Myanmar SFP Optical Module QSFP-DD

QSFP-DD modules enable high-speed 400G and 800G optical connectivity, while SFP modules support lower-speed, flexible network links.QSFP-DD Optical ModulesQSFP-DD (Quad Small Form-Factor Pluggable Double Density) modules are designed for ultra-high-speed networking, supporting 400G and 800G Ethernet connections. They double the number of high-speed electrical interfaces compared to standard QSFP modules, allowing eight independent full-duplex channels with up to 50 Gbps per channel, aggregating to 400 Gbps per module (MikroTik DDQ+85MP01D) . QSFP-DD modules are widely used in data centers, metro, regional, and DCI networks, offering short-range multimode, coherent DWDM, and 2x100G single-mode fiber options . Key features include:Digital diagnostics (DOM) for monitoring optical power, voltage, temperature, and laser bias current .MTP/MPO connectors with Type-B polarity for high-density fiber connections .Flexible deployment for short-range in-rack connections or long-haul DCI links .Security and interoperability, including AES-256 encryption and Open ROADM compliance for multi-vendor networks .SFP and SFP+ ModulesSFP (Small Form-Factor Pluggable) modules are compact transceivers supporting data rates up to 4.25 Gbps, ideal for legacy or low-bandwidth environments. SFP+ is an enhanced version supporting 10G Ethernet, balancing performance and cost for enterprise upgrades . These modules are widely used for flexible, cost-effective network expansion and are compatible with a variety of switches and routers.OEM vs Third-Party QSFP-DD ModulesOEM modules (e.g., Cisco, Huawei) are typically more expensive, especially for long-reach coherent optics like LR4, ZR, and ZR+, which can exceed $10,000 per module .Third-party modules offer significant cost savings, often 60–70% of OEM prices for 400G and 800G transceivers, while maintaining reliability for most enterprise and data center applications .Short-reach SR8 modules are the most common for in-rack connections, priced between $1,400–$1,800 from reputable third-party vendors .Deployment ConsiderationsTransmission distance: Choose SR, DR, FR, LR, or ZR modules based on in-rack, campus, or long-haul requirements .Compatibility: Ensure switch or router supports QSFP-DD or SFP/SFP+ modules.Monitoring: Use DOM features to track performance and schedule maintenance proactively .Security: For sensitive networks, consider modules with AES encryption and Open ROADM compliance . In Myanmar, sourcing OEM QSFP-DD modules may be costlier, but third-party alternatives provide a practical solution for high-speed 400G/800G deployments while maintaining interoperability and reliability.
