# Product Description

   QFX-QSFP-DAC-1M is Juniper Compatible 40GBASE-CR4 QSFP Passive Twinax Cable, operating over passive copper cable. Our Juniper QFX-QSFP-DAC-1M Compatible product datasheet and price is based on our 40G-PDAC-QSFP-1 module. 40G Passive Twinax cable is equipped with Juniper standard compatible QSFP+ transceiver assembly at each end of cable. As passive Twinax cables do not support any electrical transmission signal boosting on regeneration, length of 40G Passive Twinax cable is limited up to 1 meter, which is enough to support 40G connections within same or neighboring equipment racks. 40G Passive Twinax cable supports 4 separate fully duplex copper data lanes, which support 2.125-41.2 Gbps multi-rate communication and such applications as 40G Ethernet (41.25Gbps), 10G Ethernet (10.31Gbps). Most popular applications of 40G Passive Twinax Cables are cost-effective close-range interconnections within equipment room of telecom operators or data centers, interconnecting LAN or SAN applications with speeds up to 40G.

   Juniper QFX-QSFP-DAC-1M 40GBASE-CR4 QSFP direct-attach copper cable is CE/RoHS certified and it is compliant with product safety standards. We perform compatibility tests for Juniper compatible QFX-QSFP-DAC-1M Cable with latest platforms of Juniper networking equipment, which allows us to encode Passive Cable EEPROM memory to be compatible and work seamlessly with Juniper platforms. However, our Juniper 40GBASE-CR4 QSFP Passive Cable complies to QSFP+ Multi Source Agreement SFF-8436 as well. Because our focus is providing top quality service, we are performing serious quality checks before delivery of products to our customers. As a result, we do parameter measurements and Passive Copper Cable EEPROM memory data validation tests. For Passive Copper Cables there can be situations where custom interconnection solutions are required, where one end of the cable is used in one Brand of equipment while the other end of the cable is used in another Brand of equipment and special coding need to be used at the each side of the cable end for smooth interconnection. If You have any other questions about our Juniper QFX-QSFP-DAC-1M Compatible product datasheet and price, please do not hesitate to contact Us– we will be happy to assist!
