UnitekFiber provides 25G SFP28 optical transceiver, which is a low cost and low power consumption optical transceiver. 10G optical transceivers cannot meet the current needs of users for the network, so 25G SFP28 has been favored by most people.
This HW DWDM-SFP25G-IR Compatible SFP28 transceiver provides 25GBase-DWDM throughput up to 10km over single mode fiber (SMF) using a wavelength of 1560.61nm via an LC duplex connector. Sfp transceiver provides 25GBASE Ethernet connectivity option for 25G Ethernet, telecom and data center. It is fully compliant with the SFP28 MSA, CPRI and eCPRI standard.

25G Connectivity for Data Center
The 25G DWDM SFP28 optical module is a single-mode duplex with a working wavelength range of 1271~1331nm, which can be used for short-distance data transmission in 25G Ethernet switches, routers, network interface cards (NICs) and storage network equipment.
Tested in Host Devices for Proven Interoperability
The 25G DWDM SFP28 optical module can transmit up to 10km through single-mode fiber. SFP28 optical module can not only increase the bandwidth but also realize long-distance transmission.
As an upgraded version of SFP+, SFP28 can handle 25Gbit/s per channel while ensuring backward compatibility with SFP and SFP+ 25G DWDM SFP28 DOM Optical Transceiver Modules are an important carrier for implementing 25G Ethernet technology in cloud and enterprise data center environments.

25G optical modules are roughly divided into three types, 25G dual-fiber modules, 25G WDM modules, and 25G BIDI modules.
We need to ensure that the receiving power of the module is not more than the receiver overload power to avoid the module being broken. So to get the 25G LR to work at 10m, you need to add about 3dB attenuation.
Yes, Unitekfiber's optical modules are compatible with Fiberhome, Huawei, ZTE, Cisco, Ericsson, Nokia and other brands.
The power consumption of this module <1w.
100G SR4 multi-mode optical modules can be used for interconnection. Under the premise of equipment support, 100G QSFP28 ports can be configured as 4*25G mode, and then MPO-LC fiber jumpers are used to connect 100G SR4 optical modules and 25G SFP28 optical modules.
At present, 25G SFP28 optical modules can transmit up to 40 kilometers. There are 25G SFP28 ER, 25G SFP28 bidi, 25G SFP28 CWDM, and 25G SFP28 DWDM.
Pulling this through ceilings and in conduit - this is fantastic cable. Flexible doesn't hold shape. Very nice to crimp as well.
