Run the display transceiver slot slot-id verbose command in the system view to check whether the receive power Rx Power of the local interface is within the acceptable range. If so, collect alarms, logs, and configurations, and contact technical support personnel. If not, go to. You can set optical power alarm so that the device generates alarms if the transmit or receive power of an optical module exceeds a threshold. SRM/3/RXPOWER_EXCEEDMINOR: OID Optical module exception, Rx power is too low.

Huawei has model XFP-10G-1550NM-80KM-SM optical module products, which can support 10G Ethernet transmission of 80KM in single-mode fiber, Moduletek Laboratory has tested the sample of this product, which is convenient for you to know more about the product's performance indexes and the effect of. The Huawei eSFP-FE-LH80-SM1550 is a high-performance optical transceiver designed for long-distance data transmission. With its 1550nm wavelength, it supports data rates aligned with STM1 standards over single-mode fiber (SMF) up to 80km. The L-com FXC-SFP-ZX-1G-HWI supports 80KM distance and it is Huawei compliant transceiver. 8 dBm, meaning the network link can handle 3.
