2. In the case of splitters, each of the splitter output ports may be labeled “OUT” or “OUTPUT” and may include a port number at the manufacturers option. Each port must also indicate the nominal loss from the input to that port in the form “-n dB” where n is the nominal loss. The “Nominal Loss” is the manufacturer’s specifIed highest rated frequency loss rounded up to the next 0.5 dB.
3. In the case of directional couplers, the port receiving the greatest percentage of the input signal may be labeled “THRU”, “THROUGH”, “OUT”, ‘OUTPUT” or other clearly understood term, at the manufacturers option. The port receiving the lower percentage of the input signal shall he labeled “TAP” and must also be labeled with the nominal loss from the input in the form “-n dB”, where “n” is the nominal loss in dB.
4. In the case of Power Inserters, the Power port may be labeled as “DC”, “AC” or “PWR”. The port with RF only should be labeled “RF” or “TV”, and the port with power and RF should he labeled “RF + PWR”, “AC”, or other clearly understood term, at the manufacturers option. Maximum voltage must also be stated.
5. So long as the function of each port is clear and the loss from the input to each output port is clear, manufacturers may use any labeling layout they choose. See Figure 2 for an example of conforming labeling.
6. All labels must incorporate the manufacturers model number and rated bandwidth of the device.
7. Devices which do not meet the environmental criteria as specified in section 4.2 shall he labeled “For Indoor Use Only”.
8. Labeling shall be designed to be legible for a period of at least 10 years under typical environmental exposure and handling
6. Shielding Effectiveness
The shielding effectiveness of components when measured in accordance with ANSIJSCTE 48-1 2015
shall be a minimum of 100 dB.
• Power Inserters will be tested with associated power supply connected, and shielding measured along the power carrying cable and the power supply.
7. Surge Withstand
The surge withstand of components when measured in accordance with ANSL/SCTE 81 2012 shall be at
minimum compliant with IEEE C62.4l-199l Category A3, Ring Wave 6KV at the F Ports. Power
Inserter and associated power supply shall be connected together and subjected to IEEE C62.41-1991
Category B3, Combination Wave 6KV applied to the Mains plug.
8. Intermodulation Distortion
The Intermodulation Distortion of the device must he better than —95 dB relative to the injected signal when tested in accordance with SCTE 145 2013. Intermodulation Tests shall be performed immediately after Surge Withstand Test in order to test for any Ferrite Magnetization detrimental effects.
5. Environmental
1. Applicability
The following requirements apply for all devices. Devices which do not meet the requirement in section 4.2 shall be labeled “For Indoor Use Only”.
2. Salt Spray
The device must meet all performance requirement as outlined in section 4, after a minimum of 1000 hours of salt spray when tested in accordance with ANSL/SCTE 143 2013. The device must exhibit corrosion penetration of less than 50% metal thickness, and show no evidence of internal damage. F Ports shall be appropriately sealed during testing to prevent salt water compound entry via the ports.
3. Temperature
The device must meet all performance requirement during and after temperature cycles ranging from –
40°F (-40 °C) to +140 °F (+60 °C) inclusive (Outdoor Rated Devices), and +32 °F (0 °C) to +140 °F
(+60 °C) inclusive (Indoor Rated Devices) with 95% relative humidity at both types of devices at the high
temperature limit.
Temperature Cycles shall be:
• 2 hours at the low limit
• I hour transition to high limit
• 2 hours at the high limit
• 1 hour transition to the low limit; repeat for 15 cycles
