Price list for high-temperature resistant LPO optical modules for data center interconnection

High-temperature resistant tunable optical modules for data center interconnection range from $2,000 for short-reach 400G modules to over $130,000 for OEM coherent ZR+ modules, with industrial-grade SFP+ and QSFP-DD options available for harsh environments.Overview of High-Temperature Tunable ModulesHigh-temperature or industrial-grade optical transceivers are designed to operate reliably in extreme environments, including outdoor cabinets, vehicles, and unprotected sites, where temperatures can exceed standard data center ranges . These modules maintain data integrity and stable connectivity under thermal stress, vibration, and electromagnetic interference. Common types include:SFP/SFP+: Typically support 1–10 Gbps, widely available in industrial-grade variants, with operating case temperatures often exceeding standard ranges .QSFP28/QSFP-DD: Support 100G–400G, with tunable options for C-band wavelengths (1528–1566 nm) and ±2.5 GHz stability .400G/800G QSFP-DD: Used for high-speed DCI, with prices ranging from $1,400–$1,800 for short-reach SR8 modules to over $130,000 for OEM coherent ZR+ modules .Price RangesShort-Reach 400G SR8 Modules: $1,400–$1,800 from third-party vendors, suitable for in-rack or cross-row connections .DR4/FR4 Modules: Mid-range modules bridging data center rows, with competitive third-party pricing .LR4, ZR, ZR+ Modules: Long-reach coherent optics for DCI, OEM prices can exceed $10,000–$130,000 depending on distance and performance .800G QSFP-DD Modules: Early-stage market, third-party options cost roughly 60–70% of OEM list prices, with thermal and DSP constraints affecting deployment .Industrial-Grade ConsiderationsOperating Temperature: Industrial modules often support -40°C to +85°C or higher, compared to standard 0–70°C ranges .Power & Heat: Modules like SFP+ consume ~0.8–1.2 W; high-density deployments require thermal management to prevent derating .Tunable Features: Tunable SFP+ modules allow wavelength adjustment on the ITU-T 50 GHz grid, supporting flexible channel allocation in DCI networks .Reliability: Industrial-grade modules are tested for vibration, shock, and electromagnetic interference, ensuring uptime in harsh conditions .Vendor OptionsOEMs: Provide high-end coherent optics with guaranteed performance and firmware support, but at premium prices.Third-Party Vendors: Offer cost-effective alternatives for SR8, DR4, and some LR4 modules, often with 30–40% savings compared to OEMs .Specialized Industrial Suppliers: Provide ruggedized SFP/SFP+ and QSFP-DD modules for extreme temperature and vibration environments .SummaryFor data center interconnection requiring high-temperature tunable optics, buyers can expect:Short-reach 400G modules: $1,400–$1,800Long-reach coherent ZR/ZR+ modules: $10,000–$130,000800G QSFP-DD modules: 60–70% of OEM prices for third-party optionsIndustrial SFP/SFP+ modules: Tunable, ruggedized, supporting extreme temperatures and harsh environments Selecting the right module depends on data rate, reach, environmental conditions, and budget, with industrial-grade tunable optics providing resilience and flexibility for challenging DCI deployments .
