Single Mode
The fiber optic cabling standard that, when used in conjunction with a 1300 nm laser light, can
transfer data up to 10 km between devices. When used in conjunction with a 1550 nm laser
light, single mode cabling can transfer data over 10 km.
See also multimode, LWL, ELWL, and XLWL.
SI
Sequence Initiative.
SNMP
Simple Network Management Protocol. An internet management protocol that uses either IP
for network-level functions and UDP for transport-level functions, or TCP/IP for both. Can be
made available over other protocols, such as UDP/IP, because it does not rely on the
underlying communication protocols.
See also Community (SNMP).
SNMPv1
The original SNMP, now labeled v1.
