25G DWDM SFP28 15km Industrial Premium Transceiver: DWDM-25G-SFP28-15PI

Our EDGEOPTIC DWDM-25G-SFP28-15PI is a multi-vendor compatible industrial-grade high-performance 25G DWDM SFP28 dual-fiber optical module designed for dense wavelength division multiplexed 25 Gigabit Ethernet applications in harsh environmental conditions. The DWDM-25G-SFP28-15PI module supports fixed-wavelength transmission across 40 channels (21-61) in the DWDM C-Band 100 GHz ITU grid, with data rates from 8.5 to 28.1 Gbps supporting multiple protocol standards and applications. Our industrial high-performance 25G DWDM SFP28 transceiver utilizes EML (Electro-absorption Modulated Laser) technology for transmission and APD (Avalanche Photodiode) for receiving, engineered specifically for superior optical performance in extreme temperature environments.

The transceiver ensures an exceptional 19 dB guaranteed optical link budget with host-based Forward Error Correction (FEC) support, which determines the maximum transmission distance capabilities. Over standard single-mode fiber (SMF), the module achieves reliable transmission up to 15 kilometers with significantly enhanced margin compared to standard transceivers, making it ideal for outdoor DWDM networks with higher insertion losses, industrial optical systems with multiple nodes, or harsh environment applications requiring additional optical budget reserve. However, distance is just an indicative parameter calculated for convenience of identification – eventually we calculate distance taking into account minimal optical budget and average attenuation of optical cabling in industry standards. The robust high-performance architecture maintains exceptional link margin across extreme temperature variations.

DWDM-25G-SFP28-15PI compatible industrial high-performance wavelength-specific module is hot-pluggable SFP28 with duplex LC/UPC connectors as an optical interface. The electrical interface conforms to SFF-8431, SFF-8472, IEEE 802.3, SFF-8432, and SFP28 MSA specifications, ensuring compatibility with standard SFP28 host systems supporting multiple vendor equipment platforms. Our industrial high-performance 25G DWDM SFP28 transceiver can be encoded to be compatible and successfully operate in different 80+ brands of equipment. The module incorporates comprehensive 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 EEPROM interface, enabling continuous monitoring of high-performance DWDM channel operation across extreme temperature variations.

The module operates within an extended industrial temperature range of -45°C to +85°C, with maximum power consumption of 2W, specifically designed for deployment in uncontrolled environments including outdoor cabinets, remote cell sites, industrial facilities, and harsh telecom infrastructure. The enhanced thermal design ensures stable EML laser operation with output power from 0 to 5 dBm and maintains the enhanced extinction ratio of 6 dB minimum across all 40 supported DWDM channels even at temperature extremes. The APD photodiode receiver delivers outstanding sensitivity of -19 dBm with precise ITU-T DWDM Grid reception capability, providing 5 dB better sensitivity than standard transceivers while maintaining performance across the industrial temperature range. This enhanced receiver performance combined with robust transmit power creates the exceptional 19 dB link budget critical for harsh environment deployments. The receiver supports both 50 GHz and 100 GHz channel spacing with overload protection at -7 dBm.

Our industrial high-performance 25G DWDM SFP28 transceiver is CE/RoHS certified and compliant with Class 1 FDA and IEC60825-1 laser safety standards. Typical applications include outdoor metro DWDM networks with multiple ROADM nodes, industrial optical transport systems, smart city infrastructure requiring extra margin, railway communications backbone, and utility networks demanding superior performance in extreme conditions. The combination of industrial hardening and enhanced 19 dB link budget provides crucial operational margin for temperature-induced losses, environmental degradation, and unexpected attenuation while maintaining error-free performance. The multi-rate capability accommodates legacy 10 Gigabit Ethernet operation alongside native 25 Gigabit rates, providing operational flexibility for mixed-speed network deployments. Because our focus is providing top quality service, we perform extensive environmental testing including thermal cycling across all DWDM channels, vibration resistance, humidity exposure tests, enhanced receiver sensitivity validation, wavelength stability verification to ITU grid specifications, in addition to optical parameter measurements, connector cleanliness tests, and SFP28 transceiver EEPROM memory data validation tests.
