Features and Specifications
Utilising WDM technology, FS 10G BiDi SFP+ transceiver features a single fibre port directly on the transceiver itself. This technology employs two distinct wavelengths: one for upstream and one for downstream communication, enabling bidirectional data transmission over a single fibre. FS 10G BiDi SFP+ transceivers are offered in four configurations: 1270nm-TX/1330nm-RX, 1330nm-TX/1270nm-RX, 1490nm-TX/1550nm-RX, and 1550nm-TX/1490nm-RX. Detailed parameters are outlined in the chart below:
| Wavelength | Max. Data Rate | Available Distance | Connector | Optical Components | DOM Support | Protocols |
| 1270nm-TX/1330nm-RX | 10.3125Gbps | 10km, 20km, 40km, 60km | LC simplex | DFB BiDi | Yes | SFP+ MSA Compliant, CPRI, eCPRI |
| 1330nm-TX/1270nm-RX | 10.3125Gbps | 10km, 20km, 40km, 60km | LC simplex | DFB BiDi | Yes | SFP+ MSA Compliant, CPRI, eCPRI |
| 1490nm-TX/1550nm-RX | 10.3125Gbps | 80km, 100km | LC simplex | DFB BiDi | Yes | SFP+ MSA Compliant, CPRI, eCPRI |
| 1550nm-TX/1490nm-RX | 10.3125Gbps | 80km, 100km | LC simplex | DFB BiDi | Yes | SFP+ MSA Compliant, CPRI, eCPRI |
Note: BiDi transceivers must be used in pairs, which means if you use 1270nm-TX/1330nm-RX at one end, the other end of the link must be a 1330nm-TX/1270nm-RX transceiver.

Application
FS BiDi SFP+ transceivers are designed for long-haul 10Gb links. Nowadays, many enterprises and campuses are using BiDi transceivers to replace the legacy duplex SFP+ transceivers. Especially for campus environments requiring fibre connectivity to a large number of endpoints, FS brings the solution. The following figure shows a common 10G link between SFP+ switches via BiDi SFP+ transceivers and an LC simplex cable.
