Technologies and Products

CommScope has announced the general availability of its modular Fibre Optic Splice Closure (FOSC) solution. The modular dome splice closure offers a new, modular seal design that leverages NOVUX technology to accommodate a range of applications in fibre-deep installations and deployments. The company has also announced CEx, a Coexistence portfolio which enables operators to add next generation PON services over their existing fibre infrastructure.

FOSC Modular Splice Closure

The FOSC Modular Splice Closure is designed to speed fibre installation and facilitate the servicing and extensibility of connections as operators build their networks. It is an all-in-one closure design with a modular architecture made to simplify the planning and logistics of network expansion. Featuring a wrap-around mechanical seal and interchangeable base segments, the dome splice closure works with a wide range of cable types available and canalso replace multiple closures.

With a modular base composed of eight interchangeable cold-seal segments, the dome splice closure delivers easy access to individual fibres. The closure allows cables to enter the chassis at several points, with no need to take apart and re-install the entire closure. The FOSC Modular Splice Closure enables operators to select a single closure to cover a range of network technologies, topologies, cable types, and installation requirements for their feeder and distribution. General availability is scheduled for November 2021.

“Our FOSC Modular Splice Closure is a breakthrough in versatility for fibre closures that will help accelerate the deployment of tomorrow’s high-speed broadband networks,” said James DeCoe, vice president, Network Connectivity, CommScope. “With its general availability, operators will be able to simplify their cable installations and have the peace of mind that their connections will continue to be protected as they evolve their networks.”


PON Coexistence portfolio

The CEx elements are part of CommScope’s portfolio of passive optical devices and are designed for seamless integration into CommScope’s inside and outside plant fibre connectivity solutions. These modules integrate into the network near the optical line terminals (OLTs), enabling existing PON services to coexist with XGS-PON, NG-PON2, RF video, and optical time domain reflectometer (OTDR), as well as other current and future technologies. With the future in mind, an included GPON port passband allows for upgrades to 25/50G services.

CEx elements are available in four configurations (CEx 1, CEx 2, CEx 3, and CEx4), two housing styles (NG4 and LGX), and two connector types (LC/APC and SC/APC)—offering multiple configurations to suit a range of applications. The CEx portfolio is complemented by CommScope’s dedicated fibre expertise in field deployments and network service—including the design, planning, and implementation of passive optical devices.

“Our new CEx portfolio is a revolutionary solution for our GPON customers to looking achieve higher data rates and deliver new enterprise, mobile backhaul, and residential services without adding additional fibre,” said James DeCoe, vice president, Network Connectivity, CommScope. “Our coexistence elements offer a clear path to upgrading to future PON services without changing the outside plant infrastructure, and we offer the corresponding expertise to simplify network-wide planning and deployment.”
