The VIA8 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 VIA12, VIA16 and VIA8, capable of 1Gbps. Part number 6798 is a dual-rate SFP+ 850nm Ethernet Optical Transceiver capable of 10Gbps, compatible with the VIA8 and VIA12 model 675X. 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 or SFP+ (not XENpack or others).
2. The fiber connector is LC Duplex.
3. The SFP must support Optical Gigabit Ethernet (typically referred to as 1000BASE-SX, 1000BASE-LX, 10GBase-SR or 10GBase-LR)
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, as well as the LLDP Partner.

NOTE: The VIA8 will only work with 1000BASE-SX, 1000BASE-LX (1Gbps) and 10GBase-SR and 10GBase-LR (10Gbps) fiber modules.

The VIA8 also supports SFP+ 10G Direct Attach cables, both active and passive. This is often the easiest and lowest-cost solution to connect multiple switches if they are close together.

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.)
