The 25G Ethernet technology adopted by 25G optical transceiver is a new Ethernet standard with multiple advantages. It was proposed by the IEEE802.3 working group in July 2014 and was fully revised in June 2016. 25G Ethernet technology can maximize the bandwidth and port density of the data center, and can achieve 100Gb data transmission through the single-channel physical layer technology of 25Gb/s. SFP28 25G optical transceivers are generally used with single-mode patch cord OS2 to be widely used in data center 25G Ethernet and 5G fronthaul CPRI/eCPRI networks, and the maximum transmission distance can reach 10KM.
The Cisco SFP-25G-LR-S Compatible SFP28-SM-25G-31-10K is a single-Channel, Pluggable, Fiber-Optic SFP28 for 25 Gigabit Ethernet and Infiniband EDR Applications. SFP28 transceiver is a high performance module for short-range data communication and interconnect applications which operate at 25.78125 Gbps up to 10km using OS2 fiber. This optical module is designed to operate over singlemode fiber systems using a nominal wavelength of 1310nm.
Network Connectivity
The optical interface uses a duplex LC connector. SFP28 optical modules provide reliable long life, high performance and consistent service. 25G optical modules will become the mainstream solution for 5G fronthaul.
Product Highlights
25G Connectivity for Data Center
DWDM 25G optical transceiver are designed for carrier and large enterprise networks that require scalable, flexible and cost-effective systems.
Tested in Host Devices for Proven Interoperability
Meet the needs of 5G fronthaul services, with a maximum transmission distance of up to 10 kilometers, suitable for 25G Ethernet and CPRI/eCPRI 5G fronthaul networks.
DWDM SFP28 transceiver modules are widely used in telecommunications, cable TV and data centers with large data traffic. With the rapid growth of network traffic, data centers are constantly upgraded and iterated, bringing huge opportunities to the optical module industry. As the core component of long-distance and large-capacity optical networks, fiber optic transceivers are developing towards small size, high speed, and low power consumption in order to meet the market development trend.
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.
Very good service and quality.
The fiber cable was very easy to pull both indoor & outdoor. It's not stiff, went thru conduits nicely.
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.
I have put this transceiver modules into service and they work well. I use them in a personal environment rather than a professional one, but I will probably buy more in the near future.
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.
This module meets my expectations and has been running reliably without any issues so far. And The logistics were fast. Highly recommended.
