MiDia® & MiDia 200 Outside Plant Cable

The reduced diameter MiDia and MiDia 200 Outside Plant (OSP) Cables are an ideal cabling solution for heavily congested duct spaces in metropolitan fiber optic networks. With one of the smallest loose tube cable diameters capable of supporting up to 864 fibers, these lightweight, yet durable cables help save service providers time and money with fast, air-blown deployment into new or existing ducts.

The construction of the MiDia and MiDia 200 OSP Cables begin with Lightera’ field-proven loose tube designs. Up to 12 (250 micron)or 24 (200 micron) optical fibers are placed into each water-blocked buffer tube to protect the fibers from environmental and mechanical forces. Both the optical fibers and buffer tubes are color coded for easy identification. The buffer tubes are then stranded around a dielectric central member using the reverse oscillating lay (ROL) stranding technique. Next, dry water-blocking material is applied to the cable core for exceptional water penetration resistance and faster cable preparation. For extra mechanical protection, a layer of non-metallic strength elements is then added. To complete the construction, two ripcords are placed beneath a durable, outer polyethylene (PE) jacket for easy cable preparation and sheath removal.

With the MiDia 200 OSP cable, service providers can achieve up to a 100 percent increase in fiber density in a single, reduced diameter cable. This gain in density allows providers to maximize the use of their network duct systems and infrastructure. For example, a deployment using two MiDia 432 fiber cables could now be replaced by a single 864 fiber MiDia 200 cable installed into a 32/26 mm (OD/ID) duct. This capability makes it easier to increase fiber counts, even in highly congested duct systems while helping to save on material and installation costs and retaining space for future upgrades or lease.
