Buying Guide

Choose the correct fiber type

For short to medium building-to-building distances, multimode OM3 is common—confirm your transceivers and switches support OM3 multimode performance

Connector compatibility

Pick LC-to-LC connectors if your equipment uses LC ports; using matching connector types avoids adapters and insertion loss

Select appropriate length and packing

Measure conduit route with slack for bends and future moves; multi-packs (10-pack options) offer consistency and spare cables for redundancy

Jacket and durability for conduit runs

Look for rugged outer jackets rated for conduit pulling, low-smoke/zero-halogen or riser/LSZH where required by local codes to protect fibers during installation

Verify bandwidth and insertion loss specs

Confirm OM3 bandwidth (50/125 µm) supports your target data rate (e.g., 10 Gbps) and check vendor test results for insertion loss and return loss to ensure link budget
