POsite Optical & Power Composite Cables
ZTT POsite (Optical and Power composited) cables integrate fibre and DC power in a single armored cable, replacing separate optical and power runs on the tower. The family covers outdoor BTS cabling for 3 RRU (7/8″ corrugated aluminium armor, same OD as RF feeder — traditional accessories reusable), 1 RRU tower-top jumper (1/2″ OD, 1 power pair + 2 fibre pairs), indoor Active IBS between BBU/AU, RHUB/EU and pRRU/RU units, FTTH access with butterfly / figure-8 conductor for excellent stripping performance (flame retardant to IEC 60332-1, CPR certificate available), and factory-assembled jumper solutions including hybrid enclosures and IP67 sealing kits. Solution has been supplied to Telkom Indonesia, Taiwan Mobile 5G, Huawei / ZTE Active IBS (64,118 km delivered), Nokia Siemens, Rogers Canada and the Australian market.
Features & Characteristics
- ▪All power & optical cables in one outer corrugated aluminium armor.
- ▪Outer diameter matches traditional 7/8″ or 1/2″ RF feeder — existing accessories can be reused.
- ▪Photoelectric transmission eliminates secondary wiring and reduces engineering costs.
- ▪Butterfly / figure-8 FTTH structure with excellent stripping performance.
- ▪Flame retardant per IEC 60332-1; CPR certificate available.
- ▪UV-, fire-, rodent- and bird-resistant sheath variants available (bird-proof sheath option).
- ▪Assembly jumpers factory-terminated with IP67 sealing kits and hybrid enclosures.
Applications
- ▪Outdoor 4G / 5G macro base stations (tower and rooftop).
- ▪Indoor Active IBS between BBU/AU, RHUB/EU and pRRU/RU units.
- ▪FTTH access networks — IPTV, internet, multimedia telephony, voice.
- ▪Long-distance BTS backhaul, MDF-to-ODF cabling.
