Micro-ducts can also be placed directly into larger telecommunications conduits or can be factory assembled into a composite unit of multiple micro-ducts.

The underground placing methods described in this document are intended as guidelines.

National, state, local, and corporate specifications, regulations, and industry recommendations normally take precedence over these. It is impossible to cover all the conditions that may arise during a placing operation. Individual company practices for placing fiber optic cable should supersede any conflicting instructions in this document whenever they do not exceed the cable's optical and mechanical performance specifications.

The methods used to place fiber optic cables in ducts are similar to those used to place copper cable. Optical cable is a high capacity transport medium that is sensitive to excessive pulling force, tight bends, and crushing forces, therefore, proper care must be taken during the installation procedure.

Fiber optic cables are ordered in specific lengths as calculated by an OSP (Outside Plant) Engineer. Their lengths are determined by measuring the distance between splice manholes plus the excess cable length required for racking the cable at all manhole locations and slack storage for maintenance. Additional cable length is required at each splice manhole to reach to the actual splice location (often in a trailer or tent adjacent to the manhole). In addition, extra

length should be included in the ordered length to be available if errors are made during the splicing operation. If the excess splice length is not known, the splicing foreman should be consulted. Never cut a fiber cable without first consulting the OSP Engineer responsible for the job.

All optical fiber cables are sensitive to damage during shipping, handling, and installation.

Some of the important parameters that need special attention during cable installation are:

Cable bending radius: Optical fiber cables are designed with a minimum bending radius and maximum tensile strength. The cable should never be bent below its minimum bending radius. Doing so can result in bending losses and/or breaks in the cable's fibers. Generally the minimum bending radius of a fiber cable under load is 20 × D, where D is the diameter of cable; the minimum bending radius of a fiber cable under no load is 15 × D.

Free-space point-to-point optical links can be implemented using infrared laser light, although low-data-rate ommunication over short distances is possible using LEDs. Infrared Data Association (IrDA) technology is a very simple form of free-space optical communications. On the communications side the FSO technology is considered as a part of the optical wireless communications applications. Free-space optics can be used for communications between spacecraft

Commercial products

In 2008, MRV Communications introduced a free-space optics (FSO)-based system with a data rate of 10 Gbit/s initially claiming a distance of 2 km at high availability.[6] This equipment is no longer available; before end-of-life, the product's useful distance was changed down to 350 m.[7]

In 2013, the company MOSTCOM started to serially produce a new wireless communication system[8] that also had a data rate of 10 Gbit/s as well as an improved range of up to 2.5 km, but to get to 99.99% uptime the designers used an RF hybrid solution, meaning the data rate drops to extremely low levels during atmospheric disturbances (typically down to 10 Mbit/s). In April 2014, the company with Scientific and Technological Centre "Fiord" demonstrated the transmission speed 30 Gbit/s under "laboratory conditions".

LightPointe offers many similar hybrid solutions to MOSTCOM's offering.[9]

Useful distances

The reliability of FSO units has always been a problem for commercial telecommunications. Consistently, studies find too many dropped packets and signal errors over small ranges (400 to 500 meters). This is from both independent studies, such as in the Czech republic,[10] as well as formal internal nationwide studies, such as one conducted by MRV FSO staff.[11] Military based studies consistently produce longer estimates for reliability, projecting the maximum range for terrestrial links is of the order of 2 to 3 km (1.2 to 1.9 mi).[12] All studies agree the stability and quality of the link is highly dependent on atmospheric factors such as rain, fog, dust and heat.
