DIGITUS Fiber optic DIN rail box DN-963850-4, MM‑OM4, assembled with SC adapter and 2 m pigtail

The DIGITUS Fiber optic DIN rail box DN-963850-4 is a pre-assembled, space-saving enclosure for multimode OM4 fiber cabling. Designed for DIN-rail mounting, it includes SC duplex adapters and a 2 m SC pigtail, providing a ready-to-use solution for fiber distribution and patching in network cabinets, industrial control panels and telecom enclosures. The metal housing and integrated cable management protect fiber connections and help maintain signal integrity while minimising installation time.

Advantages

This assembled DIN rail box is quick to install and reduces setup time by delivering adapters, pigtail and splice capacity in a single unit. Its compact steel housing saves space inside racks and cabinets while offering robust protection. Built-in cable entry options and strain relief help maintain orderly routing and prevent stress on fiber ends, supporting reliable connectivity in industrial and telecommunications environments.

Suitable for

• Multimode OM4 fiber distribution and patching
• DIN-rail mounting in switch cabinets and control panels
• Industrial and telecom enclosures requiring compact fiber management
• Splicing and termination of installation cables up to 12 fibres

When it may not be suitable

This product is intended for multimode OM4 (50/125 µm) fiber and is not suitable for singlemode networks or applications requiring singlemode performance. It also has a limited fibre capacity (up to 12 fibres), so installations requiring higher port counts or large-scale backbone distribution may require a larger panel or cabinet solution.

Key specifications

• Number of connections: 6 (SC duplex)
• Fiber capacity: up to 12 fibres
• Fiber type and class: Multimode OM4, 50/125 µm
• Included adapter: SC duplex with ceramic sleeves
• Included pigtail: SC connector, 2 m length, 0.9 mm diameter
• Suitable for splicing installation cables
• Housing material: Steel
• Colour: Grey (RAL 7035)
• Cable entry: two cable entry openings and one M20 cable gland
• Strain relief: via cable gland
• Operating temperature: -20 °C to 60 °C
• Storage temperature: -20 °C to 60 °C
• Dimensions: 135 x 38 x 141 mm

How to use

Mount the unit on a standard DIN rail inside the cabinet or panel and route incoming fibers through the provided cable entries or the M20 cable gland. Secure fibers with the cable gland for strain relief, perform splicing or termination onto the supplied SC pigtail and place splices into the internal splice tray. Connect external patch cords to the SC duplex adapters to complete the link. The pre-installed components reduce on-site assembly steps.

What to consider before purchase

• Intended fiber type: multimode OM4 (50/125 µm) — not for singlemode use
• Required fibre count — this box supports up to 12 fibres and 6 SC connections
• Mounting environment — requires DIN-rail space inside cabinets or enclosures
• Check whether a metal housing and listed operating temperature range suit the installation site

Usage recommendations

Use clean, factory-standard splicing and termination practices. Route fibers with minimum bend radius in mind, secure the pigtail and cable gland for strain relief, and verify connections with appropriate test equipment after installation to ensure expected performance.
