SFP-ETRx-4

10/100/1000 BASE-T Copper SFP Transceiver

SFP-ETRx-4

Ma transceiver a OPT-ETRx-4 Copper Small Form Pluggable (SFP) amachokera ku SFP Multi Source Agreement (MSA). Amagwirizana ndi miyezo ya Gigabit Ethernet monga momwe zafotokozedwera mu IEEE STD 802.3. 10/100/1000 BASE-T physical layer IC (PHY) ikhoza kupezeka kudzera mu 12C, zomwe zimathandiza kuti pakhale mwayi wopeza makonda ndi mawonekedwe onse a PHY.

OPT-ETRx-4 imagwirizana ndi 1000BASE-X auto-negotiation, ndipo ili ndi chizindikiro chosonyeza ulalo. PHY imazimitsidwa pamene TX disable ili pamwamba kapena yotseguka.
