- Product Introduction

3/3-Port Inline Fiber Optic Closure
Professional-grade fiber optic closure with 48-288 core capacity. IP68 rated for maximum protection in outdoor environments. Ideal for FTTH, FTTB, and FTTX network applications.
The 3/3 port Inline Fiber Optic Splitter Closure is a powerful solution designed to protect fiber optic connectors in different telecommunications networks. Its design takes into account both performance and flexibility, effectively protecting the joint from extreme weather conditions while ensuring user-friendly installation and maintenance.
This housing is made of high-grade ABS plastic with built-in UV resistance, providing reliable outdoor operation for a long time. Despite its space-efficient dimensions (525mm × 245mm × 150mm), it accommodates a large capacity - whether installed on a utility pole, underground or overhead.
Certified with IP68 rating, it completely blocks dust particles and can withstand long-term immersion in water, performing exceptionally well in harsh environments. The 3-input / 3-output port layout offers flexible cable management and supports multiple network configurations
