100GBASE-FR1 SFP-DD Transceiver: 100G-SFP-DD-2

Our EDGEOPTIC 100G-SFP-DD-2 is multi-vendor compatible 100GBASE-FR1 SFP-DD dual-fiber optical module designed for 100 Gigabit Ethernet applications operating over single-mode fiber cabling. The 100G-SFP-DD-2 module operates with dual 1310nm wavelengths for transmission and reception, utilizing PAM4 (Pulse Amplitude Modulation 4-level) modulation across two lanes at 53.125 Gbps each to achieve aggregate 106.25 Gbps data rates. Our 100GBASE-FR1 SFP-DD transceiver delivers high-density 100G connectivity optimized for modern data center and campus network architectures.

The transceiver utilizes EML (Electro-absorption Modulated Laser) technology for transmission and PIN photodiode for receiving. This optical configuration ensures a 2.1 dB guaranteed link budget, specifically optimized for short-reach single-mode fiber applications requiring 100G bandwidth. Over standard single-mode fiber, the transceiver reliably achieves 2 kilometers transmission distance, making it suitable for data center interconnects and campus backbone deployments. However, distance is just indicative parameter calculated for comfort of identification – eventually we calculate distance taking in account minimal optical budget and average attenuation of optical cabling in industry.

100G-SFP-DD-2 compatible 100GBASE-FR1 module is hot-pluggable SFP-DD with duplex LC/UPC connectors as an optical interface. The electrical interface conforms to SFP-DD MSA (Multi-Source Agreement) specifications, 100GAUI-2 electrical interface, and 100G Lambda MSA standards, ensuring compatibility with standard SFP-DD host systems supporting multiple vendor equipment platforms. Our 100GBASE-FR1 SFP-DD transceiver can be encoded to be compatible and successfully operate in different 80+ brands of equipment. The module incorporates host-based Forward Error Correction (FEC) support and integrated CDR (Clock and Data Recovery) functionality, essential for maintaining signal integrity in dual-lane PAM4 modulated systems.

The module features comprehensive DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time information including transmitted and received optical power levels for each lane, module temperature, bias current, and supply voltage. This diagnostic data are available via MSA-compatible EEPROM interface conforming to SFF-8472 specifications and enables monitoring of transceiver operational parameters. Operating within a 0 to 70°C temperature range with 3W maximum power consumption, the module maintains efficient thermal performance critical for high-density port configurations in modern switching platforms.

Standards compliance includes IEEE 802.3cu for 100 Gigabit Ethernet, along with SFP-DD MSA and 100G Lambda MSA specifications. The dual-lane architecture utilizing PAM4 modulation enables efficient 100G transmission while maintaining compatibility with evolving data center infrastructure. The compact SFP-DD form factor provides double density compared to traditional QSFP28 modules, enabling higher port density in space-constrained environments. Our 100G SFP-DD FR1 transceiver is CE/RoHS certified and compliant with Class 1 FDA and IEC60825-1 laser safety standards.

Typical applications are leaf-spine data center architectures, high-performance computing clusters, enterprise campus cores, and cloud service provider networks requiring maximum 100G port density. The 100GBASE-FR1 specification provides cost-effective 100G connectivity for reaches up to 2km, bridging the gap between short-reach multimode and longer-reach single-mode solutions. Because our focus is providing top quality service, we are performing serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanness tests and SFP-DD transceiver EEPROM memory data validation tests.
