Macroreer Provides Juniper Compatible Third-Party QSFP+ DAC Cable in the length of:
1-meter: http://amzn.to/2d1fr86 ( Equivalent to Genuine: QFX-QSFP-DAC-1M ) $39.99
3-meter: http://amzn.to/2cGDlGg ( Equivalent to Genuine: QFX-QSFP-DAC-3M) $49.99
The cables are hot-removable and hot-insertable. A cable consists of a cable assembly that connects directly into two QSFP+ modules, one at each end of the cable. The cables use integrated duplex serial data links for bidirectional communication and are designed for data rates up to 40 Gbps.
