The ZC-FV109M is a high-capacity vertical fiber optic splice closure designed for outdoor fiber splicing, storage, and long-term protection.
With IP68 protection, PP housing, and a mechanical sealing (M) structure, it supports repeatable opening and re-sealing—reducing lifecycle risk when networks expand over time.
| Item | Specification | Decision / Risk Note |
|---|---|---|
| Model | ZC-FV109M | Mechanical seal type “M” supports repeatable re-entry maintenance. |
| Color | Black | Outdoor-friendly; helps hide dirt and UV discoloration. |
| Protection Level | IP68 | Recommended for manhole/duct/high moisture environments. |
| Material | PP (engineering plastic) | Corrosion-resistant; stable mechanical structure for outdoor use. |
| Sealing Method (Inlets) | Mechanical seal (M) | Faster install, lower tool dependency, consistent sealing quality. |
| Inlet / Outlet | 2 + 8 | Supports loop-through trunk (2) + multiple distribution branches (8). |
| OD of Ports | 2 big round ports: 25 mm 8 small round ports: 18 mm |
Engineer checkpoint: cable OD must match port OD to prevent leaks and strain. |
| Operating Environment | Temperature: −40℃ ~ +60℃ Humidity: ≤95% (at 40℃) Pressure: 70 kPa ~ 106 kPa |
Suitable for harsh climates; standardize SOP for extreme cold/heat days. |
| Dimension | 530 × 305 mm | Check cabinet/manhole clearance before mass deployment. |
ZC-FV109M supports flexible capacity plans using 24-core or 48-core booklet-style splice trays.
Choose the tray plan based on re-entry frequency and how you stage network expansion.
| Target Capacity | Tray Plan | When to Use |
|---|---|---|
| 96 Cores | 48C × 2 pcs | Fast deployment, fewer parts; stable access nodes with lower re-entry. |
| 96 Cores | 24C × 4 pcs | Better control for staged rollout and frequent add operations. |
| 144 Cores | 48C × 3 pcs | Balanced density and maintenance for distribution points. |
| 144 Cores | 24C × 6 pcs | Best for frequent re-entry with minimal splice disturbance. |
| 288 Cores | 48C × 6 pcs | High-density branching or future-proofing where upgrades are costly. |
Mechanical sealing improves field repeatability by reducing heating-tool dependency and enabling consistent re-sealing during upgrades.
The internal trays are turn-able like a booklet, allowing technicians to operate cables and fibers individually while keeping routing organized.
Use this quick comparison to choose capacity and tray strategy while controlling cost, risk, and maintenance time.
The goal is to prevent underbuild (forced redesign) and avoid port/cable mismatch (sealing failures).
| Decision Factor | Choose 96 Cores | Choose 144 Cores | Choose 288 Cores |
|---|---|---|---|
| Growth expectation (12–24 months) | Low to moderate growth; stable access points | Moderate growth; distribution nodes | High growth; upgrade cost higher than initial overbuild |
| Re-entry frequency | Occasional | Regular | Frequent + branching changes |
| Tray recommendation | 48C×2 for speed 24C×4 for control |
48C×3 balanced 24C×6 for staged rollout |
48C×6 for future-ready density |
| Primary risk to manage | Underbuild (future capacity short) | Maintenance time + staged expansion | Complexity control + long-term lifecycle cost |
| Cost/Risk Driver | What It Impacts | How to Control It |
|---|---|---|
| Port OD mismatch (25/18 mm) | Sealing failure, cable strain, water ingress | Confirm cable OD range in BOM; sample-fit before rollout |
| Re-entry workload | Truck rolls, downtime, OPEX | Mechanical seal + 24C trays when frequent adds are expected |
| Capacity underbuild | Forced redesign and replacement | Plan 12–24 months growth; consider 144/288 at high-growth nodes |
| Scenario | Why ZC-FV109M Fits | Recommended Setup |
|---|---|---|
| ODN loop-through distribution | 2 main entries support trunk pass-through; 8 branches support drops | 144 cores + 24C trays for staged expansion and clean re-entry |
| Outdoor access nodes (FTTH/FTTB) | IP68 protection, reliable housing, convenient maintenance | 96 cores + 48C trays for fast deployment |
| High-growth service areas | Big capacity reduces future redesign and node replacement | 288 cores + 48C trays for future-ready density |
| Manhole / duct environments | IP68-rated sealing supports high moisture and dust | Commission with seal + insulation checks; verify port OD mapping |
Use the following acceptance checks to validate sealing, safety, and fiber routing performance during commissioning.
These checks reduce post-install failures and improve long-term maintainability.
| Test / Requirement | Target | Why It Matters |
|---|---|---|
| Seal performance | After sealing: inflate to 100 kPa, soak in water, observe 15 minutes — no bubbles | Direct indicator of sealing integrity and installation quality |
| Insulation resistance | > 20 kMΩ between metal work piece and earth | Electrical safety and fault risk reduction |
| Pressurization withstand | No breakdown or flashover under DC 15 kV / 1 minute | Improves reliability in complex outdoor environments |
| Fiber bend radius | Curvature radius ≥ 40 mm inside tray, without extra loss | Prevents micro-bending loss and long-term attenuation growth |
| Axial tensile strength | ≥ 1000 N | Reduces risk from pulling forces during installation |
| Service life | 25 years | Lifecycle planning for long-term network assets |
| Item | Value | Planning Note |
|---|---|---|
| Product Dimension | 530 × 305 mm | Confirm clearance in cabinet/manhole and mounting space. |
| Carton Size | 60 × 47 × 50 cm | Useful for container loading and site storage planning. |
| Gross Weight / Carton | 18 kgs | Plan safe handling; confirm courier limits if applicable. |
| PCS / Carton | 4 pcs | Set spare ratio by node criticality and maintenance frequency. |
The ZC-FV109M vertical splice closure delivers a strong balance of IP68 protection, mechanical sealing consistency, and high-capacity tray scalability (96/144/288 cores).
For a reliable outcome, standardize your selection using three steps: (1) confirm 2+8 entry topology fits your distribution plan, (2) verify 25 mm / 18 mm port OD matches your cable OD, and (3) choose 24C vs 48C trays based on re-entry frequency and maintenance SOP.
