Description
Transition Networks’ 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, Transition
Networks SFP28 modules are also Compliant with all Cisco SFP28 based routers and switches, as well as Cisco’s
IOS software. Transition Networks 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
”
.

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.
