Singlemode fiber has a much smaller core, only about 9 microns, so that the light travels in only one ray (mode.) It is used for telephony and CATV with laser sources at 1310 and 1550 nm because it has lower loss and virtually infinite bandwidth.
The jacket color (or connector boot color) on some cables may give you an indication. The link below gives reference to common fiber jacketing color codes. The switch/router port type may be of some use. A 1000Base-SX port is used with multimode fiber.However, it will not tell you whether the fiber core is 62.5 or 50 micron multimode fiber.Some fiber port types (or pluggable transceivers) will only work with singlemode fiber.orrect Answer by Tom Randstrom about 4 years 9 months ago.
