• Longer lengths available on special order
Key Features:
• Lightweight, flexible, fiber cables
• Very low latency
• No problems with dust in fiber-cable ends
• No laser safety issues
These are the preferred cables for 10G Myrinet clusters and for switch-to-switch connections in Myri-10G switch networks with more than 512 host ports.
Specifications:
Myri-10G components with QSFP (Quad Small Form factor Pluggable) ports have "QP" product codes, such as the 10G-PCIE-8A-QP NIC or 10G-SW32LC-16QP switch line card. The QP ports employ XAUI signaling, 4 lanes in each direction of 3.125 GBaud signals, 8b/10b encoded, for a data rate of 10 Gb/s in each direction. See this Guide to Myri-10G PHYs (pdf).
These industry-standard QSFP-terminated Electrical-Optical-Electrical (EOE) cables are supplied to Myricom from multiple sources. Myricom has qualified the EOE cables from each source for performance and reliability.
Consistent with the QSFP multi-source agreement (MSA), the QSFP cable ends have a common mechanical specification, pinout, and management interface. The cable itself has four multimode fibers in each direction. The standard cables sold by Myricom are Riser Rated (OFNR). Plenum Rated (OFNP) cables are available at additional cost on special order.
Latency: The optical-fiber transceiver in each cable end has neglible latency. The "time of flight" latency in the fiber is ~5ns per meter.
Power: 1W typical per cable end.
Reduction of Hazardous Substances: These devices are RoHS-compliant lead-free (RoHS-6).
