Overview
TMT Global 24 Fibre Heat-Shrink Dome Closure Series
The TMT Global 24 Fibre Heat-Shrink Dome Closure is a passive optical network enclosure for protected fibre splicing, routing and storage in aerial deployments. The TMT-24-D-A-4-H-N is configured for up to 24 fibres with 4 nominal cable-entry ports, heat-shrink sealing and dedicated splice-management capacity. The closure is intended for telecom, FTTH, campus, CCTV and structured fibre infrastructure where controlled bend radius, cable strain relief and service access are required.
KEY FEATURES

- OEM / PUBLICATION POSITIONING
Installation shall maintain minimum fibre bend radius, cable strain relief, splice protection and sealing integrity. OEM shall submit the production drawing, tray arrangement, supported cable-diameter range, material declaration, dimensional tolerances, sealing/IP test evidence where claimed, temperature/environmental qualification, packaging specification and pre-production sample for TMT approval. No change to TMT-24-D-A-4-H-N construction or declared capacity is permitted without TMT approval.
- STANDARDS / TEST BASIS
- IEC 61758 series — fibre optic interconnecting devices and passive components: closures
- IEC 61300 series — basic test and measurement procedures for fibre optic interconnecting devices/passive components
- IEC 60529 — ingress protection classification where an IP claim is declared
Applications — Continued
- ISO/IEC 11801 / EN 50173 — structured cabling system application context
- RoHS / REACH declarations for supplied materials where applicable
