Price List for 100G Enterprise-Grade Optical Routers for Data Center Interconnection

100G QSFP28 optical transceivers for data center interconnect range from $35 for short-reach third-party modules to over $2,000 for OEM long-reach modules, with significant cost savings possible using qualified third-party optics.Overview of 100G Optical Modules100G optical transceivers, typically in QSFP28 form factor, are widely used for data center interconnect (DCI), supporting high-bandwidth, low-latency, and long-distance links between distributed facilities . They come in various types based on reach and fiber type:SR4 (Short Reach): Multi-mode fiber, up to 100m, MPO connector, ideal for intra-data center links .LR4 (Long Reach): Single-mode fiber, up to 10km, duplex LC connector, suitable for cross-site DCI .ER4/ZR4: Extended reach, up to 40–80km, for long-distance interconnects .CWDM4/DR: Cost-effective options for medium-range single-mode links .Pricing ExamplesThird-Party QSFP28 SR4 Modules: Around $35 per module, equating to $0.35 per Gbps . These are suitable for short-reach intra-data center connections.OEM LR4 Modules: Can cost $2,200 per module, providing guaranteed compatibility and support for 10km single-mode fiber .Third-Party LR4 Modules: Compatible alternatives are available for $280 per module, offering the same 10km reach and warranty, with proper testing ensuring reliability .Cisco 100G Modules: Pricing varies by type (SR4, LR4, ER4, ZR, CWDM4) and platform compatibility. Volume discounts are often available for purchases of 100 units or more .Cost ConsiderationsOEM vs Third-Party: OEM modules provide guaranteed support and platform coding, while third-party modules offer substantial cost savings but require testing for compatibility .Volume Discounts: Large-scale purchases can significantly reduce per-unit costs, especially for Cisco and other major vendors .Reach Requirements: Short-reach modules are much cheaper than long-reach or extended-reach modules, so selecting the correct type for your DCI distance is critical .RecommendationsAssess Link Distance: Choose SR4 for intra-data center, LR4 for cross-site up to 10km, and ER4/ZR4 for longer distances.Consider Third-Party Modules: For large deployments, properly tested third-party LR4 modules can save over 80% of optics costs .Check Vendor Compatibility: Ensure modules are MSA-compliant and tested on your switch/router platforms to avoid operational issues.Plan for Volume Discounts: Contact vendors like Cisco for bulk pricing if purchasing 100+ units . By carefully selecting module type, vendor, and volume, data center operators can optimize both performance and cost for 100G interconnects.
