Amphenol CS-NBC0DSASLB-3DB 4x External HD Mini-SAS Loopback Adapter Module for SFF-8644 Mini-SAS HD Port Testing - 3dB Attenuation & 0W Power Consumption [Copper+Optical Ready]

Exclusively at Cables on Demand -- Mini-SAS HD Loopbacks from Amphenol High Speed Interconnects!  Genuine Amphenol 4x External HD Mini-SAS loopback adapter modules provide the ideal 12G SAS 3.0 rated port testing solution for SFF-8644 compliant (aka IPASS+™ HD) 4x HD Mini-SAS enabled ports (12.0 Gbps x 4 channels / 48.0 Gbps aggregate).

This low-profile passive HD Mini-SAS loopback "cable" consists of an integrated transceiver module, built within a standard SFF-8644 HD Mini-SAS connector body, whereby the input and output channels are shorted or "looped back" to one another on the internal double-sided PCB. To fully emulate the typical insertion loss (attenuation) characteristics of a commonly deployed medium-length Mini-SAS HD copper cable assembly of approximately 3.0 decibels, an impedance-matched 3dB resistive load is included in the circuit -- all while consuming no more than 0.0 Watts of power in the process!

Compatible with both copper and optical HD Mini-SAS enabled ports, our loopbacks perfectly replicate the performance range typical of a successful bi-directional 48G 4-lane SAS connection between the latest HD Mini-SAS equipped adapter cards, blade servers, stand-alone drives, networked storage arrays, routers, and switches. Protocol-independent design ensures compatibility with all present and emerging signal standards, making this Amphenol-brand Mini-SAS HD Loopback a future-proof and essential component of your IT equipment tool-kit.
