Four silver SFP transceiver modules with RJ45 ports

ARENTI

ARENTI 1000BASE-T SFP RJ45 Copper Transceiver 4 Pack

SKU CH-PNM9-GQ7G9

Four SFP copper transceivers provide Gigabit Ethernet over Cat5e/6 up to 100 metres with hot-plug MSA compliance

  • Up to 100 m reach over Cat5e/6 copper via RJ-45
  • Low 1.2 W power draw keeps switch thermals in check
  • Operates reliably from 0 to 70 °C (32 to 158 °F)
  • Hot-pluggable SFP MSA design enables swap without downtime
  • Fully metallic enclosure reduces EMI for stable gigabit links

4 Pack SFP RJ45 Copper Transceivers

This 4 pack provides 1000BASE-T SFP modules with RJ45 connectors for copper links up to 100m. Each transceiver fits switches with SERDES interfaces and supports Gigabit Ethernet per IEEE 802.3 and 802.3ab. The modules are hot pluggable and RoHS compliant for straightforward deployment.

Thermals Noise and Power Draw

Maximum power consumption is 1.2W per module within a commercial temperature range of 0 to 70C (32 to 158F). A fully metallic enclosure keeps EMI low while the compact RJ45 assembly maintains signal integrity. No active cooling is required so operation stays silent in normal use.

Upgrade Path and Fit

These transceivers replace fibre SFPs when copper cabling is preferred for runs up to 100m over Cat5e or Cat6. They suit networks needing MSA compliant hot swap capability and EEPROM coded compatibility with targeted switches. Buyers who need longer reach or fibre media should consider other module types.

Highlights

  • Up to 100 m reach over Cat5e/6 copper via RJ-45

  • Operates reliably from 0 to 70 °C (32 to 158 °F)
  • Hot-pluggable SFP MSA design enables swap without downtime
  • Fully metallic enclosure reduces EMI for stable gigabit links

Questions about this item

How do I install the SFP transceiver and what step is often missed?

Insert the module into an SFP cage until it clicks, then connect Cat5e or Cat6 cable to the RJ-45 port; the step often missed is verifying the host port uses a SERDES interface for 1000 BASE-T operation.

What maintenance or replacement will the transceiver need over time?

The hot-pluggable design allows removal without powering down the switch; no scheduled maintenance is required, but replace the unit if link errors appear or the metallic enclosure shows physical damage.

What is the first limit reached under sustained heavy traffic?

The 1.2 W maximum power draw and 0 to 70 °C commercial temperature range are the primary constraints; sustained loads that push the module toward 70 °C will trigger thermal throttling first.
