Optical Cables for Distributed Base Stations
17Pages

With the construction of 4G networks and'Broadband China', communication cables and equipments keep extending toward the subscribers. The power supply for equipments of remote base stations, communication rooms, access points for subscribers has become a tough problem. The solution of DC remote power supply by hybrid optical and electrical cables can not only facilitate the centralized construction and maintenance of power supply devices in the network, but also realize the efficient cable transmission of electric energy and optical signals. In addition to solving the aforesaid problems,...

Applications 1. Point-to-point • Scenario: network with single RRU or multiple RRUs • Applicable to the situation where RT devices are gathered at one point but far away from COT.

Single-mode/multimode fires are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. In the center of cable is a metallic strength member. The tubes and copper wires are stranded around the central strength member to form a cable core. The core is filled with cable filling compound and armored with corrugated steel tape. Stranded steel wires are applied as the messenger. Finally, a figure-8 PE outer sheath is extruded. Features • Accurate process control ensuring good mechanical and temperature performances • Optical and electrical hybrid...

Hybrid Optical and Electrical Stranded Loose Tube Cable (GDTA) Single-mode/multimode fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. In the center of cable is a metallic strength member. The tubes and copper wires (of required specifications) are stranded around the central strength member to form a cable core. The core is filled with cable filling compound and armored with laminated aluminum tape. Then, a PE sheath is extruded. Features • Accurate process control ensuring good mechanical and temperature performances • Optical...

Tight buffered fibres are surrounded with a layer of aramid yarns as the strength member. A LSZH inner sheath is extruded on the tight buffered fibre to form an optical sub-unit. Then optical sub-units and copper wires are stranded around a non-metallic central strength member to form a cable core. The core is armored with laminated aluminum tape. Finally, a LSZH outer sheath is extruded. Other sheath materials are available on request. Features • Good mechanical and temperature performances • Excellent crush resistance and flexibility • All-dry hybrid structure, supporting bulk data...

Note: Xn refers to fibre type, and G.657.A2 fibre is recommended. D is cable diameter. Copper wires with different cross sectional areas are available on request. Yangtze Optical Fibre and Cable Joint Stock Limited Company 067

Tight buffered fibres are surrounded with a layer of aramid yarns as the strength member. A LSZH inner sheath is extruded on the tight buffered fibre to form an optical sub-unit. Then optical sub-units and fillers are stranded into a cable core. Finally, a LSZH sheath is extruded outside the core. The fillers can be made of other high-strength yarns and other sheath materials are available on request. Features • Good mechanical and temperature performances • Excellent crush resistance and flexibility • Small size and light weight, supporting bulk data transmission • Mainly applied to...
