July 30, 2020 — In response to 5G network deployment needs, FIBERSTAMP, the leader beyond 200G in the optical communications industry, began a comprehensive upgrade of the design of xWDM transceivers above 10G as early as 2018, and now officially launched a full range of 5G fronthaul xWDM transceivers, including 10G CWDM, 10G DWDM, 25G CWDM, 25G DWDM and 25G LWDM series.

The 5G fronthaul network has stringent requirements on the bandwidth and delay of the bearer network. The current solution gives priority to using the eCPRI interface, and the delay requirement is less than 100µs. FIBERSTAMP's 5G fronthaul series xWDM transceivers comply with CPRI/eCPRI standards and are widely used in 25G Ethernet and 5G fronthaul networks. They have excellent characteristics such as high reliability and low latency. In order to meet the requirements of 5G fronthaul outdoor applications, FIBERSTAMP has completed the formulation and implementation of product design standards under industrial temperature environments. All of the newly launched 5G fronthaul xWDM transceivers meet industrial temperature standards and perform well in harsh outdoor environments.

FIBERSTAMP's full range of 5G fronthaul xWDM transceivers are shown as the following list.

  • 10G CWDM SFP+ series, 1470nm-1610nm, 40km, < 1.8W, I-Temp
  • 10G DWDM SFP+ series, C18-C61, 40km/80km, < 2W, I-Temp for 40km and E-Temp for 80km
  • 25G CWDM SFP28 series, 1270nm-1370nm < 1.2W E-Temp, 1470nm-1570nm < 1.8W I-Temp
  • 25G DWDM SFP28 series, C18-C61, 10km, < 2W, I-Temp
  • 25G LWDM SFP28 series, 9 LAN-WDM options, 30km w/o FEC or 40km w/ FEC, < 1.8W, I-Temp

FIBERSTAMP's 5G fronthaul series xWDM transceivers can also be combined with passive xWDM components to form a more complete 5G fronthaul xWDM solution that uses a pair or one fiber to realize multiple AAU to DU connections, and greatly saves fiber resources for operators and solves the problem of fiber resource shortage.
