Appendix 1: SFP Fiber Adapter Selection
The VIA16 allows the end user to provide a fiber adaptor. The adaptors are typically referred
to as an SFP (Small Form Pluggable transceiver) or mini-GBIC (gigabit interface converter).
Pathway part number 6799 is an SFP 850nm Ethernet Optical Transceiver that is compatible
with VIA10, VIA12 and VIA16. The dual-mode fiber is also compatible with the 6706 VIA5 +
Fiber. These fiber links can go up to 550 m (1800 feet) without issue. In some situations, the
run lengths may lead you to choose a different SFP. Follow these guidelines when choosing
your SFP:
1.
The form factor must be stated as SFP (not SFP+, XENpack or others).
2.
The fiber connector is LC Duplex.
3.
The SFP must support Optical Gigabit Ethernet (typically referred to as 1000BASE-
SX or 1000BASE-LX)
4.
The SFP must match the type of fiber installed, either Single Mode or Multi-Mode.
5.
The SFP must support the distance required, which in turn determines the optical
wavelength. 850nm is typically used for runs up to 550m, while 1310nm is typically
used for runs up to 10km.
We strongly recommend each end of the connection use an identical SFP.
When the SFP module is inserted in the switch, the corresponding Link/Activity LED will light
up green. If an incompatible module is detected, the LED will light up red. In Pathscape, the
Subdevice properties panel will indicate the link status, SFP Module Type (1000BASE-LX or
1000BASE-SX), as well as the LLDP Partner.
NOTE: The VIA16 will only work with 1000BASE-SX or 1000BASE-LX fiber modules.
When connecting a VIA to another manufacturer’s switch using fiber, please bear in mind
that some switches check the manufacturer’s ID, as announced by the SFP module, and will
only connect to a matching brand. VIA switches do not perform a manufacturer’s ID check,
and should work with any SFP module meeting the criteria above (Cisco, Finisar, Netgear,
etc.)
