# Product Documentation
Multi-Vendor MSA Compatible 40G-PDAC-QSFP Datasheet

Extreme Networks Compatible 40GB-C0.5-QSFP 40G Passive Twinax Cable is based on our product 40G-PDAC-QSFP. When You will order it will be encoded to be compatible with Extreme Networks equipment and it will be labeled with part number: 40G-PDAC-QSFP-0.5-EX, where EX means Extreme Networks Compatible. Above You can download datasheet of our 40G-PDAC-QSFP product.

# Product Description

40GB-C0.5-QSFP is Extreme Networks Compatible Passive Twinax Cable, operating over passive copper cable. 40G Passive twinax cable is equipped with Extreme Networks 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 0.5 meters, 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.

Extreme Networks compatible 40GB-C0.5-QSFP direct-attach copper cable is CE/RoHS certified and it is compliant with product safety standards. We perform compatibility tests for Extreme Networks compatible 40GB-C0.5-QSFP Cable with latest platforms of Extreme Networks networking equipment, which allows us to encode Passive Cable EEPROM memory to be compatible and work seamlessly with Extreme Networks platforms. However, our Extreme Networks compatible 40GB-C0.5-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 equipment while other end of the cable is used in another Brand equipment and special coding need to be used at each side of the cable end for smooth interconnection. We will be glad to hear Your requirements and our sales team will check all relevant details with You during ordering procedure – Contact us.
