5.1.2 Interface for Optical Cable to Radio 4408 Unit
The 1 and 2 interfaces provide connections to optical cables (with outer diameter 4.5–5.5 mm, and comply with
standard G657A2) for traffic and timing signals between the radio and the main unit. An SFP is used to connect the optical
cable to the radio.
Note: The radio uses SFP modules for optical transmission and optical radio interfaces on Data 1 and Data 2.
Only SFP modules approved and supplied by Ericsson must be used. These modules fulfill the following:
– Compliance with Class 1 laser product safety requirements defined in standard IEC 60825-1
– Certification according to general safety requirements defined in standard IEC 60950-1
– Functional and performance verified to comply with Radio System specifications
Recommended SFP modules are obtained from the product packages for the Radio System and the Main Remote
Installation products. For more information about SFP modules, see Spare Parts Catalog and Site Installation Products
