MPO 12 Fiber OM1 Trunk Cable

BWN-TK-M12-OM1-OR-B-{JKT}-{LEN} + configuration options

Product Overview

The BWNFiber 12-fiber MPO OM1 trunk cable terminates one MPO-12 PC female connector on each end of a 3.0 mm orange jacket, built as Type B. It serves one job: like-for-like replacement and expansion of installed OM1 62.5/125 μm legacy multimode plants.

OM1 is a legacy fiber grade, and this page deliberately makes no 40G, 100G or 400G claim — it exists so maintenance teams can match the installed base exactly instead of mixing fiber grades on one channel. The official polish name is PC; UPC is a search synonym only. Overall length runs 5-100 m.

Key Features

• One MPO-12/PC female connector on each end
• 12 live fibers, OM1 62.5/125 μm multimode
• Orange jacket per OM1 identification practice
• Type B polarity fixed in the official build
• 3.0 mm round jacket
• 5-100 m standard length set, custom on request
• 100% factory-terminated and optically tested before shipment

Technical Specifications

Final insertion loss and return loss limits follow the BWNFiber test specification for the selected loss grade. Test method reference: IEC 61300-3-4.

Selection Guidance

• Order this page only to match an installed OM1 62.5/125 μm plant. For new builds, OM3/OM4 are the correct multimode grades.
• Polarity is fixed at Type B in this build. Type A and Type C are different builds — request them on the drawing.
• Female (unpinned) ends mate with pinned cassette and panel ports; male (pinned) builds are quoted on request.
• Do not mix OM1 with OM3/OM4 on one channel — the core sizes differ (62.5 vs 50 μm) and the link degrades.
• Jacket by space: OFNP for plenum, OFNR for riser shafts, LSZH for enclosed or public areas.

Applications

• Like-for-like replacement in installed OM1 62.5/125 μm plants
• Legacy multimode backbone maintenance and sparing
• Brownfield expansions that must match the existing fiber grade
• Legacy panel and cassette interconnect

Order Guide

Polarity is already fixed as Type B in this build — choose overall length and jacket. If the site plan calls for Type A or Type C, request that build on the drawing.

Standard lengths: 5, 7, 10, 15, 20, 25, 30, 40, 50, 60, 70, 80, 90 and 100 m. Custom lengths between or beyond these steps are quoted on the drawing.

Why Source from BWNFiber

BWNFiber factory-terminates and inspects every MPO end before shipment, records polarity per order, and can attach IL/RL test reports for project handover. Catalog jackets cover LSZH, OFNP and OFNR; PVC, TPU and PE are quoted on project orders, together with OEM printing and labeling. Legacy-grade assemblies get the same factory termination and test discipline as current grades, so maintenance teams can document like-for-like replacements cleanly. Send the interface, fiber type, jacket and overall length, and BWNFiber returns a build sheet before production.
