LONGTOL Fiber is a Shanghai-based trading house for the global connectivity supply chain. We move 5,000,000 km of optical fibre a month — alongside mission-grade UAV avionics — from China's leading cable and avionics cluster to your port, your warehouse, your project.
Six ITU-T / IEC families. Standard reels 1 / 2 / 4 / 25 / 50 km. Custom attenuation, cut-off wavelength, mode-field diameter on request.
Standard single-mode fibre for access and FTTH networks. Conventional water-peak attenuation, full ITU-T compliance, cost-optimised for high-volume deployments.
Standard single-mode fibre for long-haul, metro and access networks. Low water-peak, full spectrum compatibility, mature global supply.
Bend-insensitive single-mode for in-building, FTTH drop and indoor cabling. Low macrobend loss at 15 mm radius.
Ultra-bend-insensitive single-mode. A2 for FTTH drop with 7.5 mm bend; B3 for indoor micro-cable with 5 mm bend radius.
Cut-off shifted single-mode for ultra-long-haul and submarine cables. Larger effective area, low non-linearity, 400G+ coherent ready.
Non-zero dispersion shifted fibre for high-bit-rate DWDM long-haul. Reduces XPM / FWM in dense wavelength systems.
Wideband non-zero dispersion fibre for combined CWDM / DWDM systems across S + C + L bands (1460 – 1625 nm). Note: G.709 refers to the OTN digital-wrapper protocol and is not an optical-fibre grade — we supply transponder-grade optics on request.
Laser-optimised 50 µm multimode for 10 / 40 / 100 GbE data-centre and enterprise backbone. OM4 extends 100 Gb/s to 150 m.
Wideband multimode for Shortwave Wavelength Division Multiplexing (SWDM) across 850 – 953 nm. Optimised for 100 / 400 GbE.
Legacy multimode for 1 GbE and short-reach enterprise. OM1 (62.5/125) and OM2 (50/125) for retrofit and short patch applications.
Polarisation-maintaining fibre for fibre-optic gyroscopes, LiDAR, coherent sensing. Panda, Bow-tie and elliptical-clad constructions.
Erbium-doped fibre for C-band and L-band EDFAs. Tunable absorption, splice-compatible with G.652. Core diameters 4 – 8 µm.
Dispersion-compensating fibre for high-bit-rate long-haul. Large negative dispersion compensates accumulated G.652 chromatic dispersion.
Double-clad and large-pitch fibres for high-power fibre laser delivery. Cladding-pumped, kW-class CW and pulsed laser systems.
FTTH indoor drop cable with G.657A1/A2 fibre, self-supporting bow-type or flat. Steel wire messenger optional.
Stranded loose-tube outdoor cable with G.652D fibre. Single-mode up to 144 cores. Duct, aerial and direct-buried constructions.
Single-mode / multi-mode patch cord with simplex or duplex connectors. UPC / APC polish. Custom lengths.
Private-label fibre drums. Non-standard attenuation, cut-off, MFD or coating per your spec. Custom printing, barcodes, drum markings.
From residential last-mile to transoceanic cables, our G.652 / G.654 / G.655 / G.657 fibre series delivers unmatched performance across every deployment scenario.
Fiber-to-the-Home and Fiber-to-the-x deployments demand fibres that can navigate tight bends in residential buildings without signal degradation. G.657 series provides the bend performance needed for last-mile connectivity.
High-density patching environments with thousands of connections in confined spaces require ultra-low bend-loss fibres to maintain signal integrity in tight cable management systems.
5G base station fibre backhaul requires compact, rugged fibre cables that can withstand tight bends in outdoor enclosures and pole-mounted installations across varying climates.
Undersea and harsh-environment deployments demand fibres with exceptional mechanical durability, low attenuation over extreme distances, and resistance to hydrogen aging.
Factory automation and industrial IoT networks require ruggedized fibre solutions that maintain performance under vibration, temperature extremes, and electromagnetic interference.
Urban fibre grids for CCTV, smart lighting, and IoT sensor networks need compact, easy-to-install cables with superior bend tolerance for congested underground ducts.
