MINI-OTE 300 OPTICAL TERMINAL ENCLOSURE
1 General product information
CommScope’s Mini-OTE 300 closure is a gel sealed ber optic terminating enclosure designed for the telecom outside
plant network. The closure is available in 2, 4, 6, 8 and 12 port versions with full-size or mini-size DLX® hardened adapters
with options for factory installed splitter or CWDM. The closure has a maximum splice capacity of 40 splices. It is suitable
for deployment in aerial, pole, pedestal, and below grade applications. The Mini-OTE 300 allows for both in line and butt
congurations with 5 ports accepting standard at drop up to ½” diameter cable for multiple combinations of feeder and
drop cables. Sealing is achieved by spring loaded gel technology, resulting in extremely convenient re-entry and resealing.
1.1 Cable types
The Mini-OTE 300 is designed for standard at drop, with or without toning wire, and loose buer tube and central core tube
up to ½” diameter cable. Provisions are provided for shielded cable grounding. Fiber types include single ber 250 micron,
at matrix ribbon, and rollable ribbon ber.
For cables that are ½” diameter it may be necessary to remove the plastic ring-strip that is located above the lower gel block,
such as 96F.
