## Product families
- [Optical fiber: G.652.D, G.657 and multimode](https://connect.zerolineai.com/products/optical-fiber/): ZeroLine Connect supplies bare optical fiber from Optics Valley’s fiber makers to cable plants and assemblers: G.652.D single-mode, bend-insensitive G.657.A1, A2 and B3, and OM3, OM4 and OM5 multimode. Fiber ships on reels with the maker’s datasheet and test data for every reel, under spot orders or long-term supply agreements. Types: G.652.D; G.657.A1; G.657.A2; G.657.B3; OM3; OM4; OM5.
- [Outdoor optical cable: duct, aerial, ADSS and direct-buried](https://connect.zerolineai.com/products/outdoor-cable/): ZeroLine Connect supplies outdoor optical cable for every route: loose-tube duct cable, ADSS and figure-8 aerial cable, armoured direct-buried cable and air-blown micro-cable, typically from 2 to 288 fibers. Cables are built to IEC 60794 by Optics Valley cable makers, with OTDR data for every fiber on every drum. Types: Loose-tube duct cable; Central-tube cable; All-dielectric cable; ADSS; Figure-8 aerial; Direct-buried armoured; Air-blown micro-cable.
- [FTTH drop cable and indoor fiber cable](https://connect.zerolineai.com/products/drop-indoor-cable/): ZeroLine Connect supplies the cable for the last metres to the home and inside buildings: flat and round FTTH drop cable, self-supporting drops with a steel messenger, tight-buffered simplex and duplex cable, and indoor distribution and breakout cable, all with bend-insensitive G.657 fiber and LSZH, PVC or PE sheaths. Types: Indoor flat drop (butterfly); Self-supporting drop; Round drop; Tight-buffered simplex / duplex; Indoor distribution cable; Breakout cable.
- [ODN and FTTx components: splitters, closures, cabinets and boxes](https://connect.zerolineai.com/products/odn-fttx/): ZeroLine Connect supplies the passive optical distribution network for GPON and XGS-PON: PLC splitters from 1×2 to 1×64, fiber distribution hubs and ODF, dome and inline splice closures, fiber access terminals, wall outlets and field-installable connectors. Splitters ship with insertion-loss data for every port. Types: PLC splitters; Fiber distribution hubs (FDH); Optical distribution frames (ODF); Splice closures; Fiber access terminals (FAT); Termination boxes and wall outlets; Field-installable connectors.
- [Fiber patch cords and pigtails](https://connect.zerolineai.com/products/patch-cords-pigtails/): ZeroLine Connect supplies fiber patch cords and pigtails in any length: LC, SC, FC and ST connectors, simplex and duplex, UPC and APC polish, single-mode and OM3, OM4 and OM5 multimode, including armoured and uniboot cords. Every cord is tested for insertion and return loss, with end-face geometry checked by interferometer. Types: Connectors; Polish; Fiber; Construction; Pigtails; Jackets.
- [MPO trunks, harnesses and cassettes for data centers](https://connect.zerolineai.com/products/mpo-mtp/): ZeroLine Connect supplies pre-terminated MPO cabling for data centers: trunks of 8, 12, 16 or 24 fibers, MPO-to-LC harnesses, cassettes and high-density panels, in OS2 and OM3 to OM5 fiber. Every assembly is built to your polarity method, tested for insertion loss and labelled to your rack and port plan. MTP® connectors from US Conec are available on request. Types: Trunks; Harnesses (fan-outs); Cassettes; Panels; Conversion modules; Accessories.
