25Gb SFP28 DWDM 15km Transceiver


Hilink SFP28 transceiver is designed for use in 25-Gigabit Ethernet links up to 15km over single-mode fiber. The module consists of DWDM EML Laser, APD in a high-integrated optical sub-assembly. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472. This module is designed for single-mode fiber and operates at a nominal wavelength of 100GHz ITU Grid, C Band DWDM wavelength.

Product description


The module optical connection is duplex LC and shall be compatible with SFP+ 28Gbps and backward compatible with legacy 10G SFP+ pluggable. The SFP28 DWDM LR module is a dual-directional device with a transmitter and receiver plus a control management interface (2-wire interface) in the same physical package. A 2-wire interface is used for serial ID, digital diagnostics and module control function.

An SFP28 (Small Form-Factor Pluggable 28) transceiver is a type of transceiver that is used for transmitting and receiving data over fiber optic cables. It is a compact and high-density module that is used in a variety of networking and communication applications.

A 25G SFP28 transceiver is capable of transmitting data at a rate of 25 Gbps (gigabits per second). It is typically used in high-speed networking applications, such as data centers and backbone networks.

DWDM (Dense Wavelength Division Multiplexing) is a technique used in fiber optic communication systems to multiplex multiple wavelengths of light onto a single fiber optic cable. This allows a large amount of data to be transmitted over long distances without the need for multiple cables.

The distance rating of a transceiver, such as "15km," refers to the maximum distance that the transceiver is able to transmit data over a fiber optic cable. In this case, a 25G SFP28 DWDM transceiver with a distance rating of 15km is capable of transmitting data over a distance of up to 15 kilometers (approximately 9 miles).

The 25G SFP28 DWDM transceivers are an important component of modern networking and communication systems, as they allow for the transmission of high-speed data over long distances using fiber optic cables.
