⚡ What it is

FlySpark Fiber Optics Spool V2.0 is a rugged, field-ready fiber reel built for rock-solid, low-latency FPV + data links from 1 km up to 30 km—without the headache of RF noise, jamming, or interference that destroys wireless links.

✅ Why teams choose fiber (simple truth)

• Zero RF interference: fiber doesn’t care about crowded 2.4/5.8 GHz airspace

• Consistent link quality: stable video + stable control even in harsh RF environments

• Low latency by physics: fiber propagation delay is ~4.9 µs/km (so 30 km ≈ 147 µs one-way) using typical single-mode group index values.

🧱 Built for real field work

• Rugged ABS enclosure with bright length markers (easy ID in the field)

• Sealed-bearing reel + smooth winding to reduce tangles/kinks during payout & retrieval

• Quick-release bulkhead connector for fast setup/teardown

• Optimized form factor for tethered drones, PTZ camera links, and long-range surveillance

🎯 Ideal for

🛡️ Defense trials • 🏭 industrial inspections • 🌲 forest surveillance • 🎥 live broadcast feeds • 🧪 R&D test ranges

🧠 Pro handling tips (prevents 90% failures)

• Don’t “hard kink” the fiber. Bend-insensitive fiber still has limits.

• Keep bends gentle (G.657.A2 design radius is 7.5 mm, but in real field use: bigger is safer).

• Always cap/clean connectors (dust = random video dropouts).

2) 🧵 Fiber Optic Cable Tray (1 km – 30 km) — G657A2 Single-Mode Spool

🔥 What it is

The FlySpark Fiber Optic Cable Tray is a precision-wound G.657A2 single-mode fiber spool designed for ultra-stable long-distance drone video + telemetry (FPV drones, UAV surveillance, ground-to-air optical links).

🧠 What “G657A2” actually gives you (not marketing — real spec)

• Bend-insensitive fiber class, minimum specified bend design radius 7.5 mm

• Designed for use across 1260–1625 nm bands (common single-mode windows)

• Typical attenuation targets for G.657.A2 class fiber: ≤0.35 dB/km @1310 nm and ≤0.21 dB/km @1550 nm (datasheet reference)

✅ Key Features (field-use focused)

• 📏 1 km to 30 km range options

• 💪 High tensile strength >50 N (aerial strain handling)

• 🧲 Aluminium alloy nozzle = smooth payout + less fiber damage

• 🧱 ABS body (1–25 km) + Carbon-fiber shell (30 km) for rugged deployments

• 🔌 FC connector interface, quick reliable attachment

• 🌦️ Outdoor-ready: dust/shock resistant build

⚠️ Blunt correction about your weight list

Your list matches the site perfectly for 1km, 2km, 20km, 25km, 30km — great.
But 3km / 5km / 10km / 15km in your message do NOT match what’s on the product page (example: you wrote 3km = 470g, site says 800g).
So either:

• your list has typos, or

• you’re quoting a different “lite” batch/version.

If you want, I can rewrite this section in a way that avoids publishing the wrong numbers (but I won’t invent correctness).
