R&M USA debuts SYNO modular closure for FTTx networks

R&M, through R&M USA, has introduced the SYNO dome closure to the North American market. The outdoor closure is available in three models – for 288, 576, and 1,152 fibers, respectively, -- and will accommodate single or rollable fiber cables.

The SYNO dome closure features a modular system for cable entries that eliminates the need to thread fiber-optic cables through the closure base. It also does not require technicians to seal the enclosure using shrink tubes. The SYNO dome instead seals via integrated blocks made from R&M’s SYNO gel. Gel surrounds each cable to protect against dust and moisture. And the seals hold despite fluctuating temperatures, mechanical loads, or water pressure, says R&M. The integrated gel blocks are designed to be easy to open and replace or to reseal, the company adds.

The SYNO cable entries are positioned laterally in eight radially arranged bays in the closure duct. The cable entry kits are interchangeable and will support any desired configurations as well as mixed assemblies of cables and micro ducts, according to the company. The cable entries enable network operators to make tailored roll-out plans on short notice and integrate new fiber capacity or routings at any time, without having to replace the closure or to open existing splices, R&M states.

The SYNO dome closure features R&M’s Single Circuit Management System with scalable trays and efficient fiber management. R&M offers eight cable entry kits for configurations from one via two, four and eight up to 16 cables, optimized for typical cable diameters covering a range from 1 mm (0.04-inch) to 28 mm (1.1-inch) in cable diameter and micro ducts up to 14 mm (0.55-inch). The kits are configured to require no more than a 40-mm bend radius.

R&M foresees the modular dome closure as useful in a variety of applications, including distribution, branch, or cable joint closure. “The SYNO dome closure meets the requirements of network operators who prefer to deploy and modify infrastructure flexibly with as few limits as possible. The flexibility of this modular outside plant solution is unique; it supports typical application needs, mixed topologies, and cable types of modern fiber-optic networks. The SYNO product features are based on R&M’s many years of experience working with global FTTx customers,” said Aslam Zuberi, R&M’s FTTx market manager, North America.
