Direct Sales of LPO Optical Module QSFP28
QSFP28 optical modules, including loopback (LPO) variants, are available for direct purchase from suppliers like Cables on Demand and FS, offering 100G connectivity for data centers and network testing.
QSFP28 Optical Modules
QSFP28 modules support 100 Gigabit Ethernet (100GbE) and are available in multiple types:
- 100GBASE-SR4 (Short-Range Multimode): Uses a 12-lane MTP/MPO fiber interface for distances up to 100 meters over multimode fiber .
- 100GBASE-LR1 (Long-Range Single-Mode): Supports OS1 duplex LC fiber links up to 10 km .
- High-density, low-power options: FS offers modules optimized for data centers, enterprise core networks, and service provider applications . These modules are compatible with standard QSFP28 ports on switches, servers, and host bus adapters, providing plug-and-play installation.
QSFP28 Loopback Modules (LPO)
Loopback modules are specialized testing devices for QSFP28 ports:
- Passive loopback adapters: Plug directly into QSFP28 ports to test connectivity and port functionality without active electronics .
- Configurations: Available with different insertion loss (0–5 dB) and minimal power consumption (0 Watts typical) to simulate network conditions .
- Applications: Ideal for port diagnostics, switch testing, and network validation in lab or production environments.
Purchasing Options
- Cables on Demand: Offers factory-direct QSFP28 and loopback modules with multiple configurations in stock. Contact via [email protected] for direct sales .
- FS (Europe and global): Provides 100G QSFP28 modules with nearby warehouse shipping, 30-day free returns, and support for enterprise and data center deployments .
- Pivotal Optics: Offers a range of optical transceivers including QSFP28 for 1G–400G networks, suitable for direct purchase .
Key Considerations
- Compatibility: Ensure the module matches your switch or server QSFP28 port specifications.
- Distance and fiber type: Choose SR4 for short-range multimode or LR1 for long-range single-mode applications.
- Testing needs: Loopback modules are recommended for port verification and troubleshooting. For direct sales, contacting suppliers via their sales or customer service channels ensures access to factory-direct pricing, stock availability, and technical support.
