10G BiDi SFP+ 20km Transceiver (Tx1330Rx1270): BIDI-10G-SFP-20B

Our EDGEOPTIC BIDI-10G-SFP-20B is a multi-vendor compatible 10G BiDi SFP+ single-fiber optical module engineered for long-reach 10 Gigabit Ethernet applications over single-mode fiber infrastructure using bidirectional transmission technology. The BIDI-10G-SFP-20B module operates with asymmetric wavelengths, transmitting at 1330nm and receiving at 1270nm, supporting data rates from 1.25 to 11.32 Gbps across multiple protocol standards and network applications. Our 10G BiDi SFP+ transceiver utilizes DFB (Distributed Feedback) laser technology for transmission and PIN photodiode with WDM (Wavelength Division Multiplexing) filter for signal reception on the same fiber strand. The transceiver ensures a 9 dB guaranteed optical link budget, which determines the maximum transmission distance capabilities. Over single-mode fiber (SMF), the transceiver can reach distances up to 20 kilometers under optimal conditions. 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.

BIDI-10G-SFP-20B compatible 10G BiDi module is a hot-pluggable SFP+ transceiver with simplex LC/UPC connector as the optical interface, utilizing a single fiber strand for both transmit and receive functions. 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 BiDi SFP+ transceiver can be encoded to be compatible and successfully operate in different 80+ brands of network equipment. 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. The module operates within a 0 to 70°C temperature range, with appropriate thermal considerations for sustained operation in controlled server room environments.

CRITICAL NOTE: BiDi transceivers must be deployed in matched pairs with complementary wavelength configurations. This module (Tx1330/Rx1270) must be paired with the corresponding BIDI-10G-SFP-20A module operating at Tx1270/Rx1330 to establish proper bidirectional communication on a single fiber strand.

Standards compliance includes IEEE 802.3ae for 10 Gigabit Ethernet, along with SDH/SONET specifications and BiDi MSA requirements. 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 compatibility. Our 10G SFP+ BiDi transceiver is CE/RoHS certified, and it is compliant with product safety standards.

Typical applications are metropolitan area network deployments, campus backbone connections with limited fiber availability, intermediate-distance point-to-point links, fiber-to-the-business implementations, and service provider access networks where fiber strand conservation reduces infrastructure costs by approximately 50 percent while extending reach beyond short-range solutions. The multi-rate capability accommodates legacy Gigabit Ethernet operation at 1.25 Gbps alongside native 10 Gigabit rates, providing operational flexibility for mixed-speed network deployments. 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+ transceiver EEPROM memory data validation tests.
