Product Description
The Lantronix TN-SFP-xx25G-xR-S Series 25G SFP28 transceiver modules are designed to install in any SFP28
port allowing for 25G/10GBase-X interfaces to the network via the SFP28 connector. The TN-SFP-xx25G-xR-S
transceivers are Cisco Compliant and are designed for bi-directional serial-optical data communication such as
25G Ethernet at speeds up to 26.5 Gbps.
Lantronix SFP28 modules fully comply with the Multi-Sourcing Agreement (MSA). This compliance allows our
SFP28 modules to be used in all other MSA compliant SFP28 platforms. In addition, Lantronix SFP28 modules
are also Compliant with all Cisco SFP28 based routers and switches, as well as Cisco’s IOS software.
Lantronix SFP28 modules are not Cisco OEM brand modules.
These SFPs are intended for 25G Ethernet and eCPRI for 5G Fronthaul/Backhaul applications. The eCPRI
Interface Specification for the Common Public Radio Interface is an industry cooperation aimed at defining
publicly available specifications for the key internal interface of radio base stations, such as eCPRI connecting the
eCPRI Radio Equipment Control (eREC) and the eCPRI Radio Equipment (eRE) via a “fronthaul transport
network”. See the latest eCPRI specification at http://www.cpri.info/downloads/eCPRI_v_1_1_2018_01_10.pdf .
RRH (Remote Radio Head) are distributed on the towers every few miles in cities and suburban areas. These
RRHs must be connected to baseband units sitting at centralized locations. The connection between the RRUs
and the base station is often called “fronthaul.” While 4G (LTE) uses CPRI (Common Public Radio Interface) as
the fronthaul connection, eCPRI (enhanced CPRI) is becoming an important technology for 5G and Open RAN.
The eCPRI specification is intended to enable efficient and flexible radio data transmission via a packet based
fronthaul transport network such as Ethernet or IP.
