Inquire about 40G optical transceiver module

40G optical modules are high-speed, hot-pluggable transceivers that aggregate four 10Gbps channels into a single 40Gbps link, supporting short- to long-range connectivity in data centers and enterprise networks.Key FeaturesForm Factor and Interface: Most 40G modules use the QSFP (Quad Small Form-Factor Pluggable) or QSFP+ form factor, allowing four independent 10Gbps channels to be combined into a single 40Gbps link. They are hot-swappable and support I2C-based digital diagnostics for real-time monitoring of temperature, voltage, optical power, and bias current . Standards Compliance: 40G modules comply with IEEE 802.3ba/bm standards and QSFP Multisource Agreement (MSA), ensuring interoperability across vendors and network devices . They support multiple protocols, including Ethernet, Fibre Channel, InfiniBand, and SONET/SDH. Fiber Types and Reach:Short-Range (SR4): Uses multimode fiber (MMF) with 850nm VCSEL lasers, ideal for intra-data center links. Standard reach is 100–150 meters, with extended versions up to 400 meters on OM3/OM4/OM5 fibers .Long-Range (LR4/ER4): Uses single-mode fiber (SMF) with 1310nm or 1550nm DFB lasers. LR4 modules typically reach 10 km, while ER4 modules can extend up to 40 km, suitable for metro or regional networks .CSR Modules: Duplex LC connectors for multimode fiber, supporting intermediate distances of 300–440 meters . Connectivity Options: Modules support parallel fiber links with MPO/MTP connectors or duplex LC connections. Some modules allow 4x10G breakout for connecting to multiple 10G interfaces . Power and Efficiency: Power consumption varies by type, typically ≤1.4–3.5W, making them energy-efficient for high-density deployments .ApplicationsData Centers: High-density uplinks, top-of-rack (ToR) switches, and spine-leaf architectures.Enterprise Networks: Core and distribution layer connectivity.Service Providers: Metro and regional 40G links, 5G transport networks, and disaster recovery interconnects.Monitoring: Specialized QSFP BiDi modules allow passive monitoring without interfering with live links .Selection ConsiderationsWhen choosing a 40G optical module, consider:Distance requirements (short, medium, long)Fiber type (single-mode vs multimode)Connector type (MPO/MTP vs LC)Power budget and thermal constraintsVendor compatibility and standards complianceBreakout capability if connecting to multiple 10G ports 40G optical modules are essential for bridging 10G infrastructure to evolving 100G/400G networks, providing high throughput, compact form factor, and cost-effective deployment in modern high-performance networks .
