Which end of the cable should be connected to the fiber optic attenuator
As for placement, installing the attenuator at the receiver end of the link makes it more convenient to measure and adjust the power level with a meter. Plus, it ensures that reflectance will not affect the transmitter. There are two basic types of attenuators: fixed and variable. Installing common plug-style (buildout) male-to-female attenuators involves mounting them on one end of a fiber optic cable so that the cable may be inserted into a patch panel, or connected to receiving equipment.

Does broadband fiber optic cable require an optical module
The answer is actually no—fiber optic equipment differs significantly from cable setups. EPON, or Ethernet Passive Optical Network, is a fiber-optic network standard that uses Ethernet packets to deliver high-speed data, voice, and video services. Explores the differences between Singlemode and Multimode fibers, along with Simplex vs. Du-plex configurations, to help you make. It transmits optical signals through fiber optic cables and converts them back into electrical signals at the receiving end. Transceivers can be built-in to an Ethernet switch or as an accessory device via SFP/SFP+ (small form-factor pluggable) modules.
