What and Ethernet Copper 10BASE-T SFP+ Transceiver Module?

10Gtek SFP+ 10GBASE-T copper transceiver is a high-performance integrated duplex data link for bidirectional communication over copper cable used to implement 10G Ethernet transmission 10GBASE-T, which is that it allows users to capitalize on their existing Category 6 (CAT.6A) and Category 7 (CAT.7) copper cabling system. Its interface is RJ-45, which supports both shielded twisted pair and unshielded twisted pair. Its maximum transmission distance is up to lengths of 30 meters with a respectable maximum throughput of 10 GB/s.

This is the first SFP+ transceiver offering 10 GB/s communication over this media type. 10Gtek, a leading supplier of compatible optics and cables for high-performance data center servers and storage systems, has been providing the SFP+ Copper Transceiver 10GBase-T, Cat 6A/7, 30M since 2016.

10Gtek ASF-10G-T Series

10Gtek 10BASE-T copper transceivers are available in 30m and 80m editions. The 30m model uses the PHY Broadcom BCM84891 chip, while the 80m model is powered by the Marvell 88E1111 chip. Both follow IEEE 802.3 MSA requirements at the highest standards. The 10GBase-T copper transceiver module is a high-performance integrated duplex data link for bi-directional communication over copper cable. Low energy consumption and high durability – The energy dissipation and heat-conducting gasket of less than 2.5 W provide a superior heat dissipation function to dissipate the module’s heat and increase its lifetime.

Comparison: 10GBASE-T Cabling vs. 10G SFP+ DAC (Direct Attach Copper)

The comparison shows that both 10GBASE-T cabling and 10G SFP+ DAC have advantages. SFP+ copper cabling is more suitable for use in data centers, the 10GBASE-T cabling will be better for cabling cabinets due to its flexibility and low cost.

---

Does the 10GBASE-T module tend to heat much during operation?

The temperature values tend to be very high. The estimated power consumption of the 10GBASE-T is 1.5w. Its heat generation is very high, and the high temperature can be felt during use. The switches with multiple SFP+ interfaces cannot be fully equipped with 10GBASE-T. As for the maximum number of 10GBASE-T that can be fitted, it depends on the switch capability.

What is a Media Converter?

A Media converter is a specific network device that converts the electrical signal used in a copper cable to a light signal for optical fiber cabling and vice versa. Fiber optic connectivity is essential if the distance between two network devices exceeds the transmission distance of copper cabling.

They were first introduced into the industry in the 1990s and played a significant role in the types of cabling fiber associated with the existing copper-based cabling system. They were introduced into the industry in the 1990s and played an essential role in the types of wiring fibers related to the current copper-based wiring system.

Testing with a pair of SFP Modules:

We used a none branded 1.25G 14490/1310 SM (Single-Mode) SFP LC and an RJ45 2.5G TP-LINK SM SFP module. In our simple test, we checked maximum throughput using Speedtest by Ookla Windows App connected to a nearby local ISP server.

Throughput test with Ookla Speedtest App

Based on the Internet plan of 1Gbps / 100Mbps, our satisfactory results show that both SFPs are fully compatible with the SFP+ ports reaching a maximum throughput of ~940Mbps / 110Mbps.

G0200-SFP ( 2.5Gbps Throughput configuration )

Notable credits to aka as itfan from HT magazine website for confirming another possible working configuration that works with Israel Bezeq Fiber telecommunication company based on Gigabyte Passive Optical Networks (GPON) technology. According to his testing, it’s possible to achieve a maximum throughput of 2.5 Gbps by combining a pair of SFP modules. This will require the following components/elements:
