Single mode
Multimode
Dual mode (mixed single and multimode)
Ferrules
Suitable for 126μm and 125μm
900μm single fiber or mini breakout cable
Special ferrules for 2mm single cable optional
Wavelength: 850-1300nm, 1310-1550nm
vibration
According to EIA/TIA-455-11: Sinusoidal test, Condition III (at 40 g), and random test, Condition IV (Category C), for a duration of 1.5 hours.
Shock
According to EIA/TIA-455-14, Test Condition A
Locking mechanism
Hermaphroditic thread
all shell styles can be cross mated
enables cable extensions for different distances
technology
Beam-expanding lenses
less susceptible to dirt and dust
easy to clean
thus less impairment of optical performance
Norm / Standard
GTB / GMTB
The GTB series is compatible with MIL-PRF-83526 and VG95319-100, -101, -102, or VG96977, and is the commercial equivalent. However, in addition to the versions described in the standard, GTB connectors offer an additional selection of shell styles and materials, insert
arrangements up to 12 channels, and backshells for BRUmil or BRUtough cables.
VG96977 Approval in progress
