It helps use an installed 12-fiber MTP® backbone with equipment or optical interfaces that use 8-fiber connectivity. In common 2×MTP12-to-3×MTP8 and 4×MTP12-to-6×MTP8 configurations, the harness maps 24 or 48 backbone fibers into 8-fiber interfaces, supporting efficient use of the existing fiber plant.

Engineering. Technology. Experience.
The Fibernet datasheet positions MTP® bundle and fanout products for high-density backplane and PCB applications in data and telecommunications systems. The product family is also presented for data centers, high-density environments, storage area networks, communications rooms and data communication networks.
The Fibernet datasheet identifies campus backbone, direct-burial and outdoor plant duct installations as applications. It also states that the armored trunk is dedicated for installation in outdoor duct systems.
Typical applications include data centers, high-density fiber environments, storage area networks (SANs), communications rooms and data communication networks. It is especially relevant when a Base-12 structured cabling backbone must interface with 8-fiber parallel-optics ports.

The harness is available in direct or crossed polarity and is designed for deployment using polarity management Method A. The ordering structure lists Standard Cross, Low Loss Cross, Standard Direct and Low Loss Direct options.
It depends on what the front side connects to. Use the MTP®-LC module when equipment takes duplex LC (10G/25G ports). Use the conversion module when migrating Base-12 trunks to Base-8 40G/100G ports with full fiber utilization. Use the adapter module when both sides are native MTP® – trunk-to-harness or trunk-to-trunk cross-connects.
Yes. The LC adapters include built-in shutters that block invisible laser light when no connector is inserted, protecting technicians’ eyes, and all connectors ship with dust caps to keep ferrules clean until patching.
Yes – that is a core purpose of the adapter module architecture. The backbone trunk terminates once at the adapter and stays untouched; migrating to 40G or 100G means changing the electronics and the cords in front of the module, while the same trunk cable keeps carrying the traffic.
Yes. The removable top cover and the STAR sliding-tray system give front, side and rear access to the module, so splices, pigtails and adapters can be inspected or reworked without removing adjacent modules – and individually numbered ports make identifying the right fiber straightforward.
Usually not – that is the point of the conversion module. Existing Base-12 trunks connect to the rear adapters as they are, and the front presents native Base-8 links for the new optics. The backbone stays; only the module layer and patch cords change.
The TAP is installed in the fiber path like any patching change, and from then on monitoring is non-intrusive: monitoring equipment can be connected, disconnected or changed on demand without interfering with live traffic, and monitored ports can be changed with minimum downtime.
Every LC fiber and port is individually tested for insertion loss (IL) and return loss (RL) and individually numbered for identification, and every connector’s ferrule geometry undergoes interferometer testing – so each module ships with verified optical performance.
By adapter color, at a glance: black/green adapters are single-mode, aqua adapters are OM3/OM4 multimode, and lime green adapters are OM5. In a frame mixing generations and fiber types, the color coding prevents mis-patching before it happens.
Every MTP® mating requires exactly one male connector (with guiding pins) and one female connector (without pins) – the pins seat into the opposite ferrule to align all fibers precisely. The adapter module supports this scheme with high-precision alignment, so planning simply requires that trunks and harnesses arrive with opposite genders at each adapter.
The module regroups fibers internally: two 12-fiber trunk connections (24 fibers) are rearranged into exactly three 8-fiber links (24 fibers). Nothing is left over – every trunk fiber reaches a port, which is a 33% saving in cabling volume compared to direct Base-12-to-Base-8 patching.
The front accepts 12 LC simplex or 6 LC duplex patch cords; the rear is a single MTP® adapter for the backbone trunk. LC adapters include internal shutters, ports follow the built-in labeling chart, and colored routing guides in each tray differentiate networks at a glance.
The module is ETL lab verified up to 100G Ethernet per IEEE 802.3ab-2010, and undergoes insertion loss and return loss (IL & RL) testing. LC connection insertion loss is 0.1 dB typical and 0.15 dB maximum.
Choose by what the front connects to: the MTP®-LC module when equipment takes duplex LC; the adapter module when both sides are native MTP®; and the conversion module when migrating Base-12 trunks to Base-8 40G/100G ports with 100% fiber utilization.
