Fiber Optic Splice Case 2178 Series
and Accessories
Fiber Optic Splice Closure
2178-XSB
As more fiber is deployed in the distribution network, more severe and compact environments
are encountered. The compact 2178-XSB closure features a rugged closure tested under
harsh, real-world conditions to stand up to even the most severe conditions of moisture,
vibration, and extreme temperatures.
The closure is the smallest member of the successful 2178 series of fiber optic splice closures.
The design concept, appearance, and method of installation are almost identical to the other
members of the 2178-series family, so no special tools or complicated training procedures are

(pedestal, handhole, and manhole) aerial (strand and pole mount) and wall
mount applications.
The compact size of the 2178-XSB closure (14.56" x 10.1" x 4.62") makes it ideal for
pedestal and handhole splicing, particularly for FTTP applications. Specifically
designed for butt splicing applications only, the closure has 3 cable entry ports (two
1.0" ports and one 1.4" ports). The multi-port grommets feature provides for simple,
flexible and future-proof drop or small diameter branch cable additions.
The 2178-XSB closure offers a flexible fiber management system for splicing and
storage with both stackable and hinged trays that accommodate various types of
splices (single or mass fusion and mechanical). The maximum single fusion and
mass fusion splice capacity for the 2178-XSB is 72 and 144 fibers, respectively.

FIBER OPTIC SPLICE CASE 2178-L/S SERIES
Fiber Optic Splice Case
2178-L/S Series
The 2178-L/S series is made of a tough chemical-resistant material and
a new gasket seal that make this the ideal splice case for outside plant,
underground, aerial and pedestal applications.
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 Cable Addition Kit
2181-L/S series.
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 2178-L/S series features 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 90.7 kg (200 lbs.) 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 various sizes and provides flexibility to add ports on both ends
with the cable addition kit. The 2178-L/S series splice cases can be used
with the 3M splice organizer trays 2522, 2523, 2527 and 2524 and most
other commercially available trays.
