100GBASE-ZR4+ QSFP28 100km Transceiver: 100G-QSFP28-100P

Our EDGEOPTIC 100G-QSFP28-100P is a multi-vendor compatible 100GBASE-ZR4+ QSFP28 optical module designed for ultra-long-haul 100 Gigabit Ethernet applications operating over single-mode fiber infrastructure. This quad small form-factor pluggable transceiver utilizes four wavelength division multiplexed optical lanes at 25 Gbps each with enhanced optical performance, delivering 103.125 Gbps throughput for the most demanding metro, regional, and long-haul network deployments.

The 100G-QSFP28-100P module operates using LAN WDM technology with four discrete wavelength channels at 1295.56nm, 1300.05nm, 1304.58nm, and 1309.14nm, employing NRZ (Non-Return to Zero) modulation for signal encoding. Our 100GBASE-ZR4+ QSFP28 transceiver utilizes EML (Electro-absorption Modulated Laser) array for transmission and SOA+PIN (Semiconductor Optical Amplifier with PIN photodiode) receiver assembly. This advanced optical architecture incorporates integrated optical amplification to achieve exceptional receiver sensitivity required for ultra-long reach applications beyond standard ZR4 specifications.

Transceiver ensures a 34 dB guaranteed optical link budget with FEC enabled, which determines the maximum transmission distance. Over standard single-mode fiber, the transceiver can reach distances up to 100 kilometers without external amplification. 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 ZR4+ specification represents the highest performance tier within QSFP28 form factor for native 100G NRZ transmission.

100G-QSFP28-100P compatible 100GBASE-ZR4+ module is a hot-pluggable QSFP28 with dual LC/UPC connectors as the optical interface. The electrical interface conforms to SFF-8636 and SFF-8679 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard QSFP28 host systems supporting multiple vendor equipment platforms. Our 100GBASE-ZR4+ QSFP28 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. Additionally, the module supports Host FEC (Forward Error Correction) function which is essential for achieving full 100km reach capability by detecting and correcting bit errors across the extended transmission path. The module operates within a 0 to 70°C temperature range with maximum power consumption of 6.5W, reflecting the additional power requirements of integrated SOA technology.

Standards compliance includes IEEE 802.3ba and IEEE 802.3bm for 100 Gigabit Ethernet, 100GBASE-ZR4+ specification, ITU-T G.959, 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-ZR4+ QSFP28 transceiver is CE/RoHS certified, Class 1 FDA and IEC60825-1 Laser Safety Compliant.

Typical applications include long-haul metro network backbone connections, regional carrier interconnects, submarine cable landing stations, data center interconnects spanning metropolitan areas, and enterprise WAN deployments. The ZR4+ design provides maximum unamplified reach capability within pluggable QSFP28 form factor, extending beyond standard ZR4 specifications.

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.
