EON Technology 40G QSFP+ MPO transceiver modules use four-lane parallel optics over an MTP®/MPO-12 connector for high-density data center interconnect. The family covers 40GBASE-SR4 QSFP+ (150 m OM4), CSR4 (400 m OM4), 40G PSM4 (2 km SMF) and PLR4 (10 km SMF). Compatibility validated by model, firmware, port and optical part number.
Key features
- Connector: MTP®/MPO-12 male — requires a patch cord with a female connector
- Standards: 40GBASE-SR4 · CSR4 · PSM4 · PLR4
- Fiber: MMF OM4 (SR4/CSR4) — SMF G.652 (PSM4/PLR4, up to 10 km)
- Architecture: 4 parallel lanes × 10G = 40G total (40G→4×10G breakout possible)
- DDM/DOM: real-time monitoring of optical power, temperature and voltage
- Hot-pluggable: hot-swap with stable operation under the agreed technical conditions
- MTBF: > 1,000,000 h at 35 °C with a 90% confidence level
- Compliance: MSA — multivendor with Cisco, Juniper, Arista, HPE and other brands; compatibility validated by model, firmware, port and optical part number
