Adds a hot-swappable 10/100/1000BASE-T RJ45 copper link up to 100 m to Juniper SFP ports
This copper SFP module provides a single RJ-45 port for 1000BASE-T links up to 100 metres. It is 100 percent compatible with the Juniper EX-SFP-1GE-T and meets MSA industry standards. Network administrators can deploy it in Juniper switches and routers for copper uplinks or server connections. Hot-swap support allows installation without powering down the chassis.
The transceiver maintains line-rate traffic across the full 100 metre copper run using IEEE 802.3ab signalling. Auto-negotiation handles 10, 100 and 1000 Mbps speeds so mixed-speed segments stay stable. Power draw stays below 1.3 watts during continuous operation, leaving headroom in dense switch configurations. No DDM interface is present, so link health is monitored through the host platform.
Operating temperature spans 0 to 70 degrees Celsius with storage rated from minus 40 to 85 degrees Celsius. Humidity tolerance reaches 95 percent non-condensing for harsh cabinet environments. The low 1.3 watt maximum keeps airflow requirements modest in fully populated line cards. Silent passive cooling suits noise-sensitive rack rooms.

The module consumes less than 1.3W, keeping heat output low during all-day operation.
It requires an SFP slot that supports 1000BASE-T copper transceivers and complies with MSA standards.
Yes, it supports IEEE 802.3u 100BASE-TX and 10BASE-T, so it will negotiate down to 100 Mbps or 10 Mbps when connected to legacy gear.
