100GBASE-SR1.2 QSFP28 Transceiver Module | Duplex MMF | LC Connector | DOM Support
Product Overview
The Cisco compatible QSFP-100G-SR1.2 is a high-performance 100GBASE-SR1.2 QSFP28 optical transceiver module designed for short-range 100 Gigabit Ethernet connectivity over duplex multimode fiber (MMF).
Using advanced single-lambda PAM4 modulation technology, the module enables 100G transmission over standard duplex LC multimode fiber infrastructure, simplifying cabling and reducing deployment complexity compared with traditional MPO-based SR4 optics.
The QSFP-100G-SR1.2 supports:
- Up to 60 meters over OM3 multimode fiber
- Up to 100 meters over OM4 multimode fiber
It is optimized for:
- Hyperscale data centers
- Cloud computing infrastructure
- Spine-leaf architectures
- Enterprise core networks
- High-density 100G deployments
- Storage and HPC environments
The duplex LC design allows easier migration from 10G/25G/40G networks to 100G Ethernet while leveraging existing LC multimode cabling infrastructure.
