A 10 Gbps bidirectional SFP+ transceiver using Tx 1330 nm and Rx 1270 nm wavelengths for 60 km single-mode fibre links
This single-mode transceiver delivers 10 Gbps over a simplex LC connection using Tx 1330 nm and Rx 1270 nm wavelengths. It suits network operators extending 10GBASE-BX links to 60 km without intermediate amplification. The module is hot-pluggable and coded for broad switch compatibility. It targets teams that need a drop-in spare for existing BIDI infrastructure.
The unit draws power from a single 3.3 V supply and runs within the commercial temperature range specified by the vendor. A 1330 nm DFB laser and APD receiver keep optical margins stable across the 60 km span. No active cooling is required inside the SFP+ cage. Power draw stays within MSA limits for dense line-card deployments.
The transceiver supports continuous operation from 8.5 Gbps up to 11.32 Gbps covering 10G Ethernet, 8G/10G Fibre Channel, OTN OTU2/OTU2e/OTU2f and CPRI options 7 and 8. Diagnostic monitoring via the 2-wire SFF-8472 interface reports real-time temperature, voltage and optical levels. Link integrity is maintained over the full 60 km without error-rate degradation during prolonged traffic.

Insert the module into an SFP+ cage until it clicks, then attach the simplex LC patch cord straight in — forcing it at an angle cracks the ferrule and ruins the 1330 nm DFB laser alignment.
No scheduled maintenance is required; if bit errors rise, clean the LC end-face with a one-click cleaner and re-check the 2-wire SFF-8472 diagnostic registers for receive-power alarms.
The 60 km SMF reach is the design limit; beyond that the 1330 nm Tx / 1270 nm Rx budget cannot overcome attenuation and dispersion, so errors appear before any thermal throttle.
