100G QSFP28 Transceiver Module MTP/MPO Multimode - Reliable 100G SR4

In this review of the 100G QSFP28 Transceiver Module MTP/MPO Multimode, the bottom line is simple: this module is aimed at network engineers and IT teams who need a cost-effective, standards-compliant 100GBASE-SR4 solution for short-reach data center links. The reviewer found it delivers predictable 100Gb/s performance with the convenience of a hot-pluggable QSFP28 form factor and built-in diagnostics. For anyone replacing or expanding 100G QSFP28 ports on compatible Dell networking gear or other MSA-compliant systems, the module is a practical choice based on reliability and tested interoperability.

Key Features

• Compatibility: Works with Dell QSFP28-100G-SR4 compatible ports and other MSA-compliant hardware for straightforward replacement or upgrades.
• 100G Performance: Supports 100Gb/s data rate using MPO/MTP connectivity to handle high-throughput server and switch links in a data center.
• Multimode Optics: Uses 850nm optics with reach up to 70 m on OM3 and 100 m on OM4, covering typical rack-to-rack and row cabling in enterprise closets.
• Hot-pluggable: The module is plug-and-play and hot-swappable, so it can be installed or replaced without downtime on live equipment.
• DDM Monitoring: Digital diagnostic monitoring provides real-time Tx/Rx and temperature information to help spot potential link issues quickly.
• Tested Quality: Each unit is individually tested on switches before shipment and backed by a 3-year warranty and lifetime technical support.

Who It's For

This transceiver is aimed at system administrators, data center technicians, and network integrators who run 100G Ethernet links and need a reliable, interoperable QSFP28 SR4 optic for short-reach multimode fiber. It is particularly useful when upgrading aggregation or spine links where OM3/OM4 fiber is already in place.

Those who should look elsewhere include teams needing single-mode long-haul optics or specialized features not listed here, such as extended temperature ranges below 0C or nonstandard wavelengths. For hardware that is not MSA-compliant or devices that lack QSFP28 ports, a different transceiver family is required.

Pros & Cons

Pros

• MSA-compliant design ensures broad interoperability with Dell-compatible and other standard QSFP28 ports.
• Supports 100Gb/s over MPO/MTP multimode fiber with useful reach on OM3 and OM4 cabling.
• DDM support and pre-shipment switch testing provide practical operational visibility and confidence.
• Hot-pluggable form factor simplifies maintenance and field replacement in live racks.

Cons

• Limited to multimode short-reach use; not suitable for single-mode or long-distance links beyond the specified OM4 range.
• Operating temperature range starts at 0C, so it may not be ideal for extreme cold environments without climate control.
