• Fire Safety: Cabinet materials shall have a flammability rating of V-0 (per UL 94) or equivalent, minimizing fire propagation risks.

• Low-Voltage Compatibility: If designed to accommodate low-voltage power supplies (e.g., for monitoring equipment), the cabinet shall include separate compartments or cable glands for power and fiber cables, complying with IEC 62208 safety requirements.

5. Fiber Management and Compatibility

5.1 Cable Entry/Exit

• The cabinet shall be equipped with multiple cable entry/exit points (minimum 4) with weatherproof cable glands or grommets, compatible with various cable diameters (e.g., 6 mm to 25 mm). Cable entry points shall be positioned to facilitate organized cable routing and prevent water ingress.

• Entry/exit points shall support both aerial and underground fiber cables, with provisions for strain relief to protect cable terminations from mechanical stress.

5.2 Fiber Compatibility

• Shall support single-mode (SM) and multi-mode (MM) fiber optic cables in accordance with IEC 60793 Series.

• Single-mode fiber compatibility: ITU-T G.652.D, G.657.A1, G.657.A2, G.657.B3

• Multi-mode fiber compatibility: IEC 60793-2-10 OM3, OM4

• Compatible with fiber optic connectors (e.g., SC, LC, FC) and splice trays, with sufficient mounting space for up to [specify maximum number, e.g., 4] splice trays and [specify maximum number, e.g., 8] fiber optic splitters (1x8, 1x16, 1x32 configurations).

5.3 Fiber Protection

• Internal cable management features (e.g., cable guides, tie-down points, slack storage) shall be provided to ensure proper fiber routing and maintain a minimum bend radius of 10 mm for single-mode fibers and 15 mm for multi-mode fibers (during installation) and 7.5 mm for single-mode fibers and 10 mm for multi-mode fibers (in final position) (compliant with IEC 60793-1).

• Splice and connector areas shall be protected from dust, moisture, and physical damage, with optional internal environmental control (e.g., desiccant packs) to maintain dry conditions.

6. Compliance and Testing

6.1 Compliance Verification

• All components and materials of the cabinet shall comply with the requirements of the referenced IEC and Telecordia standards. A compliance certificate shall be provided for each product type, documenting test results and adherence to specifications.

6.2 Test Methods

• Mechanical Testing:

￮ Load-bearing test: Apply 1.5 times the maximum intended load (equipment + cables) to mounting points for 24 hours; verify no permanent deformation.

￮ Impact test: IEC 60068-2-75, 5 J impact energy at critical points (e.g., door, frame); no structural damage or loss of ingress protection.

￮ Vibration test: IEC 60068-2-6, 10 Hz to 500 Hz, 10 g acceleration (peak) for 2 hours per axis; no loosening of components or degradation of performance.

• Environmental Testing:

￮ Temperature cycling: IEC 60068-2-14, -40°C to +65°C, 10 cycles, 1 hour dwell time at each extreme; no condensation or functional issues.

￮ Humidity testing: IEC 60068-2-3, 93% relative humidity, +40°C, 10 days; no corrosion or degradation of materials.

￮ IP rating test: IEC 60529, verify IP55 compliance (dust protection and water jet resistance).

￮ UV exposure test: IEC 60068-2-5, 1000 hours xenon arc exposure; no visible degradation of external surfaces.

• Safety Testing:

￮ Ground continuity test: IEC 60364, verify resistance ≤ 0.1 Ω between grounding point and metal components.

￮ ESD test: IEC 61000-4-2, verify no damage to internal components after contact and air discharge.

7. Marking and Documentation

7.1 Marking
