25G Fronthaul LWDM SFP28 10km Transceiver: LWDM-25GFH-SFP28-10I

Our EDGEOPTIC LWDM-25GFH-SFP28-10I is a multi-vendor compatible 25G Fronthaul LWDM SFP28 dual-fiber optical module designed for LAN wavelength-division multiplexed mobile fronthaul applications in 5G and LTE network deployments. Supporting 12 LWDM channels in the 1260-1360nm wavelength range, this transceiver enables cost-effective high-capacity fronthaul connectivity using DML-based technology while maintaining compatibility with standard single-mode fiber infrastructure.

The LWDM-25GFH-SFP28-10I module transmits on selectable LWDM wavelengths across channels 269-318 and receives across the 1260-1360nm LWDM grid. The transceiver supports data rates from 9.83 to 25.78 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. The compliance with CPRI-3/5/7 standards ensures reliable operation in established fronthaul environments. Host-based Forward Error Correction support enhances signal integrity across multiplexed fronthaul links.

Our 25G Fronthaul LWDM SFP28 transceiver utilizes DML (Directly Modulated Laser) technology for transmission and PIN photodiode for signal reception. The DML-based approach provides a cost-effective alternative to EML-based DWDM solutions while maintaining reliable wavelength multiplexing performance within the O-Band spectrum. The module ensures a 15 dB guaranteed optical link budget, enabling reliable transmission over 10 kilometers of single-mode fiber when deployed with appropriate LWDM multiplexing equipment. The transmitter operates within a wavelength bandwidth of 2.1nm (LAN WDM) with launch power ranging from 0 dBm to 6 dBm. The receiver sensitivity ranges from -14 dBm to 2 dBm with overload protection at 2 dBm.

The LWDM-25GFH-SFP28-10I compatible 25G Fronthaul LWDM 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 LWDM SFP28 transceiver can be programmed for compatibility with various network equipment manufacturers supporting LAN 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 2W.

The transceiver operates within a commercial temperature range of 0 to 70°C, suitable for controlled indoor installations. Standards compliance includes 25GBASE-LR and CPRI-3/5/7 specifications. The module is CE marked and RoHS compliant.

Typical applications include cost-optimized 5G fronthaul aggregation, C-RAN architectures requiring moderate wavelength density over limited fiber pairs, LWDM-based metro fronthaul networks, and mobile infrastructure deployments where the balance between channel count and cost-effectiveness favors LAN WDM technology over DWDM alternatives.

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.
