The 3M 2178 Fiber Optic Splice Case family has always
given you great protection for fiber optic connections. Now,
the addition of 3M 2178-L/S Series Fiber Optic Splice
Cases adds more capabilities to the family.
More chemical-resistant
With the new addition you get all the features of the popular
2178 splice case. Plus, the 2178-L/S series consists of a
tough chemical-resistant material and a new gasket seal that
make this the ideal splice case for outside plant, underg r o u n d ,
aerial, pedestal and direct buried applications.
Meets your changing network needs
The 2178-L/S series is designed with larger and smaller
interchangeable closure halves so you can select the size
case that meets your needs today, but with the flexibility to
expand for the future. Cable ports and space for trays can be
added at reentry with the 3M 2181-L/S Cable Addition Kit.
The ease of installation is unsurpassed, requiring no
special tools or complicated training procedures. The
closures are easily reenterable to allow access to the splices.
The ultimate protection for fiber optic
connections
The 2178-L/S series feature a tough, rigid non-filled case,
tested under real-world conditions, that stands up to even the
most severe conditions of moisture, vibration and extreme
temperatures. The closure will withstand up to 200 pounds
(90.7 kg) compression.
Design improvements to the 2178-L/S series include
changes to improve the cable strain relief and a movable tray
support. The closures hold cables of varying sizes and provide
flexibility to add ports on both ends with the cable addition
kit. The 2178-L/S series splice cases can be used with the
3 M 2522 or 2523 Small Fiber Splice Organizer Trays or the
3 M 2524 Fibrlok Small Fiber Splice Organizer Tray and
most other commercially available trays..
