Is an adapter required for IDC connector mating?

No. IDC uses threaded metal coupling between male and female ends for direct mating. For panel feed-through, use the matching panel receptacle/socket.

What does IP68 mean for IDC assemblies?

IP68 sealing is achieved when the correct interface pair is fully mated and tightened. Unmated ports should be protected with dust caps.

Which builds are most common: IDC-to-IDC or IDC-to-LC/UPC fanout?

IDC-to-IDC is typical for FTTA CPRI outdoor jumpers. IDC-to-LC/UPC fanout is used for equipment-side patching to standard LC ports.

What fiber is recommended for this series page?

Default is OS2 singlemode G657A1 for better bend tolerance in cabinets and outdoor routing while maintaining OS2 performance.

How do I choose 2-core vs 4-core vs MT multi-core?

Select based on required channels and the equipment interface. 2-core and 4-core are common for CPRI links; MT is used for higher density applications.

What information is required to avoid wrong mating?

Confirm plug/socket style, keying/interface type, and pinout mapping. A photo or drawing of the existing port is recommended before bulk order.

Can IDC be used in power utility outdoor deployments?

Yes. IDC is used in harsh outdoor environments such as substations and monitoring/sensing links. Confirm jacket material and mechanical requirements for the site.

What jacket options are available?

Outdoor sections typically use PE/TPU depending on environment; indoor fanout sections commonly use LSZH. Specify your requirement in the RFQ.

How should I start before mass production?

Start with samples for fit/mating verification and confirm interface, keying, and pinout mapping, then lock the BOM for bulk production.

IDC Series IP68 Waterproof Fiber Connector (2C/4C/MT, OS2 G657A1) for FTTA CPRI

Name: IDC Outdoor Waterproof Fiber Connector (IP68 Ruggedized) – FTTA & Industrial
Brand: ABPTEL

Description

Highlights

Designed for FTTA CPRI jumpers and outdoor fiber links in power utilities (substations, sensing, monitoring)
Threaded metal coupling (male/female) enables quick field mating without an in-line adapter
IP68 sealing concept (when fully mated and tightened), factory pre-terminated OS2 G657A1, optional test records

Overview

ABPTEL IDC Series are waterproof fiber optic connectors engineered for outdoor deployment where stable mating, dust protection, and fast installation matter. The connector pair locks by a metal screw-thread coupling between male and female ends, reducing the need for on-site splicing and minimizing “wrong fit” risk when interface, keying, and pinout are confirmed upfront. As a series page, IDC supports 2-core, 4-core and MT multi-core options, with OS2 G657A1 as the default fiber. Typical assemblies include IDC↔IDC for FTTA CPRI links and IDC↔LC/UPC fanout for equipment-side patching. Target sealing level is IP68 when properly mated.

Typical Builds

1) IDC ↔ IDC (Outdoor CPRI Jumper)

Choose Your Core Count

IDC 2-Core: standard dual-fiber link; common for CPRI-style connections and simple outdoor links
IDC 4-Core: higher channel count in one connector; useful when you need 2 fiber pairs or redundancy
IDC MT Multi-Core: high density multi-fiber interface; recommended when space/port density is the priority (confirm MT polarity/pinout)

Structure & How It Works

IDC outdoor reliability depends on correct mating interface and tightening:
1) Alignment & keying: the interface aligns by keying; confirm A/B style and key position before order
2) Threaded coupling: metal screw-thread locks the connector pair against vibration and pull
3) Sealing zone: gasket/O-ring area is compressed during tightening to achieve water/dust sealing (IP68 when properly mated)
4) Dust cap strategy: caps protect unmated ports from contamination in field deployment
5) Factory termination: assemblies are pre-terminated to reduce field splicing risk and keep performance consistent
Tip: send an interface photo or drawing for confirmation of plug/socket style, keying, and pinout mapping.

Compatibility

Compatible with IDC-interface FTTA/power outdoor fiber systems used in:

Ericsson
Nokia
Huawei
ZTE

Important: Compatibility is defined by the exact mating interface (plug/socket style), keying, and pinout. Share your port reference or drawing for final confirmation.

The IDC Standard: Built for Extremes

The ABPTEL IDC Waterproof Connector is engineered for scenarios where standard fiber connectors fail. Featuring a high-grade Anti-Corrosion Metal / Polymer Body and a secure locking mechanism, the IDC series ensures signal continuity in high-vibration and high-humidity environments.

IP68 Protection: Withstands continuous immersion.
Secure Locking: Prevents accidental disconnection under tension.
Blind Mating Capable: Keyed design for fast field installation.

FAQ (Engineering-Oriented)

1) Is IP68 guaranteed for all IDC assemblies?
IP68 applies when the connector is the correct interface pair and is fully mated and tightened. Unmated ports should use dust caps.

2) Do IDC connectors need an in-line adapter?
For cable-to-cable mating, IDC uses male/female coupling directly—no in-line adapter is needed. For panel feed-through, use the matching panel receptacle/socket.

3) IDC↔IDC vs IDC↔LC/UPC fanout—how to choose?
IDC↔IDC is best for outdoor CPRI jumpers (cabinet-to-RRU). IDC↔LC/UPC fanout is best when the equipment side uses standard LC patching (ODF/switch).

4) Why OS2 G657A1 as default?
G657A1 improves bend tolerance, which is practical for tight routing in cabinets and outdoor boxes while keeping singlemode OS2 performance.

5) 2-core vs 4-core—what’s the practical difference?
2-core is a standard dual-fiber link. 4-core provides two fiber pairs (more channels or redundancy) in one assembly—useful when ports are limited.

6) What must be confirmed to avoid “cannot mate”?
Confirm plug/socket style, A/B interface, keying position, and pinout mapping. A photo of the existing port is often enough for a fit check.

7) Can you make IDC to LC/UPC duplex/quad fanout?
Yes. Specify duplex or quad, fanout leg length, cable OD (3.0 mm typical), and LSZH requirement for indoor sections.

8) Do you support panel receptacles (square/hex mounting)?
Yes. Provide panel cutout preference (square or hex style) and the mounting dimensions from your drawing.

9) Can IDC be used in power utility outdoor environments?
Yes. IDC is commonly used where water/dust and vibration exist (substation yards, outdoor cabinets, sensing/monitoring links). Confirm jacket material and mechanical needs.

10) What’s the safest way to start before bulk order?
Start with samples for mating/fit and routing verification, then lock the interface, keying, and pinout mapping before mass production.
