Irish manufacturer s pluggable optical module 40G

40G QSFP+ optical modules are compact, hot-pluggable transceivers designed for high-speed Ethernet and fiber channel applications, supporting both short- and long-range transmission.

Key Features

• Form Factor: QSFP+ (Quad Small Form-factor Pluggable Plus), hot-pluggable for easy installation and replacement in switches, routers, and servers .
• Data Rate: Supports 40Gb/s aggregate bandwidth, typically using 4 lanes of 10Gb/s each .
• Transmission Distance: Options range from 100 meters over multimode fiber to up to 90 km over single-mode fiber, depending on the module type (SR, LR, ER, DWDM), .
• Connector Types: MPO/MTP for multimode short-range, LC duplex for single-mode long-range .
• Standards Compliance: IEEE 802.3ba-2018, 40GBASE-SR4/LR4/ER4, and QSFP MSA (SFF-8436) compliant .
• Applications: Data centers, metropolitan area networks, local area networks, 5G fronthaul, high-performance computing, and cloud computing .
• Breakout Capability: Some QSFP+ modules support breakout to four 10G links, enabling flexible network scaling without full 100G upgrades .

Types of 40G QSFP+ Modules

• Short-Range (SR4): Up to 100–150 meters over multimode fiber, ideal for intra-data center connections .
• Long-Range (LR4): Up to 10 km over single-mode fiber, suitable for metro networks .
• Extended Reach (ER4): Up to 40 km over single-mode fiber for regional networks .
• DWDM QSFP+: Supports dense wavelength division multiplexing for long-distance data center interconnects, up to 80 km with dispersion compensation .

Considerations for Selection

• Compatibility: Ensure the module is compatible with your switch or router vendor; many modules support over 100 brands .
• Power and Diagnostics: Typical QSFP+ modules operate at +3.3V, with built-in digital diagnostics for monitoring temperature, voltage, and optical power .
• Cost and Lifecycle: QSFP+ modules remain relevant for networks that require 40G connectivity without upgrading to 100G, offering cost-effective scaling . While the web results do not identify a specific Irish manufacturer, companies like Smartoptics and C-LIGHT provide 40G QSFP+ modules with broad compatibility and multiple transmission options . For sourcing from Ireland, it may be necessary to contact local distributors or network equipment suppliers to confirm availability.
