Full Compatibility List and Supported Devices of Fiber Optic Transceiver
One of the biggest advantages of third-party optical transceiver is their strong brand compatibility,which helps enterprises cut hardware costs without sacrificing performance.Our 1G SFP 120km optical transceivers are fully tested and certified to work seamlessly with the Huawei VRP (Versatile Routing Platform) systems across switches, routers, and firewalls.
Main Application Scenarios of Fiber Connection Module
Long-Distance Enterprise WAN Links: Directly connecting distant enterprise headquarters, regional data rooms, and remote branch campuses across cities without deploying expensive repeaters.
Carrier & ISP Backbone Aggregation: Providing telecommunication service providers with resilient, long-haul 1G backhaul transport rings for remote subscriber broadband terminals.
Network Security & Firewalls Border Routing: Equipping perimeter security gateways or core enterprise firewall appliances with ultra-long-reach single-mode fiber trunk connections.
Smart City & Industrial Video Surveillance: Transferring raw high-definition traffic monitoring or public utility sensor data back to a centralized control office over continuous 100km spans.



Q1: Does this optical transceiver support Fast Ethernet (100Mbps) speeds? A1: No, it is a dedicated 1.25Gbps transceiver built for line-rate Gigabit Ethernet and Fibre Channel speeds.
Q2: What is the exact operating wavelength of this huawei compatible transceiver? A2: It transmits and receives at a center wavelength of 1550nm.
Q3: Can this transceiver be hot-swapped while the Huawei switch is powered on? A3: Yes, it supports hot-plugging. You can freely install or pull it from an active port slot without disturbing the device.
Q4: What is the total optical link budget for this 120km transceiver? A4: The worst-case optical link budget is approximately 32dB to 33dB (calculated using a minimum 0dBm Tx power and -32dBm Rx sensitivity).
Q5: What is the average power consumption of this module? A5: It features an eco-friendly architecture, consuming a typical average power of only 0.9 Watts (always less than 1.5W).
Q6: Is this optical module compatible with Huawei USG series enterprise firewalls? A6: Yes, it is fully tested and widely used on the SFP interface slots of USG6600 and USG6700 series security firewalls.
