Transceiver modul Lenovo 100GBASE-SR4 QSFP28 TRAN (optické vlákno, 100Gb/s)

Lenovo 100GBASE-SR4 QSFP28 TRAN is a fiber-optic transceiver module engineered for short-range multimode connectivity at aggregated 100 Gb/s. The module follows the 100GBASE-SR4 standard and uses a QSFP28 form factor to deliver high-density, low-latency uplinks and interconnects for data center switches and servers. It is intended for deployment in environments that require compact, high-throughput links on multimode fiber for spine-leaf and top-of-rack architectures.

Advantages

The transceiver provides a compact QSFP28 footprint that supports 100 Gb/s over multimode fiber, enabling increased port density in racks and switches while maintaining compatibility with standard 100GBASE-SR4 optical interfaces. Its design supports short-range multimode links, reduces cabling complexity for aggregated connections, and is suitable for high-bandwidth uplink and switch-to-switch interconnects in enterprise and data center networks.

Suitable for

• Short-range multimode fiber links within data centers
• 100GbE uplinks from servers to switches
• Spine-leaf and top-of-rack switch interconnects
• High-density switch ports requiring QSFP28 modules

Key specifications

• Data rate: 100 Gb/s aggregate
• Standard: 100GBASE-SR4 for short-range multimode fiber
• Form factor: QSFP28
• Optical medium: Multimode fiber (MMF)
• Application: Short-reach links in data centers and enterprise networks

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on a switch or server according to the host device instructions, ensuring the module seats firmly and any retention latch engages. Connect appropriate multimode fiber cables to the transceiver interface, observing correct polarity and connector type. Verify link status and configure the host port as required by the network equipment. Follow equipment vendor guidance for hot-plug insertion and removal to avoid port damage.

Recommendations

Use quality multimode fiber of the appropriate OM specification (as supported by your network design) and keep fiber connectors clean to maintain signal integrity. Match the transceiver with compatible QSFP28 ports and network devices that support 100GBASE-SR4 to ensure proper operation and performance.
