10G Fronthaul BiDi SFP+ 80km Transceiver (Side B): BIDI-10GFH-SFP-80B

Our EDGEOPTIC BIDI-10GFH-SFP-80B 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 ultra-long distances. The BIDI-10GFH-SFP-80B module operates using wavelength division multiplexing technology, transmitting at 1550nm and receiving at 1490nm over a single fiber strand. With data rates from 1.228 to 10.138 Gbps, this transceiver provides fiber-efficient maximum-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 80km SFP+ transceiver utilizes EML (Electro-absorption Modulated Laser) technology for transmission and APD (Avalanche Photodiode) for receiving. This high-performance optical component combination enables the module to ensure a 23 dB guaranteed optical link budget, which determines the maximum transmission distance. Over single-mode fiber, the transceiver can reach distances up to 80 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-80B must be deployed in pairs with its complementary module BIDI-10GFH-SFP-80A at the opposite end of the link. The Side B module transmits at 1550nm and receives at 1490nm, while Side A transmits at 1490nm and receives at 1550nm, enabling full-duplex communication over a single fiber. This configuration effectively doubles fiber utilization in fronthaul networks spanning extensive geographic distances.

The BIDI-10GFH-SFP-80B 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-80B 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 80km 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 ultra-long-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 80km SFP+ transceiver is CE/RoHS certified and compliant with product safety standards.

Typical applications include fiber-constrained C-RAN fronthaul connections over ultra-long distances, rural deployments with severely limited fiber availability, and scenarios requiring maximum single-fiber transmission reach without optical amplification. 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.
