The Intel LTA8531-PE-IN is a 100GBASE-SR4 QSFP28 multimode optical transceiver stocked for volume procurement by resellers, system integrators and data center project buyers. It is positioned for short-reach parallel-optics links over OM4 multimode fiber using MPO/MTP-12 patching, making it a recurring line item for rack-scale and in-row deployments where predictable supply and consistent builds matter more than single-unit purchases.
Units are supplied in sealed manufacturer packaging with consistent date codes within each batch, so integrators deploying across multiple switches or sites receive matched hardware. Inventory levels on this SKU fluctuate with demand; current on-hand quantity and allocation for large orders should be confirmed before committing delivery schedules to your end customers. Sample units for compatibility validation are available to qualified trade buyers prior to bulk commitment.
All shipments are dispatched with export documentation suitable for CE/FCC/RoHS-regulated markets, and the module conforms to the QSFP28 MSA and IEEE 802.3bm as noted below. Each unit is covered by a standard wholesale warranty with an RMA process handled directly through our trade desk — defective units reported within the RMA window are replaced or credited without requiring individual end-user claims. Standard lead time for in-stock quantities is typically short; confirmed orders receive a binding ship date at quotation.
Note that some switch vendors enforce coded or whitelisted optics policies; integrators should verify third-party optics acceptance on the target platform before placing volume orders. For deployment planning, remember SR4 requires a matching SR4 transceiver at the far end and quality MPO/MTP multimode patch cables — we can quote matched pairs and cabling alongside the transceivers.

Good to know for integrators
- Compatibility: as an MSA-based 100GBASE-SR4 module, it generally interoperates with QSFP28 SR4 ports on mainstream data center switch platforms; verify the host switch’s third-party optics policy to avoid RMA friction on restricted platforms.
- Family positioning: SR4 is the lowest cost-per-port 100G short-reach option over multimode fiber, complementing longer-reach single-mode alternatives (PSM4, LR4); the ≤ 2.5 W 4 × 25 Gbps NRZ/VCSEL design suits dense-switch thermal budgets in volume rollouts.
- Deployment tip: order matched pairs and quality MPO/MTP-12 multimode patching with each batch, and use DOM/DDM telemetry to validate link budgets at acceptance testing before site handover.
