The interface attributes of the 4-port 10GBase LAN/WAN-XFP Integrated Line Processing Unit as below:
| Attributes | Description |
| Connector type | LC/PC |
| Optical interface attributes | Compliant with the selected XFP optical module |
| Working mode | Full-duplex |
| Frame format | Ethernet_II, Ethernet_SAP, and Ethernet_SNAP |
| Network protocol | IP |
Attributes of 10G XFP optical modules:
| Attributes | Description | |||
| Transmission distance | 0.3 km (0.19 mi.) | 10 km (6.21 mi.) | 40 km (24.86 mi.) | 80 km (49.71 mi.) |
| Center wavelength | 850 nm | 1310 nm | 1550 nm | 1550 nm |
| Minimum transmitting power | -7.3 dBm | -6.0 dBm | -1.0 dBm | 0 dBm |
| Maximum transmitting power | -1.3 dBm | -1.0 dBm | 2.0 dBm | 4.0 dBm |
| Receiving sensitivity | -7.5 dBm | -11.0 dBm | -15.0 dBm | -24.0 dBm |
| Overload power | -1.0 dBm | 0.5 dBm | -1.0 dBm | -7.0 dBm |
| Optical fiber type | Multi-mode | Single-mode | Single-mode | Single-mode |
The 10G XFP multi-mode optical transceiver supports two types of multi-mode optical fibers with different cores. Table 4 lists the relationship between the core, the modal/bandwidth, and the transmission distance. During configuration, the length of optical fibers is restricted by the transmission distance. In addition, the optical fiber with the 50 um core and 2000 MHz*km modal/bandwidth is a special type. If this type of optical fiber is required, you need to purchase it additionally.
Transmission distance of 10G XFP optical modules
| Core Fiber (μm) | Modal/Bandwidth (Mhz*km) | Transmission Distance (km) |
| 50 | 2000 | 2~300 (1.24 ~ 186.42) |
| 50 | 500 | 2~82 (1.24 ~ 50.95) |
| 62.5 | 200 | 2~33 (1.24 ~ 20.51) |
In conclusion, as long as the version of main control board supports, the two card can be replaced, and the functions are the same.
