Outdoor IP68 Fiber Optic Splice Closure Lightwin FOCUS-CODC2-AA — up to 144 fibers

Lightwin FOCUS-CODC2-AA is an outdoor IP68-rated fiber optic splice closure designed to protect and organize splices for up to 144 fibers. Built for use in aerial, duct and underground installations, the closure provides environmental sealing, secure cable entry points and internal fiber management that supports long-term network reliability in FTTH, access and distribution networks.

Advantages

The enclosure delivers IP68-level protection against dust and water ingress and a compact, corrosion-resistant housing suitable for varied outdoor conditions. Internal trays and splice holders support orderly routing and protection of fusion splices, while multiple cable entry ports allow different cable types and directions to be managed within the same closure. The design facilitates re-entry for maintenance without compromising the sealing system.

Suitable for

• Outdoor aerial cable joints
• Duct and underground splicing points
• Distribution cabinets and pedestal connections
• FTTH, access and metropolitan distribution networks
• Temporary or permanent repair and branching of fiber runs

Key specifications

• Protection rating: IP68 for dust and water resistance
• Fiber capacity: up to 144 fibers
• Material: UV-stable, corrosion-resistant thermoplastic housing
• Mounting options: aerial, duct and underground installations
• Cable ports: multiple sealed entry points for different cable diameters
• Internal: splice trays and holders for organized fiber routing
• Re-entry: designed for maintenance access without degrading the seal

How to use

Prepare fiber ends according to standard fusion splice procedures and place fusion splices into the provided splice holders or trays. Route incoming and outgoing cables through the appropriate sealed ports and secure them with the built-in clamping system to maintain strain relief. Arrange fibers on the trays to respect the minimum bend radius and close the enclosure, ensuring seals and gaskets are seated correctly to restore IP68 protection. Follow local installation regulations and test splices with an optical power meter or OTDR after assembly to verify performance.

Usage recommendations

For long-term reliability, store and install the closure in locations that avoid prolonged standing water when possible, and ensure correct cable support to prevent mechanical stress. Use compatible heat-shrink protectors and splice holders from the same product family to maintain organized splicing. Periodically inspect seals after extreme weather events and retest optical performance following maintenance operations.
