OC-48 BiDi SFP 80km Transceiver (Side B): BIDI-2.67G-SFP-80-BD

Our EDGEOPTIC BIDI-2.67G-SFP-80-BD is a multi-vendor compatible OC-48/STM-16 bidirectional SFP optical module designed for extended long-reach high-speed SDH/SONET and multi-rate applications operating over single-mode fiber infrastructure. This BiDi transceiver enables cost-effective fiber utilization by transmitting and receiving on a single fiber strand, making it an optimal solution for regional transport networks, long-haul access connections, and scenarios where extended reach combined with fiber conservation delivers substantial infrastructure cost savings while supporting advanced 2.67 Gbps protocol standards.

The BIDI-2.67G-SFP-80-BD module operates at 1550nm wavelength for transmission and 1490nm for reception, supporting multi-rate operation from 100 Mbps to 2.67 Gbps. This exceptional data rate flexibility enables support for legacy 100M Ethernet, Gigabit Ethernet, 1G and 2G Fiber Channel, SDH/SONET standards including STM-1, STM-4, and STM-16, as well as OTN applications including ODU0, ODU1, and OTU1. This Side B transceiver must be deployed in matched pairs with its complementary Side A unit (transmitting at 1490nm, receiving at 1550nm) to establish bidirectional communication over a single fiber strand. The 1550/1490nm wavelength combination is specifically selected for extended distance applications, offering optimal performance characteristics in the low-attenuation window of single-mode fiber. Our OC-48 BiDi SFP transceiver utilizes DFB (Distributed Feedback) laser technology for transmission, providing the superior wavelength stability, narrow spectral width, and high output power essential for reliable extended-reach high-speed operation, paired with PIN photodiode for signal reception. The module ensures a 28 dB guaranteed optical link budget, supporting transmission distances up to 80 kilometers over standard single-mode fiber. However, distance remains an indicative parameter calculated for ease of identification – actual reach depends on minimal optical budget requirements and real-world attenuation characteristics of the installed fiber plant.

The BIDI-2.67G-SFP-80-BD is a hot-pluggable SFP module featuring a single LC/UPC connector as the optical interface. The electrical interface conforms to INF-8074i and SFP MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP host systems across multiple vendor equipment platforms. Our OC-48 BiDi SFP transceiver can be encoded for compatibility with 80+ equipment brands, enabling seamless integration into existing network infrastructure. The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality, providing real-time operational parameters including transmitted and received optical power levels, module temperature, laser bias current, and supply voltage. This diagnostic data is accessible via MSA-compatible EEPROM interface, enabling comprehensive monitoring of transceiver health and performance – particularly valuable for long-distance links where proactive maintenance is critical.

The SFP form factor, while considered a legacy standard, remains widely deployed across enterprise, carrier, and industrial networks due to its proven reliability, broad equipment support, and cost-effectiveness. The multi-rate capability from 100 Mbps to 2.67 Gbps provides exceptional operational flexibility, accommodating legacy protocol migration and mixed-speed network environments within a single transceiver platform. The module operates within a standard 0°C to 70°C commercial temperature range, with appropriate thermal considerations for sustained operation in controlled equipment room environments. Power requirements are met by a single +3.3V supply.

Standards compliance includes Gigabit Ethernet, 1G and 2G Fiber Channel, SDH/SONET OC-48/STM-16 (2.488 Gbps), and OTN OTU1 (2.66 Gbps) support. The transceiver achieves multi-vendor interoperability through adherence to industry MSA standards, though equipment with vendor-specific module validation may require custom EEPROM programming for full compatibility. Our OC-48 BiDi SFP transceiver is CE and RoHS certified, meeting Class 1 FDA and IEC60825-1 laser safety requirements.

Typical applications include regional carrier SDH/SONET transport networks, long-haul OTN aggregation, utility SCADA backbones, railway and transportation communication systems, and long-distance infrastructure requiring single-fiber high-speed connectivity. Because our focus is providing top quality service, we perform rigorous quality checks before delivery. This includes optical parameter measurements, connector cleanliness inspection, and SFP transceiver EEPROM memory data validation tests.
