25G Fronthaul CWDM SFP28 15km Transceiver: CWDM-25GFH-SFP28-15

Our EDGEOPTIC CWDM-25GFH-SFP28-15 is a multi-vendor compatible 25G Fronthaul CWDM SFP28 dual-fiber optical module designed for wavelength-division multiplexed mobile fronthaul applications in 5G and LTE network deployments. Supporting 14 CWDM channels across the 1270-1610nm wavelength range, this transceiver enables high-capacity fronthaul connectivity over shared fiber infrastructure, dramatically increasing network bandwidth utilization.

The CWDM-25GFH-SFP28-15 module transmits on selectable CWDM wavelengths from 1270nm to 1610nm with 14 available channels and receives across the full 1270-1610nm CWDM range supporting up to 18 channels. The transceiver supports data rates from 8.5 to 28.1 Gbps, enabling compatibility with various CPRI (Common Public Radio Interface) options including CPRI Option 7 at 9.830 Gbps, Option 8 at 10.138 Gbps, Option 9 at 12.165 Gbps, and Option 10 at 24.33 Gbps. Host-based Forward Error Correction support enhances signal integrity across multiplexed fronthaul links.

Our 25G Fronthaul CWDM SFP28 transceiver utilizes DML (Directly Modulated Laser) technology for transmission and PIN photodiode for signal reception. The module ensures a 14 dB guaranteed optical link budget, enabling reliable transmission over 15 kilometers of single-mode fiber when deployed with appropriate CWDM multiplexing equipment. The transmitter operates within a wavelength bandwidth of 20nm per channel with launch power ranging from 0 dBm to 7 dBm. The wideband receiver covers the full CWDM spectrum with sensitivity ranging from -14 dBm to 2 dBm and overload protection at 1 dBm.

The CWDM-25GFH-SFP28-15 compatible 25G Fronthaul CWDM module is a hot-pluggable SFP28 transceiver featuring duplex LC/UPC connectors as the optical interface. The electrical interface conforms to SFF-8431, SFF-8432, and SFP28 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP28 host systems across multiple vendor equipment platforms. Our 25G Fronthaul CWDM SFP28 transceiver can be programmed for compatibility with various network equipment manufacturers supporting wavelength-multiplexed fronthaul infrastructure.

The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time operational parameters including transmitted and received optical power levels, module temperature, bias current, and supply voltage. This diagnostic data is accessible via SFF-8472 compliant EEPROM interface, enabling continuous monitoring of transceiver health in mission-critical multiplexed fronthaul environments. Maximum power consumption is 1.2W.

The transceiver operates within a commercial temperature range of 0 to 70°C, suitable for controlled indoor installations. Standards compliance includes 25GBASE-LR, IEEE 802.3cc, and Class 1 FDA/IEC60825-1 laser safety certification. The module is CE marked and RoHS compliant.

Typical applications include high-capacity 5G fronthaul aggregation, C-RAN architectures requiring multiple wavelength channels over limited fiber pairs, CWDM-based fronthaul networks, and mobile infrastructure deployments where fiber availability constraints demand wavelength multiplexing to maximize bandwidth.

Because our focus is providing top quality service, we perform comprehensive quality checks before delivery of our products. As a result, we conduct optical parameter measurements, connector cleanliness tests, and SFP28 transceiver EEPROM memory data validation tests to ensure reliable operation in your fronthaul network.
