Fibre Optic Networking - Single Mode or Multi-Mode SFP Adaptors

In a modern network environment, factors may arise that require the use of fibre optic networking equipment in conjunction with traditional networking equipment. Fibre optic networking has a range of variables, below are some details to help explain the differences and what is required when using a LILIN PoE or PoE+ switch with fibre adaptor support.

SPF stands for Small form-factor pluggable transceiver and are available in different specifications and may not be cross compatible.

For third party switches please refer to the manufactures documentation.


Multi-Mode SFP Adaptors

Multi-Mode SPF is the most commonly used type for internal networking where longer distances are required than Cat5e/Cat6 can provide. Multi-Mode fibre uses a larger diameter core than single mode fibre and is generally faster than single mode, however Multi-Mode will not allow transmission of data as far as single mode fibre.

LILIN PoE and PoE+ switches with SPF support require Multi-Mode SPF adaptors, the speed of the SPF adaptor should be rated as 1GB (Gigabyte)

LILIN recommend using the following adaptors which have been tested and confirmed with LILIN PoE and PoE+ switches


Single Mode SFP Adaptors

Single mode fibre is usually used for long distances and is least commonly used with a buildings infrastructure, single channel fibre is most commonly used for site to site connection over long distances. Single Mode usually has a lower power loss characteristic than multi-mode meaning light can travel longer distances. Single mode fibre is usually more expensive than multi-mode fibre.


***Please Note***

LILIN switches do not support Single Mode SFP adaptors.
