Removing the SFP+ Module:
Pull the bale-clasp latch with index finger towards downward
direction and gently pull the SFP+ module from the port.
Connect CPRI Fiber optic cables.
CPRI SFP+ module kits
SFP+ module kits allow connection of 2 GHz/3 GHz cnRanger RRHfrom cnRanger 800 BBU over optical
fiber cable. Use 10Gbps SFP+ module (SFP-10G-SR) to connect to 2 GHz/3 GHz cnRanger RRH. Maximum
length of optical fiber cable shall not exceed 300 meters. Use Multimode LC- LC outdoor optical fiber
cable between 2 GHz/3 GHz cnRanger RRHand cnRanger 800 BBU.
Cambium Networks CPRI fiber cable part number (N000000L131A) is recommended for use between the
2 GHz/3 GHz cnRanger RRH and junction box in order to provide optimal fit through weather proofing
gland. From junction box long length CPRI cables can be extended depending on the lengths.
Cambium does not supply long length optical fiber cables along with SFP+ module kits. Recommended
cable lengths and specifications are as shown in
