100G ZR High Power Coherent QSFP28 DCO Ind. Transceiver: 100G-Q28-DCO-ZRHPI

Our EDGEOPTIC 100G-Q28-DCO-ZRHPI is a multi-vendor compatible 100G ZR High Power Digital Coherent Optics (DCO) QSFP28 industrial-grade transceiver module designed for ultra-long-haul 100 Gigabit Ethernet and OTN applications operating over single-mode fiber infrastructure in challenging environmental conditions. This quad small form-factor pluggable transceiver utilizes advanced coherent detection technology with DP-QPSK (Dual Polarization Quadrature Phase Shift Keying) modulation and enhanced transmit power, delivering 103.125 Gbps throughput for the most demanding metro, regional, and long-haul network deployments requiring extended temperature operation.

The 100G-Q28-DCO-ZRHPI module operates using tunable C-Band DWDM technology supporting ITU-T grid channels 13 through 61 (49 channels) with selectable 50GHz or 100GHz spacing. Our 100G ZR High Power Coherent QSFP28 industrial transceiver utilizes ITLA (Integrable Tunable Laser Assembly) for transmission and ICR (Integrated Coherent Receiver) for receiving. The high power variant features enhanced transmit power of 0 to +4 dBm compared to standard ZR modules, enabling extended unamplified reach. On the transmission side, the module converts 4x 25.78125 GBd NRZ electrical input channels into a single coherent optical signal for long-reach fiber transmission.

The transceiver achieves transmission distances up to 100 kilometers over unamplified single-mode fiber, or up to 300 kilometers when deployed with optical amplification infrastructure. The enhanced transmit power provides approximately 8 dB additional link budget compared to standard ZR modules, extending unamplified reach by 20 kilometers. However, distance is just an indicative parameter calculated for comfort of identification – eventually we calculate distance taking into account minimal optical budget, amplifier configuration, and dispersion characteristics of the optical cabling infrastructure.

100G-Q28-DCO-ZRHPI compatible 100G ZR High Power Coherent industrial module is a hot-pluggable QSFP28 with dual LC/UPC connectors as the optical interface. The electrical interface conforms to IEEE 802.3 CAUI-4 specification, ensuring compatibility with standard QSFP28 host systems supporting multiple vendor equipment platforms. Our 100G ZR High Power Coherent 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, supply voltage, and current wavelength channel. The module features Built-in Staircase FEC (Forward Error Correction) integrated within the DSP, which is essential for coherent transmission to detect and correct bit errors across extended transmission paths. The module operates within an extended industrial temperature range of -45°C to +85°C with maximum power consumption of 6W, enabling deployment in outdoor enclosures, remote sites, and environments with significant temperature variations.

Standards compliance includes IEEE 802.3-2022 100GBASE-ZR and ITU-T G.709.2 specifications. The transceiver supports multi-protocol operation including 100G Ethernet (103.125 Gbps) and OTU4 (112 Gbps) for optical transport networks. The tunable C-Band wavelength capability enables flexible channel assignment and seamless integration with existing DWDM transport infrastructure. Our 100G ZR High Power Coherent QSFP28 industrial transceiver is CE/RoHS certified.

Typical applications include outdoor extended-reach deployments without optical amplification, remote site connectivity for oil and gas infrastructure, utility and smart grid backbone networks requiring maximum unamplified distance, transportation and railway communications, and any environment where extended temperature operation combined with high power coherent long-reach capability is required.

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.
