Single-mode fiber needs many more splices than multimode. Outside plant (OSP) single-mode fiber links often require splicing shorter lengths of cable or drops off of a backbone cable. These OSP cables are usually fusion-spliced. Indoors, connectors are usually spliced onto single-mode fiber for termination.

For almost a year, I’ve been covering the expansion—explosion?—of optical fiber’s applications. Data speed is a factor in almost all of these networks; networks are getting progressively faster. READ MORE
January 2016
In the past year, fiber optics underwent some important developments, some technical and some market-related. For those of you working in fiber optic network design and installation, the changes present opportunities and challenges.

Recent columns have focused on what is happening with dark fiber, that which is being “lit” to become the backbone of the world’s communications systems. Dark fiber connects data centers, cell towers, cities, towns, governments and people. The dark fiber business is booming and creating more work for many of us.

Last month, I wrote about how fiber was being used to expand bandwidth for cellular systems, connecting cell towers to the phone network and antennas on the tower to the base electronics. That helps our phone coverage when we’re driving or walking outside. But, as we all know, cell coverage can be poor inside buildings.
