MiniSAS Cables power to enable active cables and EEPROM

This 1/2 meter long cable uses 30 AWG wires and is intended for internal use. It has a single 36-pin SFF-8087 male Mini-SAS plug (with locking latch) on one end and has four 7-pin SATA female plugs (with locking latches) on the other, allowing you to connect four SATA drives to an SAS controller. This is a Forward Breakout cable, meaning that it is intended to connect to a host/controller on the SAS end and to drives on the SATA end.Several forward-looking solutions were adopted to ensure future enhanced connectivity. MiniSAS Cables(high-density) connector was chosen for next generation interconnects (including the 12 Gb/s data rate to be defined in the upcoming SAS-3.0 tandard), which had provisions for power to enable active cables and EEPROM for management. All these solutions, however, still did not address the large number of MiniSAS Cables interconnects deployed in the field which were limited to the 10m passive copper reach. Despite distinct benefits offered QSFP-H40G-​CU1M – Compatible Cisco 40GbE QSFP+ QDR Direct-Att​ach Copper Cable 1m by SAS to OEM’s, integrators and end users, the technology has been somewhat curtailed by the limited reach of supported copper cabling.

SFP 1.25Gb/s switched backplanes

RoHS-compliant transceiver module is able to access the physical layer IC (PHY) via I2C interface. Additionally, the device features Baseline Wander correction to recover data in a worst-case network environment, and an automatic medium-dependent interface crossover (auto-MDIX) feature. In 1000BASE-T and 100BASE-TX modes, the transmit data stream is scrambled to reduce radiated emissions and to ensure that there is no correlation between symbols in the data stream.Supporting 10/100/1000 Mbps data-rate in excess of 100 meters (325 feet) reach over UTP Category 5/5e cables, the robust SFP-1GBT-05 transceiver module is ideally suited for implementing small form-factor Network Interface Cards (NICs) and uplinks. As such, it is highly appropriate for use in such high-density applications as LAN 1000BASE-T, switch-to-switch interfaces, switched backplanes, blade servers, gaming devices, and router/server interfaces.The Model OTOLS-13, OTOLS-15 and OTOLS-CW small form pluggable (SFP) transceivers operate at 10GTEK offers SFP 1.25Gb/s and are compatible with gigabit Ethernet and 1000BASE-T standards. The link uses a two-wire serial communication protocol based on current industry requirements. The compact metallic QSFP-H40G-​CU1M – Compatible Cisco 40GbE QSFP+ QDR Direct-Att​ach Copper Cable 1m enclosure includes a standard LC connector and can be ordered for 1310nm, 1550nm, or CWDM transport.

versions of the QSFP+ module are available

QSFP+ is a hot-pluggable high-density transceiver which provides 4 channels of traffic in each direction (Tx and Rx). QSFP+ supports up to 10.5 Gb/s per channel for applications such as 40G Ethernet and InfiniBand 4xQDR. Both multimode and single mode versions of the QSFP+ module are available, as well as QSFP-based active optical cables (Quadwire QDR and Quadwire FDR).The Quad Small Form-factor Pluggable (QSFP) interconnect system from TE Connectivity (TE) is a four-channel package, offering 3 times the density of traditional SFP ports and supports speeds up to 10Gb/s per channel (suitable for 8G Fiber Channel and 10G Ethernet). The system is ideal for switches, QSFP-H40G-​CU1M – Compatible Cisco 40GbE QSFP+ QDR Direct-Att​ach Copper Cable 1m and host bus adapters (HBA's) where bandwidth is essential.

Excel OM1 Duplex patch leads are generally available

The PVC jacket used on Dueltek fibre cables is LSZH (Low Smoke Zero Halogen). LSZH cable reduces the amount of toxic and corrosive gas emitted during combustion. This type of material is typically used in poorly ventilated areas such as aircraft or rail cars, but it is becoming a more popular choice for green installations & nvironmentally conscious consumers.Plenum duplex fiber cable is composed of a tight buffer, aramid yarn, and a PVC outer jacket. All component materials meet the EU RoHS and REACH Directive standards.These plenum duplex fiber cables are available in 12 TIA standard colors or special order colors. The fiber cable is UL Listed OFNP for use in ducts, plenums and air-handling spaces. Standard surface print denotes construction, NEC rating, and fiber type, and includes footage markers. Custom print can also be accommodated.Excel OM1 Duplex patch leads are generally available from stock in lengths from 1 to 30 metres. For requirements which may vary from this, such as specific length, colour or labelling requirements, please contact your local Excel distributor. Not all cable types and lengths are available from stock in both grey and orange please check with you nearest sales office for details.

QSFP+ transceiver can replace up to 4 standard SFP+ transceivers

Copper cabling is typically a bulky solution with a limited reach of 3 to 15 meters at 10 Gbps/lane data rate. A fiber optic QSFP+ solution provides a longer reach and a tighter bend radius, maintains the company.Molex's Quad Small Form-factor Pluggable (QSFP+) solution is designed for high-density applications. Components of the system include the Electro Magnetic Interference (EMI) shielding cage, active optical cables (AOC), passive copper cable assembly, active copper cable assembly, optical MTP cable assembly, optical loopback, 38-circuit SMT iPass host connector, and stacked integrated connectors and cages.The SFF-8685 document specifies a transceiver mechanical form factor with latching mechanism, host-board electrical-edge connector and cage.
