100GBASE-SR4 QSFP28 Industrial Transceiver: 100G-QSFP28-100I

Our EDGEOPTIC 100G-QSFP28-100I is a multi-vendor compatible 100GBASE-SR4 QSFP28 industrial-grade optical module designed for 100 Gigabit Ethernet applications operating over multimode fiber infrastructure in challenging environmental conditions. This quad small form-factor pluggable transceiver utilizes four parallel optical lanes at 25 Gbps each, delivering aggregate throughput up to 112 Gbps for industrial, outdoor, and harsh environment deployments requiring extended temperature operation.

The 100G-QSFP28-100I module operates at 850nm wavelength across all four transmit and receive channels, employing NRZ (Non-Return to Zero) modulation for signal encoding. Our 100GBASE-SR4 QSFP28 industrial transceiver utilizes VCSEL (Vertical-Cavity Surface-Emitting Laser) array for transmission and PIN photodiode array for receiving. This proven optical architecture delivers reliable performance across the extended industrial temperature range while maintaining cost-effectiveness for short-reach multimode fiber applications.

Transceiver ensures a 1.9 dB guaranteed optical link budget, which determines the maximum transmission distance. Over OM4 multimode fiber, the transceiver can reach distances up to 100 meters, while on OM3 cabling approximately 70 meters. However, distance is just an indicative parameter calculated for comfort of identification – eventually we calculate distance taking into account minimal optical budget and average attenuation of optical cabling in industry. The module requires 8 fibers for full-duplex operation, using four fibers for transmission and four for reception.

100G-QSFP28-100I compatible 100GBASE-SR4 industrial module is a hot-pluggable QSFP28 with MTP/MPO-12 (UPC) connector as the optical interface. The electrical interface conforms to SFF-8636 and SFF-8665 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard QSFP28 host systems supporting multiple vendor equipment platforms. Our 100GBASE-SR4 QSFP28 industrial transceiver can be encoded to be compatible and successfully operate in different 80+ brands of equipment.

The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time information including transmitted and received optical power levels, module temperature, bias current, and supply voltage. This diagnostic data is available via MSA-compatible interface and enables monitoring of transceiver operational parameters. The module operates within an extended industrial temperature range of -40°C to +85°C with maximum power consumption of 3.5W, enabling deployment in outdoor enclosures, industrial facilities, and environments with significant temperature variations.

Standards compliance includes IEEE 802.3bm for 100 Gigabit Ethernet 100GBASE-SR4 specification and QSFP28 MSA. The transceiver achieves multi-vendor interoperability through adherence to industry MSA standards, though equipment with vendor-specific module validation may require custom EEPROM programming for compatibility. Our 100GBASE-SR4 QSFP28 industrial transceiver is CE/RoHS certified, Class 1 FDA and IEC60825-1 Laser Safety Compliant.

Typical applications include industrial automation networks, outdoor cabinet deployments, oil and gas facilities, transportation infrastructure, utility substations, and any environment where standard commercial temperature range is insufficient. The industrial-grade design ensures reliable operation across extreme temperature conditions encountered in these demanding applications.

Because our focus is providing top quality service, we are performing serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanliness tests and QSFP28 transceiver EEPROM memory data validation tests.
