10G Fronthaul BiDi SFP+ 40km Transceiver (Side B): BIDI-10GFH-SFP-40B

Our EDGEOPTIC BIDI-10GFH-SFP-40B is a multi-vendor compatible 10G Fronthaul BiDi SFP+ single-fiber optical module designed for mobile network infrastructure supporting CPRI and OBSAI protocol standards over extended distances. The BIDI-10GFH-SFP-40B module operates using wavelength division multiplexing technology, transmitting at 1330nm and receiving at 1270nm over a single fiber strand. With data rates from 1.228 to 10.138 Gbps, this transceiver provides fiber-efficient long-reach connectivity between baseband units and remote radio heads in 4G LTE and 5G network deployments where fiber pair availability is limited.

Our 10G Fronthaul BiDi 40km SFP+ transceiver utilizes DFB (Distributed Feedback) laser technology for transmission and PIN photodiode for receiving. The module ensures a 14 dB guaranteed optical link budget, which determines the maximum transmission distance. Over single-mode fiber, the transceiver can reach distances up to 40 kilometers while using only one fiber strand instead of the traditional two-fiber approach. However, distance is just an indicative parameter calculated for comfort of identification – eventually we calculate distance taking into account minimal optical budget and average attenuation of optical cabling in industry.

The BIDI-10GFH-SFP-40B must be deployed in pairs with its complementary module BIDI-10GFH-SFP-40A at the opposite end of the link. The Side B module transmits at 1330nm and receives at 1270nm, while Side A transmits at 1270nm and receives at 1330nm, enabling full-duplex communication over a single fiber. This configuration effectively doubles fiber utilization in fronthaul networks spanning regional distances.

The BIDI-10GFH-SFP-40B supports comprehensive fronthaul protocol coverage including CPRI options 2 through 8, ranging from 1228.8 Mbps to 10.138 Gbps. Additionally, the module supports OBSAI RP3 configurations at 1.536 Gbps, 3.072 Gbps, and 6.144 Gbps rates. This multi-rate capability ensures compatibility with diverse radio access network architectures and equipment generations from major RAN vendors worldwide.

The BIDI-10GFH-SFP-40B compatible 10G Fronthaul BiDi module is a hot-pluggable SFP+ with a single LC/UPC connector as an optical interface. The electrical interface conforms to SFF-8431 MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP+ host systems supporting multiple vendor equipment platforms. Our 10G Fronthaul BiDi 40km SFP+ transceiver can be encoded to be compatible and successfully operate in different baseband unit and remote radio head platforms across the telecommunications industry.

The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time information including transmitted and received optical power levels, module temperature, bias current, and supply voltage. This diagnostic data is available via MSA-compatible EEPROM interface and enables monitoring of transceiver operational parameters critical for extended-distance link management. The module operates within a 0 to 70°C temperature range, with appropriate thermal considerations for sustained operation in controlled equipment room environments.

Standards compliance includes SFF-8431 for mechanical and electrical specifications, along with Class 1 FDA and IEC60825-1 laser safety requirements. Our 10G Fronthaul BiDi 40km SFP+ transceiver is CE/RoHS certified and compliant with product safety standards.

Typical applications include fiber-constrained C-RAN fronthaul connections over regional distances, deployments requiring long-reach single-fiber transmission, and scenarios where fiber scarcity demands maximum utilization of existing infrastructure. Because our focus is providing top quality service, we perform serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanness tests, and SFP+ transceiver EEPROM memory data validation tests.
