Juniper EX2300 Series Hardware Guide

Cable Specicaons
EX Series switches support SFP+ passive DAC cables. The passive Twinax cable is a straight cable with
no acve electronic components. EX Series switches support 1 m, 3 m, 5 m, and 7 m long SFP+
passive DAC cables. See Figure 49 on page 78.

The cables are hot-removable and hot-insertable: You can remove and replace them without powering
o the switch or disrupng switch funcons. A cable comprises a low-voltage cable assembly that
connects directly into two 10-Gigabit Ethernet ports, one at each end of the cable. The cables use high-
performance integrated duplex serial data links for bidireconal communicaon and are designed for
data rates of up to 10 Gbps.
