Price list for 100GOLT optical line terminals for data center interconnection

100G optical line terminals (OLTs) and QSFP28 transceivers for data center interconnect typically range from $280 to over $2,200 per module, depending on vendor, reach, and form factor.QSFP28 100G Transceiver PricingShort-Range (SR4) Modules: Third-party QSFP28 SR4 modules can cost around $35 per module, equating to $0.35 per Gbps . These are suitable for multimode fiber links up to 100 meters and are ideal for intra-data center connections .Long-Range (LR4) Modules: OEM LR4 modules can cost $2,200 per module, while compatible third-party LR4 modules are available for $280 per module, supporting single-mode fiber links up to 10 km . LR4 modules are commonly used for cross-site data center interconnects.Extended Reach (ER4, ZR4, CWDM4): Prices vary significantly depending on distance and vendor support. These modules are designed for longer single-mode fiber links, often exceeding 40 km, and may cost several thousand dollars per module for OEM options .Optical Line Terminals (OLTs)Vendors like FS offer high-quality GPON, EPON, and XG(S)PON OLTs suitable for high-speed optical networks . While specific 100G OLT pricing is not listed, costs generally scale with port density, reach, and vendor support. For planning purposes, expect enterprise-grade 100G OLTs to range from several thousand to tens of thousands of dollars per chassis, depending on configuration and number of 100G ports.Considerations for ProcurementOEM vs Third-Party Modules: OEM modules guarantee full vendor support but are significantly more expensive. Third-party modules can offer up to 80% cost savings while maintaining compatibility, provided they are tested for your specific switch platforms and firmware .Reach and Fiber Type: Choose SR4 for short multimode links, LR4 for 10 km single-mode, and ER4/ZR4 for extended distances. Ensure the OLT or switch supports the selected module type.Volume Discounts: Large-scale deployments can reduce per-module costs, especially for third-party transceivers.Testing and Certification: Always pilot third-party modules to verify interoperability, link stability, and monitoring features before bulk purchase.SummaryFor 100G data center interconnect, expect:QSFP28 SR4: ~$35/module (short-range, multimode)QSFP28 LR4: $280/module (third-party) to $2,200/module (OEM, 10 km single-mode)ER4/ZR4/CWDM4: Several thousand dollars per module for extended reach100G OLT chassis: Several thousand to tens of thousands of dollars depending on port count and vendor Selecting the right combination of OLT and transceivers depends on distance, fiber type, vendor support, and budget, with third-party QSFP28 modules offering significant cost savings for large-scale deployments.
