Optical Interface FAQ: Transceiver Compatibility Guidelines for Huawei Part Numbers

Overview & Thematic Scope

Deciphering Huawei optical transceiver part numbers is essential for network engineers and procurement specialists to ensure compatibility, performance, and seamless deployment. This FAQ focuses on the optical interface and transceiver compatibility aspects of Huawei part numbers, covering naming conventions, speed and distance interpretation, and verification methods.

Frequently Asked Questions

Q1: What is the general naming convention for Huawei optical transceivers?

Huawei optical transceiver part numbers follow a specific convention that encodes the form factor, data rate, distance type, and wavelength . The general structure is: [Form Factor][Rate][Distance Type][Distance][Module Type][Wavelength]. For example, in ‘OSX010000’, ‘OSX’ indicates the form factor (SFP+), ’01’ denotes the rate (10GE), and ‘0000’ specifies the transmission distance and wavelength details.

Q2: How can I determine the speed and distance capabilities from a Huawei part number?

The speed and distance capabilities are typically encoded in the middle digits of the part number . For instance, in ‘SFP-10G-SR’, ’10G’ indicates a 10 Gigabit speed, and ‘SR’ stands for Short Range, usually up to 300 meters on multimode fiber. Similarly, ‘LR’ means Long Range (up to 10km), and ‘ER’ means Extended Range (up to 40km). Always cross-reference with the official Huawei datasheet for precise specifications.

Q3: What is the difference between Huawei part numbers like ‘OSX010000’ and ‘SFP-10G-SR’?

Both ‘OSX010000’ and ‘SFP-10G-SR’ refer to a 10GBASE-SR SFP+ transceiver, but they represent different coding systems . ‘OSX010000’ is a specific ordering or manufacturing code used internally by Huawei and its partners, while ‘SFP-10G-SR’ is a more descriptive, standards-based naming convention. The ‘Vendor Part Number’ field in a switch’s ‘display interface’ command will often show the ‘OSX’ or ‘023’ style code, while the model is described separately .

Q4: How do I verify if a third-party transceiver is compatible with a Huawei switch?

Huawei switches may generate an alarm for non-Huawei-certified transceivers, though functionality is often unaffected . To verify compatibility, check the switch’s log for a ‘Non-Huawei-certified transceiver’ warning and compare the transceiver’s specifications (speed, wavelength, distance) against the switch’s port capabilities. For guaranteed performance and support, it is recommended to use transceivers with a Huawei part number or those explicitly listed in the switch’s hardware description document.

Q5: Where can I find the serial number and manufacturing details of a Huawei optical module?

The serial number and manufacturing details can be found physically on the label attached to the transceiver . You can also retrieve this information directly from the switch using the CLI command ‘display interface interface-type interface-number transceiver’. The output will display the ‘Manu. Serial Number’ and ‘Manufacturing Date’ .

Q6: How do I interpret the ‘Transceiver Type’ output from a Huawei switch?

The ‘Transceiver Type’ field in the ‘display ap optical-info’ or ‘display interface transceiver’ output shows the standard type of the module, such as ‘1000_BASE_LX_SFP’ or ’10GBASE_SR’ . This provides a clear indication of the module’s standard and speed. The output also includes critical diagnostic information like temperature, voltage, and transmit/receive power levels .

Q7: What does the ‘Digital Diagnostic Monitoring’ (DDM) field indicate?

The ‘Digital Diagnostic Monitoring’ (DDM) field indicates whether the optical module supports real-time monitoring of parameters like temperature, supply voltage, and optical power . If set to ‘YES’, the switch can provide detailed diagnostic information, which is crucial for proactive network maintenance and troubleshooting. Not all modules, like the SFP-1000BaseT copper module, support DDM .

Q8: What are the typical part numbers for Huawei 10G and 40G optical transceivers?

Common 10G SFP+ part numbers include OSX010000 (SR), OSX001002 (LR), and OSX040N01 (ER) . For 40G QSFP+, typical part numbers are QSFP-40G-SR4, QSFP-40G-LR4, and QSFP-40G-FR4, which are used for multimode, single-mode, and extended-reach single-mode applications, respectively . Always confirm the specific part number against the intended switch model and fiber type.
