Huawei compatible SFP-25G-SR Description
EdgeOptic’s SFP-25G-SR (OPN 02311KNR) compatible is a Huawei-coded 25GBASE-SR SFP28 version of the EdgeOptic 25G-SFP28-100 multi-vendor 25GBASE-SR SFP28 transceiver. It is a direct replacement for Huawei’s SFP-25G-SR optical module (Huawei ordering part number 02311KNR) and ships with Huawei-recognized EEPROM, so CloudEngine series chassis identify the module as a native Huawei 25GE optic. The OPN 02311KNR is the procurement string used in Huawei price lists and distributor catalogs; SFP-25G-SR is the Huawei product model name.
Optical performance follows IEEE 802.3by Clause 112: 100 m reach on OM4 or OM5 multimode fiber, 70 m on OM3. Transmit power is −5 to +2.4 dBm, receive sensitivity is −10.3 dBm, with a 5.3 dB link budget under host RS-FEC (IEEE 802.3by Clause 108). The module uses an 850 nm VCSEL transmitter, a PIN photodiode receiver, and an LC/UPC duplex connector. DOM telemetry is exposed per SFF-8472. Line rate spans 10.31 to 25.78 Gbps, covering both 10GBASE-SR and 25GBASE-SR host rates. Power draw is 0.3 W maximum over the 0 to 70°C commercial case temperature range.
02311KNR is the Huawei OPN paired with the CloudEngine 25GE switching line: CloudEngine 6800 Series (25GE access and aggregation), CloudEngine 7800 Series (data center core and aggregation), CloudEngine 8800 Series (data center core with 100G/400G uplinks and 25GE server-side ports), and CloudEngine 9800 Series. Huawei’s support documentation for OPN 02311KNR is the authoritative reference for the specific chassis sub-models and VRP software releases that ship with 25G SFP28 support; cross-check against the Huawei support portal before commissioning.
Do not confuse 02311KNR with 02313URP. Both Huawei OPNs appear in some distributor listings under the SFP-25G-SR product name string, but 02313URP is a separate Huawei catalog entry with its own support documentation and a different chassis validation list. Using the wrong OPN in procurement can produce a module that fails the compatibility check at commissioning. 02311KNR is the OPN for this page: the commercial-temperature 25GBASE-SR SFP28 with the short-reach MMF optical envelope. Procurement teams sourcing Huawei 25GE switch optics should reconcile the Huawei price-list OPN against the chassis BOM before order placement.
On CloudEngine chassis, DDM readout surfaces through Huawei VRP interface and transceiver commands where the platform exposes optical telemetry. The telemetry set is the SFF-8472 standard parameter list: transmit power, receive power, laser bias current, module case temperature, and supply voltage. The specific VRP command syntax varies across CloudEngine product generations and VRP releases; refer to the VRP CLI reference for the running chassis release for the exact command path.
Certifications: CE, RoHS, Class 1 FDA, IEC 60825-1. The module is orderable under either the Huawei model name (SFP-25G-SR) or the OPN (02311KNR); EdgeOptic codes the EEPROM to match the Huawei 25GE switching family so the chassis reads the module against its native validation list.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.

Frequently Asked Questions
Which Huawei CloudEngine switches accept the SFP-25G-SR (02311KNR)?
Huawei’s 25GE-capable CloudEngine switching families ship 02311KNR across the line: CloudEngine 6800 Series (25GE access and aggregation), CloudEngine 7800 Series (data center core and aggregation), CloudEngine 8800 Series (data center core with 100G/400G uplinks plus 25GE server-side ports), and CloudEngine 9800 Series. Huawei’s support documentation for OPN 02311KNR carries the definitive sub-model and VRP-release compatibility table and is the authoritative reference for provisioning in production networks.
What is the difference between Huawei OPN 02311KNR and 02313URP?
02311KNR and 02313URP are two distinct Huawei ordering part numbers, each with its own Huawei support page and chassis validation table. 02311KNR is the OPN targeted by this page: the commercial-temperature 25GBASE-SR SFP28 with the short-reach MMF optical envelope. 02313URP is a separate Huawei catalog entry with different specification parameters; refer to Huawei’s dedicated support documentation for 02313URP for its platform scope. Do not substitute one OPN for the other in a Huawei procurement BOM; reconcile the OPN on your Huawei price list against the chassis-specific validation list before order placement.
Does the 02311KNR report DOM through Huawei VRP on CloudEngine switches?
The module implements SFF-8472 DOM (transmit power, receive power, laser bias, case temperature, supply voltage). On CloudEngine chassis the readout is exposed through Huawei VRP interface and transceiver commands where the platform surfaces optical telemetry. The specific command syntax varies across CloudEngine product generations and VRP releases; the VRP CLI reference for the running chassis release documents the exact command path for the optical telemetry view.
Is the EdgeOptic 02311KNR compatible interoperable with genuine Huawei SFP-25G-SR modules on the same switch?
Yes. The module is a 25GBASE-SR short-reach MMF optic per IEEE 802.3by Clause 112 on the optical and electrical interfaces, so fiber-level interoperation with a genuine Huawei SFP-25G-SR at the far end follows the same optical envelope (100 m OM4, 850 nm). EEPROM-level module identity is independent of link-level interop: each module identifies itself separately to the switch it is installed in, and a mixed deployment with EdgeOptic-coded and Huawei-native modules across a link is a supported pattern at the optical and Ethernet layers.
