OVERVIEW

External Ultra2 LVD SCSI Cable

Constructed of double-shielded twisted pair, these cables transfer data at up to 80 MB per second across the entire SCSI bus.

The External Ultra2 LVD SCSI Cables are fully compatible with older SCSI devices, including Ultra-Wide single-ended SCSI devices. And they can increase your SCSI bus length to up to 12 meters!

Internal Ultra2 LVD SCSI Cable

Use the Internal Ultra2 LVD SCSI Cables for internal single- ended or differential SCSI applications requiring twisted pairs.

These cables feature flat sections and loose, unbonded twisted pairs that are perfect for connecting multiple internal devices. And they terminate to industry-standard 0.025" IDC connectors.

Ultra2 LVD SCSI Terminators

Select either internal or external models that support termination for both LVD and/or single-ended SCSI buses. All models support the 80-MB-per second LVD specification.

Connect the internal terminator directly on the internal flat ribbon cable assembly.

The external terminators feature an LED that identifies the bus being terminated for LVD or single-ended devices. And to ensure secure VHDC1 and Micro D68 connections, thumbscrew connections are provided.

LVD SCSI Cables and Terminators specifications

Black Box LVD SCSI cables and terminators are essential components in high-speed data transfer applications, particularly in environments that require reliable communication between servers, drives, and other peripherals. LVD, or Low Voltage Differential signaling, enhances performance while improving signal integrity over traditional Single-Ended SCSI systems. These cables and terminators play a crucial role in facilitating seamless connections while minimizing interference and data loss.

One of the main features of Black Box LVD SCSI cables is their ability to support data transfer rates of up to 80 MBps. This increased bandwidth is vital for applications that demand high performance, such as video editing, server backups, and large database management. Additionally, these cables are designed with a maximum length of 12 meters, ensuring that data can be transmitted over longer distances without degradation.

The technology behind LVD SCSI is focused on lower voltage levels, which reduces power consumption and electromagnetic interference. This makes Black Box LVD cables ideal for environments where multiple devices are in close proximity, as they offer resistance to cross-talk and noise. The differential signaling utilized in LVD also allows for better signal integrity, ensuring reliable data transfers even in electrically noisy environments.

Black Box terminators are designed to complement their LVD SCSI cables, providing the necessary impedance matching and preventing signal reflections that can corrupt data. These terminators come equipped with a secure connection, ensuring that the SCSI bus remains stable and that devices connected to the system can communicate effectively without disruptions. A key characteristic of these terminators is that they can be used in either active or passive configurations, allowing for flexibility based on specific system requirements.

In terms of construction, Black Box LVD SCSI cables are built using durable materials to withstand various environmental conditions. The connectors are designed for easy plug-and-play installation, allowing users to quickly set up their systems without requiring extensive technical knowledge. Additionally, these cables and terminators adhere to industry standards, ensuring compatibility with a wide range of SCSI devices.

Overall, Black Box LVD SCSI cables and terminators are engineered to provide high-performance data transfer capabilities, making them a popular choice for businesses and professionals that rely on efficient and reliable storage solutions. With their advanced technology, robust construction, and compatibility, they remain a critical investment for any organization focused on enhancing their data handling capabilities.
