25G DWDM SFP28 15km Premium Transceiver: DWDM-25G-SFP28-15P

Our EDGEOPTIC DWDM-25G-SFP28-15P is a multi-vendor compatible high-performance 25G DWDM SFP28 dual-fiber optical module designed for dense wavelength division multiplexed 25 Gigabit Ethernet applications operating over single-mode fiber cabling. The DWDM-25G-SFP28-15P 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 high-performance 25G DWDM SFP28 transceiver utilizes EML (Electro-absorption Modulated Laser) technology for transmission and APD (Avalanche Photodiode) for receiving, delivering superior optical performance for metropolitan and regional DWDM network deployments.

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 DWDM networks with higher insertion losses, multiple OADM nodes, or 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 high-performance architecture enables reliable operation in complex DWDM systems where standard transceivers may struggle.

DWDM-25G-SFP28-15P compatible 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 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 transceiver operational parameters critical for high-performance DWDM channel management.

The module operates within a 0 to 70°C temperature range with maximum power consumption of 2W, optimized for deployment in controlled environment data centers and telecom facilities. The EML laser technology provides exceptional wavelength stability with output power from 0 to 5 dBm and enhanced extinction ratio of 6 dB minimum, ensuring superior signal quality in dense DWDM systems. The APD photodiode receiver delivers outstanding sensitivity of -19 dBm with precise ITU-T DWDM Grid 100 GHz C-Band reception capability, providing 5 dB better sensitivity than standard transceivers. This enhanced receiver performance combined with robust transmit power creates the exceptional 19 dB link budget. The receiver overload protection at -7 dBm ensures safe operation while supporting both 50 GHz and 100 GHz channel spacing. The transceiver achieves multi-vendor interoperability through adherence to industry standards, though equipment with vendor-specific module validation may require custom EEPROM programming for compatibility.

Our 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 metro core DWDM networks with multiple ROADM nodes, data center interconnects with high connector losses, service provider networks requiring extra margin for maintenance, and carrier-grade transport systems with stringent reliability requirements. The enhanced 19 dB link budget provides crucial operational margin for network aging, connector contamination, and unexpected losses 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 rigorous quality checks before delivery including optical parameter measurements, enhanced receiver sensitivity validation, wavelength accuracy verification to ITU grid specifications, connector cleanliness tests, and SFP28 transceiver EEPROM memory data validation tests, ensuring superior performance at the specified DWDM wavelength.
