TFOCA
GenX® is a deviation from the original TFOCA due to diminishing supply concerns of the biconic termini technology and the need for a change in the
technology resulting from the First Digitized Division (FDD) LAN design whose commercial fiber interfaces use standard 62.5/125 micron fiber versus the 50/125 micron fiber associated with TFOCA. Similar to the original TFOCA connector,
TFOCA
GenX is based on MIL-C-83526, dated 19 Aug 86, slash 1, 3, 6, with components and similarities to the original TFOCA (slash 13) and the MIL-ST connector which is based on MIL-C-83522.
The objective of this specification is to create fiber optics interconnect standards for hermaphroditic tactical deployable requirements to meet both present and future communication interconnect needs. This specification is intended to meet system requirements for both low speed
data to high-speed digital and analog bandwidth needs.
TFOCA GenX shall use standardized commercial 2.5mm ceramic ferrule technology to: 1) facilitates cost, 2) ensure present and future availability of technology 3) Provide long term logistical requirements. This specification establishes the optical, mechanical, environmental and functional requirements for the
TFOCA GenX connector series.
Three connector configurations
are available; 1) Multi Mode (4 Fiber 62.5/125), 2) Single Mode (4 Fiber 8.3/125), and 3) Hybrid (2 Fiber 62.5/125 & 2 fiber
9/125). All 3 configurations include a plug with dust cap and "D" mount receptacle with dust cap. Each terminated plug and receptacle shall be marked to identify the fiber configuration. Markings shall be as follows:
1)
4 Fiber Multi-Mode: No external markings.
4 Fiber Single-Mode: External marking of a yellow band readily visible on both
2)
hermaphroditic
plugs and receptacles mated or unmated.
3)
Hybrid, 2 EA Multi-mode and 2EA Single-mode: External marking of a light blue band
readily visible on both hermaphroditic plugs and receptacles mated or unmated.
