MPOFiber Optic Loopback Module — 12 & 24 Fiber, OM3/OM4/OS2
MPO/MTP fiber optic loopback module for high-density multi-fiber testing. Available in 12-fiber and 24-fiber configurations with OS2 single mode, OM3, and OM4 multimode options. Designed for QSFP+ module verification, 40GbE/100GbE link testing, and data center parallel optics diagnostics.
Technical Specifications
Engineered For Performance
High-Density Multi-Fiber Testing
Loops back all 12 or 24 fibers simultaneously through a single MPO/MTP connector, enabling rapid verification of high-density trunk cables and cassettes.
Multi-Fiber-Mode Options
Available in OS2 single mode for long-haul links, OM3 for 10G/40G multimode, and OM4 for extended-reach 40G/100G parallel optics applications.
Precision Mechanical Construction
Precision-molded MPO/MTP ferrule with guide pin alignment ensures accurate multi-fiber core alignment for consistent test measurements across all fiber channels.
QSFP+ / QSFP28 Compatible
Designed to mate directly with QSFP+ and QSFP28 MPO interfaces for quick transceiver validation without requiring a full fiber link installation.
Typical Applications
Data Center Link Verification
Validate 40GbE and 100GbE parallel optic links in leaf-spine and top-of-rack architectures by looping MPO trunk connections back at the far end.
QSFP+ Module Testing
Perform transmit-to-receive loopback testing on QSFP+, QSFP28, and QSFP-DD transceiver modules for power level, BER, and link-up verification.
MPO Trunk Cable Acceptance
Use loopback modules during fiber plant installation to confirm all fiber channels in MPO/MTP trunk cables meet insertion loss and continuity requirements.
