The HYBBCR-2F2P is a subsea-rated Hybrid Opto-Electric BCR Bulkhead Connector designed for depths to 6,000 m (600 Bar / 8700 psi). Featuring 2-Core Fibre Optic optical channel(s) with single-mode (SM) or multimode (MM) compatibility and a chloroprene rubber over-moulded body, this connector delivers ultra-low insertion loss, <0.5 dB typical, for critical subsea sensing, imaging, and data-link applications. Combined with 2 power contacts rated at 600 V / 10 A per contact, this hybrid connector delivers simultaneous high-bandwidth optical data and electrical power in a single robust body — eliminating the need for separate cable penetrations. The connector is available as BCR (Bulkhead Connector for dry-box integration), with gold-plated electrical contacts (where fitted), titanium or stainless steel hardware, and POM or SS locking sleeves to ensure secure retention in dynamic sea states.

Why Choose the HYBBCR-2F2P Hybrid Connector?
Certified Ultra-Deep Performance
The HYBBCR-2F2P is pressure-rated to 600 Bar (6,000 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.
Hybrid Single-Cable Solution
By integrating optical fibres and power contacts in a single connector body, the HYBBCR-2F2P eliminates the need for parallel cable runs and multiple penetrations — reducing drag on tethers, simplifying ROV panel layout, and improving overall system reliability.
Tailored to Your System Requirements
RV Power Group manufactures the HYBBCR-2F2P 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.

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 HYBBCR-2F2P 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 HYBBCR-2F2P is rated to 6,000 m depth / 600 Bar mated pressure (8700 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 HYBBCR-2F2P 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: Can the hybrid connector carry both power and optical signals simultaneously?
A: Yes. The HYBBCR-2F2P routes optical fibre channels and 2 electrical power contacts (600 V / 10 A each) through a single body with full optical-electrical isolation. There is no crosstalk between the optical and electrical sections.
Q: What is the maximum electrical current for the hybrid version?
A: Each power contact is rated 10 A, giving a maximum of 20 A total per connector. For higher current requirements, contact us for custom multi-contact power designs.
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.
