Waterproof female star chain extension cable

The core physical layer rate of Starlink Cable is 1000Mbps (1Gbps) full-duplex (Gen1/Gen2 standards), and the Gen3 version is upgraded to 2000Mbps (2Gbps) or higher. However, in practical applications, it is limited by the bandwidth of satellite links. It usually operates within the range of 100 to 300Mbps. The following are the detailed specifications and key notes:
I. Official Standard Rate and Version Differences
Starlink version cable type Physical layer rate line gauge/Category Standard length remarks
Gen1/Gen2 Cat5e/Cat6 1000Mbps(1Gbps) 24-26AWG 15m(49.2ft) Supports 802.3af/at PoE (15-30W)
Gen3 (Residential) Cat6a/Super Category 6 2000Mbps(2Gbps) 24AWG 15m(49.2ft) Supports 802.3bt PoE++(up to 90W)
Gen3 (Enterprise) Customized industrial-grade 2500Mbps (2.5Gbps) optional 24AWG + shielding up to 75m, supports fiber expansion, redundant power supply

The flat high-performance version custom flat Cat6 1000Mbps 26AWG 5-15m is suitable for installing Starlink in small Spaces
Core standards: All official Starlink cables comply with the IEEE 802.3ab (Gigabit Ethernet) standard, supporting adaptive rates of 10/100/1000Mbps. The Gen3 version is compatible with 2.5GBASE-T to match higher satellite bandwidth requirements.
Ii. Analysis of Rate Limiting Factors
The difference between the physical layer and the actual application rate
Physical layer upper limit: The cable itself supports 1Gbps/2Gbps full-duplex (transmission and reception can reach 1Gbps/2Gbps simultaneously)
Actual bottleneck: Limited by satellite link bandwidth (Gen1/Gen2:100-350Mbps; Gen3:200-500Mbps) and router forwarding capacity Starlink
Typical user rate: In actual use, the cable transmission rate is usually between 100 and 300Mbps, fully meeting the requirements of satellite Internet
2. Key factors affecting rate
Line length loss: Standard 15m length loss is less than 3dB, and the rate remains at full capacity. The 45m ultra-long version has a loss of less than 8dB and can still stably operate at 1Gbps
Shielding quality: Outdoor cables adopt multi-layer metal shielding to reduce electromagnetic interference and ensure the integrity of high-speed signals
PoE power supply impact: Power and data are transmitted in different pairs of lines without interfering with each other and will not reduce the data rate
Connector quality: The official uses custom waterproof RJ45 connectors with low contact resistance to ensure no signal attenuation Starlink
