## Summary description

Lenovo 100Gb SR4 QSFP28 transceiver (model 4M27A67042) is a hot‑pluggable optical module for high‑speed data links over multimode fiber. Designed for QSFP28 ports, it supports 100Gb/s SR4 operation for short‑reach connections in data centers and enterprise networks. Use for server uplinks, switch interconnects and aggregation where compact, high‑bandwidth links are required.

## Long description

Lenovo 100Gb SR4 QSFP28 is a hot-pluggable optical transceiver module designed for high-density 100 Gigabit Ethernet connections over multimode fiber. Engineered for QSFP28 ports, this multimode SR4 module delivers short-reach 100Gb/s links suitable for data center topologies, server uplinks and switch interconnects where compact form factor and high bandwidth are required.
Advantages
This transceiver offers a QSFP28 form factor that enables four-lane 25Gb/s electrical interfaces aggregated into a single 100Gb/s optical link, supporting efficient use of switch port density and simplified cabling in rack and spine-leaf architectures. As a hot-pluggable module, it allows in-service insertion and replacement without powering down equipment, reducing maintenance windows. The multimode SR4 design is optimized for short-reach connections, offering low power consumption and predictable optical performance across typical multimode fiber types used in modern data centers.
Suitable for
 Short-reach 100Gb/s uplinks between servers and top-of-rack or leaf switches
 Switch-to-switch aggregation inside data center racks and across adjacent racks
 High-bandwidth connections in enterprise and campus core fabrics
 Environments requiring compact QSFP28 modules for high port density
Key specifications
 Optical interface: Multimode SR4 supporting 100Gb/s aggregated over four 25Gb/s lanes
 Form factor: QSFP28 (hot-pluggable)
 Reach: Short-reach multimode operation suitable for data center links (hundreds of meters on approved multimode fiber)
 Wavelength: Four-lane multimode optical signaling
 Power consumption: Low-power design appropriate for high-density installations
 Connector type: Standard MPO/MTP-style fiber connector for parallel multimode links
How to use
Install the transceiver into a compatible QSFP28 port on a switch or server adapter until it latches, then connect the multimode MPO/MTP fiber cable that matches the data center polarity and fiber type. Ensure that the link partners support 100Gb SR4 multimode operation and verify link status via the host device management interface. For removal, follow hot-swap procedures: disable the port if required by policy, depress the module latch and extract the transceiver carefully to avoid damage to the optical interface.
Usage recommendations
Use verified multimode fiber and MPO/MTP patching assemblies that comply with data center standards to achieve expected reach and signal integrity. Confirm compatibility with the host equipment's transceiver compatibility matrix and perform optical cleaning and inspection of connectors before insertion to prevent performance degradation.
