MTP®/MPO to LC Harness
Pre-Terminated MTP®/MPO to LC Fanout Harness for Cassettes, Racks and Backbone Links
An MTP®/MPO harness breaks one multi-fiber MPO connector out into individual LC connectors, so a parallel-optic trunk can connect to duplex equipment ports, patch panels or cassette modules. EXW builds three harness constructions: 0.9 mm fibers for use inside cassette modules, 2.0 mm round-cable legs for patching from the trunk to the rack, and multi-fiber trunk harnesses for backbone runs. Polarity is specified at order (Type A, B or C), and every harness is factory-terminated and tested before shipment.
Specifications
- MTP®/MPO connector: 8, 12, 16, 24 or 32 fibers.
- Other end: LC connectors, simplex or duplex.
- Three constructions: 0.9 mm fibers for cassette modules, 2.0 mm round-cable legs for patching, and multi-fiber trunk harnesses for backbone runs.
- Fiber types: OM3, OM4 and OM5 bend-insensitive multimode (BIMMF), and OS2 G.657.A single mode.
- Polarity: Type A, Type B, Type C, or customized, as defined in ANSI/TIA-568.3-E.
- MTP®/MPO connector options: US Conec MTP® or MPO-compatible; male (with pins) or female (unpinned).
- Performance grades: Standard Loss and Low Loss; see the insertion loss and return loss tables.
- Breakout leg length, overall length and pulling eye (trunk harness) available on request.
Mechanical Characteristics
- Reliable high-density interconnection for: transitions from MTP®/MPO trunk cabling to duplex equipment ports, patch panels and cassette modules in data center main, horizontal and zone distribution areas; telecommunications networks and broadband/CATV networks.
Note
- Fiber Compatibility: OM3, OM4, OM5 (BIMMF) and OS2 G.657.A
Which Harness Construction Do You Need?
All three harness constructions break an MTP®/MPO connector out into LC connectors. They differ in the cable on the breakout side and where the harness is installed.
| Construction | Breakout side | Typical installation |
|---|---|---|
| Cassette harness | 0.9 mm fibers to simplex LC connectors | Inside plug-and-play fiber cassette modules |
| Patch harness | 2.0 mm round-cable legs to simplex or duplex LC connectors | From the trunk to the rack or equipment |
| Trunk harness | Multi-fiber cable fanned out at one end; pulling eye on request | Backbone runs with MPO at one end and LC at the other |
Connecting to a parallel transceiver? ANSI/TIA-568.3-E Annex C describes using unpinned (female) MPO connectors on the cords that plug into equipment, because currently known parallel transceiver receptacles are pinned. Specify the connector gender at order.
MTP®/MPO Insertion Loss and Return Loss Grades
Maximum insertion loss per MTP®/MPO connector mating, with the minimum return loss for each grade.
| Grade / Fiber Type | Standard Loss | Low Loss |
|---|---|---|
| Insertion loss — BIMMF OM3 / OM4 / OM5 (Multimode) | ≤ 0.50 dB | ≤ 0.35 dB |
| Insertion loss — SM OS2 G.657.A (Single-mode) | ≤ 0.75 dB | ≤ 0.35 dB |
| Return loss — BIMMF OM3 / OM4 / OM5 (Multimode) | ≥ 20 dB | ≥ 20 dB |
| Return loss — SM OS2 G.657.A (Single-mode) | ≥ 60 dB | ≥ 60 dB |
LC Insertion Loss and Return Loss Grades
For the LC connectors on the breakout side of the harness.
| Grade / Fiber Type | Standard Loss | Low Loss |
|---|---|---|
| Insertion loss — BIMMF OM3 / OM4 / OM5 (Multimode) | ≤ 0.30 dB | ≤ 0.15 dB |
| Insertion loss — SM OS2 G.657.A (Single-mode) | ≤ 0.20 dB | ≤ 0.15 dB |
| Return loss — BIMMF OM3 / OM4 / OM5 (Multimode) | ≥ 35 dB | ≥ 35 dB |
| Return loss — SM OS2 G.657.A (Single-mode) | ≥ 55 dB | ≥ 55 dB |
These are EXW product grades. ANSI/TIA-568.3-E Annex A sets a maximum of 0.75 dB insertion loss per mated connector pair, applying the same limit to MPO array connectors and single-fiber connectors.
How to Order an MTP®/MPO to LC Harness
Each harness is built to order. Specify the following when requesting a quotation so the assembly arrives ready to install without field adaptation.
| Step | Parameter | Options |
|---|---|---|
| 1 | MTP®/MPO fiber count | 8 / 12 / 16 / 24 / 32 |
| 2 | Fiber mode | Single mode: OS2 G.657.A (yellow). Multimode: OM3 (aqua), OM4 (violet), OM5 (lime green). |
| 3 | Construction | Cassette harness (0.9 mm fibers) / Patch harness (2.0 mm legs) / Trunk harness (multi-fiber cable) |
| 4 | LC connectors | Simplex or duplex |
| 5 | MTP®/MPO connector | US Conec MTP® or MPO-compatible; male (with pins) or female (unpinned) |
| 6 | Polarity | Type A / Type B / Type C / Customized |
| 7 | Performance grade and length | Standard Loss / Low Loss; breakout leg length and overall length in feet or meters |
