Product Overview
GPJ09-9401 Fiber Optic Inline Splice Closure is a member in dome series, the main function is to provice direct pass, branch and splice protection for various types of fiber cable during optical transmission.
Protection rate is IP68. This type has two round cable ports and one oval cable port for uncut fiber cable. The material of seal component is vulcanized rubber, the cables and the closure are sealed in a mechanical way with the help of compacting pressure from the plastic screws.This model is excellent in sealing performance, easy for installation, wide applications.

Key Features
GPJ09-9401 Fiber Optic Inline Splice Closure boasts excellent re-encapsulation performance and is easy to operate. Its sealing performance is verified by inflation pressure testing. It is suitable for loosely shielded optical cable, tight-jacketed cable, central tube jacketed cable, and others, with an inlet cable diameter range of 7-17.5mm and an uncut cable diameter range of 11.5-17.5mm. The outlet cables can be various soft cables. The closure provides functions for fixing the strength member of fiber cable and armored cable, as well as grounding. It offers reasonable cable routing for uncut cable, splitter cable, and splicing cable, with a minimum bend radius of ≥30mm. Installation is versatile, supporting pole mounting, wall mounting, aerial, direct buried, and pipe-lined methods.

Industry application scenarios and solutions




Internal Structure
Specifications

The GPJ09-9401 closure has dimensions of 295 x 220 x 90 mm and weighs between 2.0 to 2.3 kg. It supports a maximum capacity of 48 fibers (according to Doc1) or 36 fibers (Doc2), and is compatible with 1x 1x8PLC or 1x 1x16PLC splitters.
The sealing type is mechanical, and it features 3 cable ports: 1 oval port for uncut cable and 2 round ports for branching or soft cable. The suitable cable diameter ranges from 8-17.5 mm for round ports and 10-17.5 mm for oval ports. It can accommodate up to 3 splice trays, each with a capacity of 12 fibers.
The operating environmental temperature ranges from -40℃ to +65℃. Insulation resistance is ≥2x10⁴ MΩ, and it withstands voltage up to 15KVDC for 1 minute without arc-over or puncture. Sealing performance is verified by inflation pressure testing at 100KPa, immersed in water for 15 minutes with no bubbles, or no change in barometer after 24 hours. Re-encapsulation performance meets standards after 3 re-entry cycles.
