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

Our EDGEOPTIC CWDM-25GFH-SFP28-15I is a multi-vendor compatible 25G Fronthaul CWDM SFP28 dual-fiber optical module engineered for wavelength-division multiplexed mobile fronthaul applications in demanding outdoor and industrial environments. Combining 8 CWDM channel support in the 1470-1610nm wavelength range with an extended operating temperature from -45°C to +85°C and an enhanced 19 dB link budget, this industrial-grade transceiver delivers robust high-capacity fronthaul connectivity in harsh deployment conditions.

The CWDM-25GFH-SFP28-15I module transmits on selectable CWDM wavelengths from 1470nm to 1610nm with 8 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 in challenging thermal environments.

Our 25G Fronthaul CWDM SFP28 industrial transceiver utilizes EML (Electro-absorption Modulated Laser) technology for transmission and PIN photodiode for signal reception. The EML transmitter provides superior signal quality and wavelength stability essential for reliable CWDM operation across extended temperature ranges. The module ensures a 19 dB guaranteed optical link budget, significantly higher than standard variants, enabling reliable transmission over 15 kilometers of single-mode fiber with additional margin for environmental variations. The transmitter operates within a wavelength bandwidth of 20nm per channel with launch power ranging from 0 dBm to 5 dBm. The wideband receiver covers the full CWDM spectrum with sensitivity ranging from -14 dBm to 2 dBm and overload protection at 2 dBm.

The CWDM-25GFH-SFP28-15I 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 industrial-grade 25G Fronthaul CWDM SFP28 transceiver can be programmed for compatibility with various network equipment manufacturers.

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 capability becomes particularly valuable in outdoor industrial deployments where environmental monitoring is essential for proactive maintenance. Maximum power consumption is 1.2W.

The industrial temperature range of -45°C to +85°C makes this transceiver ideal for outdoor cabinet installations, cell tower equipment shelters, and remote aggregation points where wavelength multiplexing is required in extreme climates. 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 outdoor high-capacity 5G fronthaul aggregation, C-RAN deployments in harsh environments requiring wavelength multiplexing, industrial CWDM-based fronthaul networks, and remote cell site connectivity where fiber constraints and temperature extremes demand robust multiplexed solutions.

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 mission-critical fronthaul network.
