Fiber optic splice box Lightwin SPBOX 48G50 OM4 — 48 fibers, 24× DLC multimode 50/125µm OM4

Lightwin SPBOX 48G50 OM4 is a fiber optic splice box designed to organize, protect and manage up to 48 multimode fibers in a compact indoor enclosure. The unit provides 24 DLC multimode 50/125 µm OM4 adapter positions and dedicated splice trays, allowing orderly routing and secure splicing of multimode links. It supports neat cable entry and exit points for feeder and distribution cables, enabling clean installation in data center cabinets, telecommunications rooms and building backbones where OM4 multimode performance is required.

Advantages

The enclosure combines high-density connector capacity with structured fiber management to reduce signal loss and maintain bend radius control. Designed for multimode OM4 applications, it supports consistent insertion loss and return loss when used with compatible connectors and patch cords. Sturdy splice trays and secure adapter positions protect splices and connectors from mechanical stress while facilitating future moves, adds or changes. The compact footprint allows installation in confined equipment racks or wall-mounted panels.

Suitable for

• Data center intra-rack and inter-rack multimode connections
• Building backbone and riser cabling using OM4 multimode fiber
• Horizontal cabling to consolidation points and telecom outlets
• Patch panel and consolidation enclosure installations

Key specifications

• Fiber capacity: up to 48 multimode fibers
• Connector positions: 24 DLC multimode 50/125 µm OM4 adapter slots
• Fiber type supported: OM4 multimode 50/125 µm
• Splice management: multiple splice trays for fusion or mechanical splices
• Cable entry: dedicated entry/exit points for feeder and distribution cables
• Mounting: rack or wall-compatible compact enclosure

How to use

Install the splice box at the planned mounting location and secure it according to rack or wall-mount instructions. Route incoming feeder and outgoing distribution multimode cables through the designated entry points, observing proper outer jacket preparation and buffer tube handling. Place fibers into the provided splice trays and perform fusion or mechanical splices, then secure splices in the tray to maintain bend radius and prevent movement. Terminate connectorized pigtails into the 24 DLC OM4 adapter positions and use appropriate OM4 patch cords for connections. Close the enclosure ensuring cable strain relief and protective covers are in place.

Usage recommendations

Use OM4-rated patch cords and pigtails to preserve multimode performance. Maintain recommended minimum bend radii for 50/125 µm multimode fiber during routing and within splice trays. Label adapter positions and splice trays for easier identification and future maintenance. Perform insertion loss and continuity testing after splicing and before putting links into service.
