UnitekFiber supplies multimode 25G SFP28 optical transceiver with a center wavelength of 850nm, and conforms to multiple standards and specifications such as IEEE 802.3, SFF-8472, SFF-8402, SFF-8432, and SFF-8431. Unlike other optical transceivers, the internal transmitter of this optic transceiver is a vertical cavity surface emitting laser (VCSEL), so it is suitable to be used with OM3/OM4 multimode fiber with a fiber diameter of 50/125µm.
The Cisco-compatible SFP28 transceiver provides up to 10 km of 25GBase-BX throughput over single-mode fiber (SMF) using 1330nm-TX/1270nm-RX wavelengths via LC simplex connectors. This bi-directional unit must be used with another transceiver or network equipment of complementary wavelengths. Optical transceiver provides 25GBASE Ethernet connectivity options for 25G Ethernet, telecom and data centers. It is fully compliant with SFF-8472, SFF-8402, SFF-8432, SFF-8431, MSA and eCPRI standards.
Network Connectivity
The electrical interface uses a 20 contact edge type connector. The optical interface uses simplex LC receptacle. This module incorporates Fibertronics proven circuit and DFB technology to provide reliable long life, high performance, and consistent service.
Product Highlights
25G Connectivity for Data Center
SFP28 transceiver provides an efficient solution for 10G-25G-100G network upgrades to meet the continued growth of next-generation data center networks.
Tested in Host Devices for Proven Interoperability
Due to the explosive growth of data center traffic, higher-speed 25G optical modules are required to cope with the huge traffic transmission demand.
The 25G SFP28 optical module adopts high-performance and low-cost DML lasers and utilizes the LAN-WDM optical wavelength, which has become an ideal solution for 5G fronthaul, which can meet various application scenarios of fronthaul. Optical modules can realize passive wavelength division multiplexing and reduce fiber resource consumption.
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.
Good service, products came quickly and were exactly what I needed. Thank you!
