Manufacturer's description and specifications:
The Lenovo FRU: 46C3448 and 46C3449 are OEM part numbers for identical 10Gb SFP+ Short Range (SR) Optical Transceiver Modules, originally developed for IBM Blade Network Technologies (BNT) systems, now under Lenovo Networking. These hot-pluggable modules provide high-speed 10 Gigabit Ethernet connectivity over multimode fiber, ideal for data centers, enterprise networks, and short-distance links. They support 10GBASE-SR (10.3125 Gbps) for Ethernet and 10GBASE-SW (9.953 Gbps) for Fibre Channel, with full interoperability across IBM/Lenovo switches, servers, and multi-vendor equipment.
Key highlights:
- 850nm VCSEL laser for reliable short-range multimode fiber transmission
- Up to 300m reach on OM3 fiber – suitable for intra-building or rack-to-rack connections
- Digital Optical Monitoring (DOM) for real-time diagnostics via I2C interface
- Duplex LC connector for easy multimode fiber integration
- Low power consumption (<1.5W) and commercial temperature range for 24/7 operations
Compatibility: IBM/Lenovo RackSwitch (e.g., G8264, EN2092), System x servers, and standards-compliant 10G Ethernet/Fibre Channel gear.
