Fiber splice box Lightwin SPBOX 48G50 OM4 — 48 fibers, 24x DSC ports, Multimode 50/125µm OM4

Lightwin SPBOX 48G50 OM4 is a compact fiber splice box engineered to organize and protect up to 48 multimode optical fibers in 50/125µm OM4 networks. The unit provides 24 external DSC-style ports while securing fusion splices and enabling neat routing of incoming and outgoing fiber cables. Designed for distribution points, telecom cabinets and data centre patching areas, this splice box supports orderly cable management, reduces the risk of fiber damage and simplifies ongoing maintenance tasks.

Advantages

The enclosure offers a dedicated splicing area with secure splice holders and internal routing channels that preserve minimum bend radius and prevent microbends. Its 24 external DSC ports allow convenient connection to patch panels or pigtails without exposing splices. The unit’s layout supports clear separation of incoming and outgoing fibers and provides storage for excess length, facilitating quicker service and lower risk during rework. Materials and construction are chosen to withstand typical indoor telecom environments.

Suitable for

• Data centre fiber distribution and patching
• Telecom rack and cabinet installations
• Horizontal and vertical fibre run terminations
• Multimode OM4 campus and enterprise networks

Key specifications

• Capacity: up to 48 optical fibers
• External interfaces: 24 DSC-style ports for connections
• Fiber type supported: multimode 50/125 µm OM4
• Splice method: fusion splicing with dedicated splice holders
• Fiber management: internal routing channels and slack storage
• Installation: suitable for wall, rack or cabinet mounting
• Construction: indoor-rated enclosure materials for telecom use

How to use

Mount the Lightwin SPBOX 48G50 OM4 in the desired cabinet or on a wall following site requirements and secure it with appropriate fasteners. Prepare incoming and outgoing multimode fibers, strip and clean fiber ends, and perform fusion splicing according to standard procedures. Place each fusion splice into the provided splice holders, route fibers through the internal channels to maintain bend radius, and store excess slack in the designated loops. Connect external multimode patch cords or pigtails to the DSC-style ports to complete connections and label ports for identification.

Usage recommendations

Use compatible OM4 multimode patch cords and ensure fusion splices are protected with heat-shrink sleeves or splice protectors. Maintain recommended bend radii during routing, avoid sharp bends and secure cables to minimize mechanical stress. Perform optical testing after installation to verify loss and continuity and keep the enclosure accessible for future maintenance while ensuring a dust-free environment.
