R&M USA, a specialist in cabling systems for high-quality network infrastructures, has this month launched its SYNO dome outdoor closure platform for North American fiber-optic networks.
The SYNO dome closure is the latest addition to R&M USA's line of FTTx portfolio products, all designed to integrate end-to-end FTTx connectivity from the central office to the end-user premises site. The SYNO dome closure is available in three models – 288F, 576F and 1,152F accommodating single or rollable fiber cables.
The dome closure features a modular system for cable entries that the manufacturer says eliminates the laborious task of threading fiber-optic cables through the closure base. The system also eliminates time-consuming sealing using shrink tubes. Instead, integrated blocks made from R&M's SYNO gel technology seal the splice closure.
According to Aslam Zuberi, R&M's FTTx market manager, North America, "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."
Per a company statement:
The innovative and highly modular SYNO gel technology used by R&M is setting a new standard in mechanical cold sealing of closures. When the cable entry is sealed, gel surrounds each cable, preventing dust and moisture from entering. Fluctuating temperatures, mechanical loads or water pressure cannot damage the dome closure in any way. The gel blocks integrated into the cable entry kits are also easy to open and replace, are resealable and offer long-term stability.
The SYNO dome closure modular cable entries revolutionize the assembly process in FTTx outside plant applications and simplify maintenance work during operation. The cable entries allow network operators to make tailored roll-out plans at short notice, and integrate new fiber capacity or routings at any time, without having to replace the closure or to open existing splices.
Technical notes
In the platform's layout, the SYNO cable entries are positioned laterally in eight radially arranged bays in the closure duct.
The system's cable entry kits are interchangeable and support any desired configurations, as well as mixed assemblies of cables and micro ducts.
The cable entries can be opened, closed, changed, and retrofitted in a few simple steps. The cable bays and individual cables remain freely accessible, so that the dome closure can be modified or fitted with additional fiber-optic cables during network operation.
Inside the SYNO dome closure is R&M's Single Circuit Management System, with scalable trays and ultra-efficient proprietary fiber management technology. R&M offers eight different 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") to 28 mm (1.1") in cable diameter and micro ducts up to 14 mm (0.55").
The company contends the platform's modular dome closure concept "suits virtually any application, such as a distribution, branch, or cable joint closure. A bending radius of 40 mm is gentle on fibers and is guaranteed regardless of packing density," concludes the product announcement.
