Relay Protection QSFP Optical Module LPO Price Quotation

QSFP-DD Linear Pluggable Optical (LPO) modules typically range from $1,400 to over $130,000 depending on type, reach, and vendor, with third-party modules offering cost-effective options for relay protection and data center applications. Overview of QSFP-DD LPO ModulesQSFP-DD LPO transceivers are designed for low-latency, high-bandwidth optical links, supporting PCIe Gen 5. 0 and scalable server disaggregation.

They are ideal for rack-to-rack interconnects, AI/ML workloads, and relay protection systems where fast, reliable optical communication is critical (Amphenol). Key features include: 8-channel full-duplex operationReach up to 50 metersPower consumption under 5WHot-pluggable form factorPricing ConsiderationsThe cost of QSFP-DD LPO modules varies widely based on module type, transmission distance, and vendor: Short-reach SR8 modules for in-rack connections: approximately $1,400–$1,800 from reputable third-party vendors. Long-haul coherent ZR+ modules for data center interconnects: can exceed $130,000 from OEMs.

Intermediate DR4 and FR4 modules bridge data center rows or campus links, with prices typically between the SR8 and ZR+ ranges. Third-party vendors like AscentOptics offer LPO modules optimized for minimal power, cost, and latency, providing a cost-effective alternative to OEM products.

Procurement Tips

Define your reach and bandwidth requirements: Short-reach modules are significantly cheaper than long-haul coherent optics. Consider third-party modules: They often provide substantial savings without compromising performance. Check volume discounts: Many vendors offer tiered pricing for bulk purchases.

Verify compatibility: Ensure the module supports your relay protection or data center equipment. For a precise quotation, it is recommended to contact vendors directly such as Amphenol, AscentOptics, or FS.com, providing your required module type, reach, and quantity to receive an official price quote.
