- High speed I/O electrical interface
- Digital diagnostic monitoring (DDM) via I²C
- QSFP28 MSA compliant form factor with simplex LC receptacle
- Single +3.3V power supply
- Support HW TX_DIS and RX_LOS for telecom application
- Maximum power consumption< 4 W
- Operating case temperature: 0 to +70 °C
- Complies with EU Directive 2015/863/EU
Standard
- 100G single Lambda MSA
- IEEE 802.3bm
- QSFP28 MSA
- SFF-8636
Application
- Interconnection across data centers/between buildings: Suitable for interconnection of campus backbone networks with a distance ranging from 10km to 20km.
- Fiber shortage situation: When the existing single-mode fiber conduits are full and an additional 100G bandwidth needs to be expanded, it is the best alternative to the traditional dual-fiber module.
