7.2.3 Category cable

To ensure the best performance with category cables, select a high quality category cable type, ensuring that

proper pinning and pairing requirements are observed.

・ Cat5e UTP/STP and Cat6 UTP/STP can be used, but we recommend CAT.5E HDC cable* for optimal

performance.

・ If using STP cables, connect the FG connector to a local electrical ground bonding point. Without bonding

FG to ground, the shielding feature may not effectively eliminate interference. If using UTP cables, it is still

recommend that the FG connector be used.

・ The STP cables are less affected by interference or external noise than UTP cables.

・ Connectors for long-haul transmission are the same as that of eight-core modular connector used for

Ethernet, but the transmission system is not the same so that it cannot be connected to Ethernet.

・ The maximum transmission distance of a category cables is the shorter distance of the maximum

transmission distances of transmitter/receiver/sink device connected to the MSD.

・ Pin assignments: T568A or T568B straight

・ Do not pull the cable using excessive force. The allowable tension of the category cable is 110 N.

・ Do not bend the cable at a sharp angle. Keep the bend radius four times of the cable diameter or larger.

・ Do not clamp or tie the cable tightly; leave some space allowing the cable to move slightly.

・ If you use multiple category cables, we recommend keeping a distance between the cables or not to place

the cables closely in parallel.

・ Keep the category cable running as straight as possible. Looping or coiling the cable, causes it to be more

easily affected by noise; especially when using longer cable run lengths.

・ Do not place the cable in an electrically noisy environment, since high-speed impulsive noise may couple

into the category cable. Use of a high-output radio transmission device near the MSD or remote receivers

may interfere with or interrupt video and or audio signals.

・ If the total transmission distance from the transmitter to receiver is 328 ft. (100 m) or less, up to two cable

interconnection points can be used. Products supporting Cat6A (10GBase-T) are recommended.

・ Use 24 AWG or heavier gauge cable for PoH applications.

・ The table below shows supported transmission distance for each category.

Note that specified distances may shorten depending on the conditions within the actual environment.
