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

Our EDGEOPTIC CWDM-25G-SFP28-15PI is a multi-vendor compatible industrial-grade high-performance 25G CWDM SFP28 dual-fiber optical module designed for wavelength division multiplexed 25 Gigabit Ethernet applications in harsh environmental conditions. The CWDM-25G-SFP28-15PI module supports transmission across 8 CWDM channels from 1470nm to 1610nm with 20nm channel spacing, with data rates from 8.5 to 28.1 Gbps supporting multiple protocol standards and applications. Our industrial high-performance 25G CWDM 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 CWDM 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.

CWDM-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-8432, and SFF-8472 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP28 host systems supporting multiple vendor equipment platforms. Our industrial high-performance 25G CWDM 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 CWDM 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 1.2W, specifically designed for deployment in uncontrolled environments including outdoor cabinets, remote cell sites, industrial facilities, and transportation infrastructure. The enhanced thermal design ensures stable EML laser operation with output power from 0 to 7 dBm and maintains the 3.5 dB minimum extinction ratio across all 8 supported CWDM channels (1470nm-1610nm) even at temperature extremes. The APD photodiode receiver delivers outstanding sensitivity of -19 dBm with wide-band reception capability spanning the entire CWDM grid from 1270nm to 1610nm, providing 5 dB better sensitivity than standard PIN-based receivers 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 overload protection at -7 dBm ensures safe operation.

Our industrial high-performance 25G CWDM SFP28 transceiver is CE/RoHS certified and compliant with Class 1 FDA and IEC60825-1 laser safety standards. Typical applications include outdoor metro CWDM networks with multiple add-drop 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 CWDM capability enables operators to deploy up to 8 independent 25G channels over existing fiber infrastructure, providing 200 Gbps aggregate capacity with exceptional reliability. 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 CWDM channels, vibration resistance, humidity exposure tests, enhanced APD sensitivity validation, wavelength accuracy verification, in addition to optical parameter measurements, connector cleanliness tests, and SFP28 transceiver EEPROM memory data validation tests.
