Description
Built for the Field. Engineered to Survive It.
The SPROLINK LK4-FB is an 8-strand, single-mode armored tactical fiber cable on a rugged transport reel. Built from a spiral stainless-steel armor tube over a TPU outer jacket, it takes the abuse that standard patch panels can't — being dragged across parking lots, coiled on outdoor stages, buried temporarily, or run through rodent-prone ducts. You get stable, low-loss 10/40/100G connectivity where ordinary fiber cables would fail.
Why crews choose the LK4-FB
- Dual-layer mechanical protection — spiral stainless-steel tube + aramid strength members resist crushing, kinking, and rodent bites. Crush rating up to 5,000 N/10 cm (short-term).
- True outdoor jacket — flexible, wear-resistant TPU resists water, UV, oil and abrasion; LSZH/low-smoke construction for safety in tents, trucks and venues.
- Low-loss single-mode G.657A1 — ≤0.4 dB/km @1310 nm, ≤0.3 dB/km @1550 nm, with bend-insensitive fiber for tight cable routing.
- Precision ceramic LC/UPC ferrules — low reflection and insertion loss for clean links on cameras, switches, converters and SFP/SFP+ modules.
- Weather-sealed connector caps — each LC end ships with a dust/waterproof cap to keep interfaces clean between deployments.
- Ready-to-use on a reel — integrated carry reel with handle for fast deployment, clean re-winding and trouble-free transport between gigs.
Best for outside broadcast / OB trucks, live events & festivals, film & TV sets, temporary fiber backhaul, campus/industrial temp links, and rental/staging houses.
Operating temperature: -40 °C to +85 °C. Tension: 200 N long-term / 400 N short-term.
Length is configurable — select your required length from the dropdown, or contact us for custom connector types (SC/FC/ST, APC, MPO) and multi-mode OM3 variants.
