The Juniper JNP-QSFP28-100G-SR4 QSFP28 transceiver is a high-turnover SKU for our wholesale channel, targeted at resellers, system integrators and IT procurement teams building short-reach 100 Gbps links over multimode fiber. Units ship from stocked inventory with batch-consistent coding and manufacturing dates within the same lot, so projects and recurring orders receive homogeneous modules suitable for mixed deployment across spine-leaf and top-of-rack architectures on Juniper switch platforms.
All shipments are supplied with CE, FCC and RoHS compliance documentation, making the product suitable for export to EU, US and most international markets. Standard warranty terms cover advance replacement RMA handling; defective units are processed through a structured RMA workflow with clear turnaround targets to minimize downtime for your end customers.

Reseller & Integration Guidance
- The 4×25 Gbps parallel-lane design requires an MPO/MTP-12 patch infrastructure on the OM4 side — integrators should verify polarity (Method B/C) and connector cleanliness during rollout, as MPO contamination is the most common cause of SR4 link errors and avoidable RMA claims.
- SR4 occupies the lowest-cost, shortest-reach tier of the 100G family; for quotes involving runs beyond 100 m, position LR4 (single-mode, 10 km class) optics as the upsell alternative.
- Stock is allocated in matched pairs per link (two modules plus MPO trunk or cassette cabling). Specify original, Juniper-coded, or compatible-coded units when placing volume orders so each batch meets your switch vendor’s coding policy and your end-client requirements.
