The popularity of high-reliability and low-cost C-band 25G DWDM devices has always restricted the upgrade of long-distance telecom networks based on single-wavelength 25G. Considering the chip resources, device performance, and costs, C-band 25G DWDM devices currently have very few solutions or manufacturers that can supply them in batches. Although the industry provides a relatively low-cost solution that is achieved by overclocking a traditional C-band 10G DWDM EML to 25G, this temporary solution is limited by inherent device performance. There are uncertainties in TOSA performance, yield, and delivery, which greatly limit the large-scale promotion and application of 25G DWDM systems.
In response to this market demand, 3Coptics launched a C-band 25G DWDM SFP28 15km(Industrial Available)optical module recently.

The promotion and application of 25G DWDM SFP28 will have a large positive impact on the communication network. In telecommunications transmission network applications, coherent optical transmission technology is required for applications with a transmission distance greater than 80 kilometers at a 25G rate. However, the cost of coherent optical modules is extremely high currently, while the cost of the 25G DWDM SFP28 solution is much lower. In the case of using multi-wavelength DWDM networking, even considering the costs of fiber amplifiers and dispersion compensation modules, the 25G DWDM SFP28 plus optical amplifier plus dispersion compensation solution still has a huge cost advantage. In addition, in 5G construction, 25G DWDM SFP28 also provides a more efficient low-cost mid-fronthaul solution than LWDM and MWDM.
Since this year, 3Coptics has increased investment in automation construction to ensure product quality and improve product performance consistency. An internal automation team has been set up to transform outsourced equipment according to its own proprietary technology. Related automation equipment is developed to promote the automation process construction of each product line. 3Coptics’s 25G DWDM SFP28 is compatible with the 10G DWDM SFP+ production process, which has achieved automated production of the entire process. The automated route combined with a simple optical module production structure and efficient process flow ensures a very high pass-through rate and yield of the optical module and effectively reduces the cost of the optical module.
The mass production of 3Coptics’s 25G DWDM SFP28 15km optical module provides a high-performance, highly reliable, and predictable low-cost optical module solution for the 5G fronthaul applications and the industry to smoothly upgrade from 10G DWDM optical transmission system to 25G.
3Coptics’s products cover various rates from 100M to 400G and various packaged optical transceivers and cables, including low-speed 100M, 1.25G/2.5G SFP, GPON OLT/ONU, 10G XFP, SFP+, and high-speed 10G optical modules such as XGSPON OLT/ ONU. We also offer 40G QSFP+, 100G QSFP28, CFP, 400G QSFP-DD, and other industry-leading optical modules and direct-connect cable products. We can provide CWDM, DWDM passive wavelength division solutions, OTN transmission solutions, FTTX solutions, 5G fronthaul solutions, and DCI transmission solutions for global customers.
In recent years, 3Coptics has successively developed 25G MWDM QSFP28 for 5G applications and 100G DWDM QSFP28 80km optical modules for DIC transmission applications. The air-tight TOSA used in the 25G DWDM SFP28 15km optical module enables 3Coptics to provide customers with a full set of mass-produced high-performance and high-reliability optoelectronic integrated device solutions at rates from 10G to 400G, further consolidating 3Coptics's dominant position in the optical communication industrial chain.
