SFP

Sinara Core Devices (Kasli, Sayma, Metlino) use SFP modules for several purposes.

• Core Device (eg Kasli) to Ethernet switch
• Synchronization of Core Devices via DRTIO

Core Device to Ethernet switch

Use a transceiver rated for at least 1 Gb data rate. Examples include the following.

• SFP to Copper RJ45 (1000BASE-T)SFP-GB-GE-T (fs.com #11773)
  • tested with Kasli v1.0
• SFP to fiber transceiver pair
  • fiber: SM 9/125 OS2 single-mode simplex fiber patch cable with connectors LC/UPC-LC/UPC (not angle polished) (eg sf.com p/n SM-LCU-LCU-SX-FS-2M-PVC)
  • 1000Base-X SFP transceiver A: SFP-GE-BX (Tx at 1310 nm Rx at 1490 nm) (eg sf.com p/n 20184)
  • 1000Base-X SFP transceiver B: SFP-GE-BX (Tx at 1490 nm Rx at 1310 nm) (eg sf.com p/n 29895)
  • tested with Kasli v1.0

DRTIO Synchronization

For best performance with clock recovery use single mode bi-directional transceivers with two-channel wavelength division multiplexing (BiDi). The SFP modules at either end of the fiber differ based on the laser diode color and grating configuration. For DRTIO it is critical to use transceiver rated for at least 10 Gb data rate.

The following transceivers work as of 7/2021.

• FS P/N: SFP-10G-BX #36351 :: Cisco SFP-10G-BXU Compatible 10GBASE-BX10-U BiDi SFP+ 1270nm-TX/1330nm-RX 10km DOM LC SMF Transceiver Module
• FS P/N: SFP-10G-BX #36353 :: Cisco SFP-10G-BXD Compatible 10GBASE-BX10-D BiDi SFP+ 1330nm-TX/1270nm-RX 10km DOM LC SMF Transceiver Module
• tested with Kasli v1.1
