PWVIA RM P12 Ethernet Switches - Manual
APPENDIX 1: SFP/SFP+ FIBER ADAPTER SELECTION
The PWVIA RM P12 Gigabit switches allow the end user to provide a fiber adapter. The adapters are typically referred to as an
SFP (Small Form Pluggable transceiver) or mini-GBIC (gigabit interface converter).
Pathway catalog number PWACC SFP is an SFP 850nm Ethernet Optical Transceiver that is compatible with PWVIA RM P12,
PWVIA DIN P16 and PWVIA DIN P8, capable of 1Gbps. Catalog number PWACC SFPP is a dual-rate SFP+ 850nm Ethernet
Optical Transceiver capable of 10Gbps, compatible with the PWVIA DIN P8 and PWVIA RM P12 models. 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 Link/Status LED will light up
green
. If an incompatible module is detected,
the Link/Status 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 PWVIA RM P12 RJ45EC NONPOE and PWVIA RM P12 RJ45EC POE will work with 1000BASE-SX, 1000BASE-LX
(1Gbps) and 10GBase-SR and 10GBase-LR (10Gbps) fiber modules.
The PWVIA RM P12 RJ45EC NONPOE and PWVIA RM P12 RJ45EC POE also support SFP+ 10G Direct Attach
cables
, both active and passive. This is often the easiest and lowest-cost solutions 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.)
