Common working modes of 10GE optical transceivers

13

The common working mode of the 10GE optical transceiver is subject to the transmission media. For example, M and N in 10GBASE-(M)(N) indicate the corresponding transmission media. The common situation is as follows:
M indicates:
-S: short wavelength (850 nm, multi-mode)
-L: long wavelength (1310 nm, most being single-mode and a few being multi-mode)
-E: extended wavelength (1550 nm, single-mode)
-T: twisted pair
-C: coaxial cable (copper)
-K: backplane
N indicates:
-X: 8B/10B coding
-R: 64B/66B coding
-W: STS-192 encapsulation 64B/66B coding (SONET) parameter 2
-M indicates multi-mode in -LRM. The digit attached to the end indicates the number of lanes, such as CX4 and -LX4.
In summary, common 10GE optical transceivers on the firewall usually use SR (working with a wavelength of 850 nm, multi-mode, and 64B/66B coding) and LR.

Optical transceiver optical fiber types applicable to optical interfaces of the USG2000&5000
Huawei optical interface modules are recommended. The optical interface modules of other vendors may cause device faults due to incompatibility. You need to select the local optical interface module according to the type of the peer optical interface module, considering the rate and single-mode or multi-mode. If the types of optical interface modules at two ends are inconsistent, communications may fail.

Can 10GE optical interfaces of a switch work upon a unidirectional fiber connection
10GE optical interfaces of a switch cannot work upon a unidirectional fiber connection. A unidirectional fiber connection occurs between two 10GE optical interfaces when one interface is Down because the Rx fiber is removed, while the other interface is still Up because its Rx fiber can receive link_Up signals from the PHY layer. A switch determines the status of a 10GE optical interface according to the IEEE 802.3ae standard. As defined in this standard, the MAC layer of a 10GE optical can send local_fault and remote_fault signals. A switch can determine the link status based on only the link status of the PHY layer or based on the link status of the PHY layer and the local_fault and remote_fault signals from the MAC layer. On a Huawei switch, link status of a 10GE optical interface turns Up only when the link status of the PHY layer is Up and both the local_fault and remote_fault signals are 0. When two 10GE optical interfaces are interconnected and the Rx fiber on one interface is removed, this interface goes Down and the MAC layer of the interface generates a local_fault signal. Meanwhile, the local interface sends a fault signal to the remote interface through the Tx fiber. The remote interface receives the link_Up signal from the PHY layer and the remote_fault signal from the MAC layer. Therefore, the link status of the remote interface goes Down.
