Intel LTF8505-BC-IN / E25GSFP28SR 25G SFP28 SR Multimode Optical Transceiver
SKU: 4637
The Intel LTF8505-BC-IN (boxed retail SKU: E25GSFP28SR) is a 25GBASE-SR SFP28 short-reach transceiver engineered for multimode fiber links in data center and enterprise Ethernet environments. For our B2B channel partners—resellers, system integrators, and IT procurement teams—this module is a high-turnover item for deployments pairing 25G top-of-rack switches with servers fitted with Intel XXV710 or E810 network adapters. Its native 10GbE backward compatibility makes it a practical line item for phased network upgrade projects.
We supply this model from ongoing stock with batch consistency guaranteed: units within a single purchase order ship from the same manufacturing lot to ensure uniform firmware coding and performance characteristics across your deployment. Please verify that your fiber plant is OM3, OM4, or OM5 grade before placing volume orders, as the 70 m (OM3) and 100 m (OM4/OM5) reach figures apply only to those cable grades.

Supply & Channel Information
Stock and lead times. This SKU is stocked on a rolling basis for repeat wholesale orders; current on-hand quantity is confirmed at quotation. Standard orders typically dispatch within 1–3 business days of payment confirmation. Larger project volumes may require partial allocation—our sales team will confirm firm delivery schedules before order commitment, and we can hold reserved stock for integrators running staged rollouts.
Warranty and RMA. All units ship with a full replacement warranty. Defective modules reported within the RMA window are replaced from stock or credited against future orders, with dedicated after-sales handling for channel partners to minimize downtime on customer sites.
Export compliance. The LTF8505-BC-IN carries CE, FCC, and RoHS certifications, and all shipments include the documentation required for export clearance. We ship worldwide from bonded warehouses with commercial invoices, packing lists, and certificates of origin available on request for your customs broker.
Reseller and integrator suitability. Because this module conforms to the SFP28 MSA and IEEE 802.3by, it integrates cleanly into multi-vendor 25G infrastructures. Note that certain switch vendors enforce firmware-coded transceiver whitelists—our technical team can advise on platform compatibility before you commit to volume, helping you avoid costly returns on customer deployments. Within Intel’s optical portfolio, this SR variant offers the lowest power draw (≤ 0.3 W) and landed cost, making it an attractive margin item for in-rack and adjacent-rack links; for longer runs, pair it with LR-class single-mode SKUs from our catalog. For pricing on project quantities, request a wholesale quote.
