Cisco Coaxial Media Converter Accessories Data Sheet
Available Languages
The Cisco® Coaxial Media Converters (CMC) convert data between a coaxial cable network, a Passive Optical Network (PON), or an Ethernet network. The Cisco CMC connects to cable modems through the CATV coaxial cable network to an aggregation network through the PON or Ethernet network in the upstream direction.
Some of the Cisco CMC accessories are shipped with Cisco CMC by default. They can be selected individually by customers depending on field requirements. The accessories available are listed In Table 1.

Cable Gland with O-Ring Specifications (RJ45 waterproof connector)
The cable gland is a waterproof part used for the RJ-45 port. There are two types of cable glands: with one hole and with two holes. The cable gland with two holes should be selected when 1+1 redundancy is used for outside PON ONT connectivity.

Pads (Attenuators)
Plug-in pads produce flat (even) loss across the forward and reverse frequency spectrums. Pads are used during station balancing to adjust signal levels as needed. The (dB) loss produced is equal to the pad value printed on the top of the pad. The pads are rated for operation to 1 GHz. The Pad with “75 Ω” printed on the top will work as a 75Ohm terminator.
Forward Linear Equalizers
Forward linear equalizers produce linear tilt. A linear equalizer should be used in the plug-in input or inter-stage equalizer location if Cisco CMC output tilt does not have the desired station output tilt. The EQ value is the amount of tilt from lowest to highest frequency (52 - 1002 MHz).
Note: Cisco CMC re-uses the same linear Equalizers and Pads from Cisco GS7000/GainMaker nodes. For a more detailed specification please refer to the below URL: http://www.cisco.com/c/dam/en/us/products/collateral/video/gainmaker-amplifiers/716336.pdf
Signal Director - 2 Way Splitter and Jumper
The two-way Splitters are required to split forward RF signal to four RF output ports. The Jumpers are required to route all forward path signals to two RF output ports.
