The optical interface adopts dual LC sockets with high port density; 25G SFP28 optical transceiver adopts DFB laser and PIN photodetector. Transmitter and receiver have built-in CDR, which is mainly used in 25G Ethernet. SFP28 25G optical module supports the DOM (Digital Optical Monitoring) function, which can help network management to monitor all aspects of the optical transceiver in real time. The multimode SFP28 25 optic modules is widely used, mainly for 25G Short-distance data transmission in Ethernet switches, routers, network interfaces (NIC) and storage network equipment.
SFP-25G-SR-S compatible SFP28 transceiver adopts LC duplex connectors, reaching a link up to 100m over OM4 MMF (70m over OM3). The SFP28 optical module supports running on the same 1G/10G network cabling Infrastructure, giving 2.5 times increase in speed at least, and the built-in DDM/DOM functions monitor the real-time operating status. Each 25G SFP28 CWDM transceiver is individually tested on a series of Cisco switches, and is fully compliant with the SFP28 MSA, RoHS, CPRI, and the eCPRI standards.
Network Connectivity
Product Highlights
25G Connectivity for Data Center
The optical module adopts a hot-swappable SFP28 package, and the transmission distance through single mode fiber can reach up to 10km/15km.
Tested in Host Devices for Proven Interoperability
SFP28 transceiver is an enhanced version of SFP+ and has the same size as SFP+, but SFP 25G optical module can support a single-channel 25Gb/s rate.
SF28 optical transceiver module is individually tested to be used on a series of switches, routers, servers, network interface card etc. Data center switches usually have very dense ports. Low-power optical modules can not only save energy consumption, but also alleviate the problem of excessive heating of optical modules.
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.
Economical, arrived fast, tested out with good numbers after installation. Stripping and polishing was normal.
I am very happy with the cables, price and delivery and will probably continue to buy from UnitekFiber. I'm sure I'll be placing another small order in the next few days.
The ordering process was great, with a speedy delivery. I am due to have the products installed next week and can follow up with further feedback once tested. So far I have been very impressed.
Great product, will purchase more optical transceiver in the near future.
Currently, I am conducting compatibility testing between the 100G transceiver module and my devices, and the UnitekFiber products seem quite impressive. They have started running, and everything is working well. There are no compatibility or performance issues, and the bandwidth and transmission speed have been tested successfully.
