Transceptor SFP28 BiDi BlueOptics BO04Q33610D (S1C96A-BO) — LC-Simplex, 25GBASE-BX-D, monomodo, TX1330nm/RX1270nm, 10 km, DDM, 0–70°C

The BlueOptics BO04Q33610D (S1C96A-BO) SFP28 BiDi transceiver is a singlemode LC-simplex optical module designed for 25GBASE-BX-D applications. It transmits at 1330 nm and receives at 1270 nm over a single fiber pair, supports a data rate of 25 Gbit/s and reaches up to 10 km. The module includes Digital Diagnostic Monitoring (DDM) and is rated for operation in ambient temperatures from 0 °C to 70 °C. Its compact SFP28 form factor follows MSA standards and is intended for use where duplex fiber is limited but high-speed connectivity is required.

Advantages

The transceiver provides a high-density, single-fiber solution for 25 Gbit/s links, reducing cabling footprint while maintaining full-duplex optical communication via BiDi (bidirectional) transmission. Built to MSA form-factor compatibility, it is suitable for common network platforms and supports DDM for real-time monitoring of supply voltage, temperature, laser bias current and optical power. The module’s singlemode design and 10 km reach make it suitable for metro and data center interconnects where longer distances are required compared with multimode solutions.

How to use

Install the SFP28 BiDi transceiver into a compatible SFP28 port on your switch, router or media converter according to the device manufacturer’s hot-plug procedures. Use an LC-simplex patch cable or a matching LC-simplex connector on a patch panel to connect the transceiver to the remote BiDi module; note that the remote end must use the complementary wavelengths (TX/RX swapped). Ensure the host device supports 25GBASE-BX-D and, if you intend to use monitoring features, that it supports DDM/DOM access. Verify link status and diagnostics via your network equipment management interface after insertion.

Recommendations

For reliable long-term operation, use the transceiver within the specified temperature range and ensure clean LC connectors to minimize insertion loss. Pair BiDi modules with complementary wavelength devices and use certified singlemode patch cabling for the full 10 km reach. Enable and monitor DDM parameters where supported to assist with troubleshooting and preventive maintenance.
