Myricom has qualified the transceivers from each source for performance and reliability. Some of the SFP+ Transceivers sfpcables.com supplied by Myricom have Myricom labeling, as shown, and some have the manufacturers standard labeling.The 10GBase-SR transceivers operate at an 850nm optical wavelength, and are designed for 50?m (50/125) multimode fiber at distances of 26-82m depending upon the fiber, or at distances up to 300m over 50?m 2000MHz·km multimode fiber.CWDM Pluggable Optical Transceivers are designed to meet specific networking protocols and media requirements. They support single-mode dual fiber applications with Coarse Wave Division Multiplexing (CWDM) wavelengths. CWDM Pluggable Optical Transceivers increase network capacity by transmitting multiple data channels using separate optical wavelengths (1270nm to 1610nm) on the same fiber pair. These wavelengths are compliant to the ITU G.694 CWDM standard.The BLADE Network Technologies 10 Gigabit Ethernet Fiber SFP+ Transceivers QSFP-H40G-?CU1M – Compatible Cisco 40GbE QSFP+ QDR Direct-Att?ach Copper Cable 1m short range module (IBM part number 46C3447) is an SFP+ 10 Gigabit Ethernet small-form factor, hot-pluggable transceiver that plugs into a high-speed data port.
