Key Design Features
- CCP Wet-Mate Design: Cable-to-cable plug configuration enables field mating underwater at rated depth without draining or pressurizing housing — compatible with BCR bulkhead counterparts.
- Ultra-Deep Rating: Qualified to 8,000 m / 800 Bar mated pressure — suitable for full ocean-depth scientific and defence deployments.
- SM & MM Fibre Compatibility: Accepts single-mode (9/125 µm) or multimode (50/125 µm, 62.5/125 µm) fibres; factory-terminated with precision ferrules for <0.5 dB insertion loss.
- Low Insertion Loss: <0.5 dB typical per channel; return loss >40 dB — maintains signal integrity over multi-kilometre fibre runs.
- >500 Wet-Mate Cycles: Chloroprene rubber wipers and precision alignment bushings sustain repeated in-situ mating without optical performance degradation.
- Corrosion-Resistant Materials: Chloroprene rubber over-mould with titanium, 316 SS, or anodised aluminium options; gold-plated electrical contacts resist seawater corrosion for the design service life.
- Locking Sleeve Security: POM or stainless steel locking sleeves (MANDATORY before deployment) prevent accidental de-mating under ROV cable tension or sea-state vibration.
- Polyurethane (PUR) Cable Over-Mould: Factory-terminated PUR cable jacket provides flexible, kink-resistant strain relief rated for continuous dynamic service.
- Custom Configuration: Available with customer-specified cable lengths, fibre types, contact plating, and body material; pressure testing certificates available per unit.

Why Choose the FOCCCP-4F-8K Fibre Optic Connector?
Certified Ultra-Deep Performance
The FOCCCP-4F-8K is pressure-rated to 800 Bar (8,000 m depth), exceeding the requirements of most working-class ROV and scientific AUV systems. Every connector is hydro-tested before shipment, with pressure certificates available on request for programme QA compliance.
Factory-Terminated for Guaranteed Optical Performance
Fibre termination is performed in a controlled factory environment using precision ceramic or zirconia ferrules and automated polishing equipment, delivering insertion loss <0.5 dB and return loss >40 dB — performance levels that field termination cannot reliably achieve in offshore environments.
Wet-Mate Durability Over 500 Cycles
Chloroprene rubber wipers sweep the optical face clean during mating, while precision guide pins ensure repeatable fibre alignment. The connector is rated for >500 wet-mate cycles without measurable insertion loss increase — critical for ROV tooling systems requiring frequent connect/disconnect under water.
Compact All-Optical Design
The pure optical design avoids electromagnetic interference (EMI) that limits copper-based data links in high-noise environments such as thruster-heavy ROV systems and power distribution umbilicals. Optical transmission is immune to EMI and supports bandwidth-intensive payloads including 4K video and high-resolution sonar.
Tailored to Your System Requirements
RV Power Group manufactures the FOCCCP-4F-8K to order with customer-specified fibre type (SM/MM/PM), cable OD, body material (titanium, SS, anodised Al), contact count (for hybrid variants), and cable length. IEC 60793 and IEC 61300 test reports are available for quality-critical programmes.

| Hybrid power | Select hybrid (2 power contacts) when you need simultaneous power and data — eliminates a second cable penetration through the tether or housing |
| Locking sleeve | Always install POM or SS locking sleeve before deployment; retain for re-mating cycles |
| Custom requirements | Contact [email protected] for non-standard fibre types (PM, bend-insensitive), non-standard body materials, or batch pressure testing |
Frequently Asked Questions
Q: What is the difference between a CCP and BCR connector?
A: CCP (Cable-to-Cable Plug) is the wet-mate cable-terminated plug that connects underwater. BCR (Bulkhead Connector) is a panel-mounted feedthrough for dry-box or instrument-housing integration — the CCP cable plug mates into the BCR bulkhead from the wet side.
Q: What fibre types are supported?
A: Standard options are single-mode 9/125 µm (OS1/OS2) and multimode 50/125 µm or 62.5/125 µm (OM2–OM4). Polarisation-maintaining (PM) and bend-insensitive fibres are available on request.
Q: What data rate can the optical link support?
A: Connector insertion loss (<0.5 dB) is compatible with 10 Gbit/s single-mode links and 1 Gbit/s multimode links over typical subsea tether lengths. Actual data rate depends on total system loss budget and transceiver characteristics.
Q: How many times can the connector be mated underwater?
A: The FOCCCP-4F-8K is rated for >500 wet-mate cycles. Chloroprene wipers protect the optical face during mating; inspect and clean faces per the maintenance schedule every 50 cycles or annually.
Q: What is the rated depth and mated pressure?
A: The FOCCCP-4F-8K is rated to 8,000 m depth / 800 Bar mated pressure (11600 psi). Hydrostatic pressure certificates are available per unit on request.
Q: Is the connector rated for open-face (unmated) pressure exposure?
A: No — unlike electrical SubConn® connectors, the optical face must be protected by a dust/moisture cap when unmated. Do not expose the bare optical ferrule to seawater pressure without the mating counterpart or protective cap installed.
Q: What cleaning procedure is required before mating?
A: Inspect both optical faces with a fibre scope before each mating cycle. Clean with a dry, lint-free ferrule cleaner (e.g., Cletop stick) — do not use alcohol wipes offshore unless fully dried. Install locking sleeve after mating.
Q: Can I specify the cable length and type?
A: Yes. The FOCCCP-4F-8K is factory-terminated to order with customer-specified PUR cable length, OD, and fibre type. Minimum order quantity and lead times apply — contact [email protected] for a quotation.
Q: Are pressure test certificates available?
A: Yes. Certified hydrostatic pressure testing to the rated depth is available on a per-unit basis and is recommended for programme-critical applications. Certificates reference the tested pressure, date, and connector serial number.
Q: Is the connector compatible with fibre-optic rotary joints (FORJs)?
A: The FOCCCP-4F-8K can be terminated to any single-mode or multimode fibre that feeds into a FORJ on a winch drum — standard SC/FC pigtail options available on request.
Q: Can I connect two CCP connectors together?
A: No — a CCP plug always mates with a BCR bulkhead counterpart. Two CCP connectors require an in-line BCR-BCR barrel adapter (available separately).
Installation, Mating & Maintenance Guidelines
Pre-Deployment Inspection
Before every deployment: (1) Inspect optical faces with a fibre microscope — reject any connector with scratches crossing the core region. (2) Clean ferrule faces with a dry Cletop or equivalent tool. (3) Inspect chloroprene wiper rings for cuts or deformation. (4) Verify O-rings are lightly greased with silicone grease. (5) Confirm locking sleeve is fully engaged after mating — listen/feel for the positive click. Never deploy without the locking sleeve.
Mating Procedure
(1) Remove protective caps from both CCP and BCR (or both CCP faces) immediately before mating — minimise air exposure time. (2) Align guide pins and insert CCP into BCR with a smooth single-stroke push — do not rotate the optical body during insertion. (3) Slide locking sleeve forward until locked. (4) Perform a quick-check optical power measurement if an OTDR or light source is accessible. (5) Verify electrical continuity on hybrid connectors before deployment.
Storage & Long-Term Maintenance
Store unmated connectors with protective caps installed; keep in a clean, dry environment. Inspect and clean optical faces every 50 cycles or at least annually. Replace chloroprene wiper O-rings every 2–3 years or if visible cracking appears. Do not use abrasive cleaners on the chloroprene body. Return to RV Power Group for factory refurbishment if insertion loss exceeds 1.0 dB on any channel.
