (UHFC) optical fiber cable that uses 200 µm Freeform Ribbon® fibers and a slotted core structure. At both ends of the cable, 144 pcs of 24-fiber multi-fiber push-on (MPO) connectors (with an insertion loss of <0.35dB) are fully factory assembled at each end. Because these MPOs are factory assembled, no additional connector assembly is required in the field; simply plug them into the adapters.

For ease during installation, the preterminated cable comes in a protection tube made of a spiral metal tube with resin coating. This allows for the same level of the mechanical performance as the cable, such as tensile strength, compressive strength, and waterproofing while still protecting the series of sealed, factory-terminated MPOs.
