1000BASE-BX10 SFP Compatible Transceiver (Side A): BIDI-1.25G-SFP-10-AD

Our EDGEOPTIC BIDI-1.25G-SFP-10-AD is a multi-vendor compatible 1000BASE-BX10 bidirectional SFP optical module designed for extended-reach Gigabit Ethernet 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 particularly valuable for metropolitan access networks and campus backbone connections where fiber conservation delivers significant infrastructure savings.

The BIDI-1.25G-SFP-10-AD module operates at 1310nm wavelength for transmission and 1550nm for reception, supporting data rates from 1.063 to 1.25 Gbps. This Side A transceiver must be deployed in matched pairs with its complementary Side B unit (transmitting at 1550nm, receiving at 1310nm) to establish bidirectional communication over a single fiber strand. Our 1000BASE-BX10 SFP transceiver utilizes FP (Fabry-Pérot) laser technology for transmission and PIN photodiode for signal reception. The module ensures a 12 dB guaranteed optical link budget, supporting transmission distances up to 10 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-1.25G-SFP-10-AD 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 1000BASE-BX10 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.

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 for Gigabit applications. 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 IEEE 802.3ah for 1000BASE-BX10 Gigabit Ethernet along with 1G Fiber Channel support at 1.0625 Gbps. 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 1000BASE-BX10 SFP transceiver is CE and RoHS certified, meeting Class 1 FDA and IEC60825-1 laser safety requirements.

Typical applications include metropolitan access networks, enterprise campus backbone connections, inter-building links, and carrier access infrastructure requiring extended reach over single-fiber paths. 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.
