Fiber optic trunk cable BlueOptics MPO/UPC OM4 12F Type B 2 m LSZH

BlueOptics MPO/UPC OM4 12F Type B trunk cable is a 2 meter multimode fiber assembly with an LSZH outer jacket, designed for high-density data centre and enterprise fibre runs. The cable terminates in a 12-fibre MPO/UPC connector wired in Type B polarity and uses OM4 multimode fibres to support low-loss transmission for parallel optics and trunking between MPO/MTP panels, cassettes or switches. With a compact MPO footprint and a fire-safe low-smoke zero-halogen jacket, this trunk cable targets short- to mid-range links and multi‑lane 10/40/100G applications where predictable multimode performance and easy rack-side routing are required.

Advantages

The cable combines OM4 multimode performance with an MPO/UPC 12-fibre termination in Type B polarity to enable parallel optical connections with consistent insertion loss and return loss characteristics. Its 2 m length is suited for trunking between adjacent racks or patch panels, while the LSZH jacket reduces toxic and corrosive gas emission in case of fire. The compact MPO connector and factory-polished UPC endfaces simplify installation and reduce the need for field termination, delivering repeatable optical performance in dense cabling environments.

Suitable for

• Data centre trunking between MPO/MTP panels, cassettes or switch ports
• Parallel optics applications such as 40GBASE-SR4 and 100GBASE-SR10
• High-density patching in equipment rooms and server racks
• Short- to mid-range multimode links within enterprise networks

When it may not be suitable

This trunk cable is intended for multimode OM4 environments and will not provide expected performance for single-mode networks or long single-mode links. It is a preterminated MPO/UPC assembly, so it is not appropriate where individual fibre terminations or custom field splicing are required. Also, the 2 m length is optimized for nearby panel-to-panel connections and may be too short for runs between widely separated racks or rooms.

Key specifications

• Fibre type: OM4 multimode
• Connector: MPO/UPC, 12 fibres, Type B polarity
• Length: 2 m
• Jacket: LSZH (Low Smoke Zero Halogen)
• Application: Parallel optics and trunking for 10/40/100G short-to-mid-range links

How to use

Route the BlueOptics MPO/UPC OM4 trunk cable between the two MPO-enabled panels or switch ports, avoiding tight bends and securing the cable to rack management hardware as needed. Align the MPO connector keying according to Type B polarity requirements and insert fully into MPO adapters or cassettes until the latch clicks. If necessary, use MPO polarity verification tools or a light source and power meter to confirm correct channel mapping before placing the link into production. Do not attempt field polishing of the MPO endfaces; if contamination is suspected, clean with an approved fibre connector cleaner before mating.

What to consider before purchase

• Confirm the network uses multimode OM4 fibre and supports MPO/UPC 12-fibre Type B polarity.
• Check that a 2 m trunk length is sufficient for planned panel-to-panel or switch-to-panel routing.
• Ensure MPO adapters, cassettes or switches are compatible with MPO/UPC connectors and Type B wiring.
• Plan for proper cable management and bend-radius control in racks and pathways.

Usage recommendations

For reliable operation, clean MPO/UPC endfaces before each mating, maintain recommended bend radius for multimode fibre, and verify channel mapping for parallel optics links. Use the 2 m OM4 trunk cable for high-density, short-distance interconnects where MPO-based patching simplifies rack-side cabling.
