Lightware HDMI20-OPTJ-RX90 Full 4K HDMI 2.0 Compatible Fiber Optical Extender - 91570001

Product Overview

The Lightware HDMI20-OPTJ-RX90 is the fiber receiver unit in Lightware's HDMI 2.0 fiber extender pair, designed to receive 4K HDMI 2.0 signals transported over fiber optic cable from a paired HDMI20-OPTJ-TX90 transmitter. The system supports transport distances of up to 300 meters over multi-mode fiber or up to 10 kilometers over single-mode fiber, delivering uncompressed 4K60 4:4:4 signals with full HDR, HDCP 2.2, and ARC support. It is the preferred solution for long-distance HDMI 2.0 extension in broadcast studios, large venue AV systems, and campus-wide signal distribution.

Product Description

The HDMI20-OPTJ-RX90 receives full-bandwidth HDMI 2.0 signals from a paired HDMI20-OPTJ-TX90 transmitter unit over a single fiber optic link. The unit supports the full HDMI 2.0 specification including 4K resolution at 60Hz with 4:4:4 color sampling, HDR10, HLG, and 18Gbps data rates, preserving complete signal integrity over long fiber runs without the bandwidth degradation inherent in copper cable at distance. HDCP 2.2 content protection is maintained end-to-end. The receiver outputs an HDMI 2.0 signal directly to any compatible display, projector, or downstream AV device. The fiber link is immune to electromagnetic interference, ground loops, and RF noise, making this system suitable for electrically challenging environments such as live event stages, outdoor venues, and industrial facilities. Both SFP fiber modules are included with the unit. The receiver is powered by an included 12V DC adapter and includes an RS-232 pass-through for control signal transport alongside the video signal over the same fiber infrastructure.

Key Features

• Full HDMI 2.0 Support — Receives 4K60 4:4:4 at 18Gbps, preserving complete HDMI 2.0 bandwidth over fiber
• Long-Reach Fiber Transport — Up to 300m via multi-mode fiber or up to 10km via single-mode fiber
• HDR and ARC Support — Passes HDR10, HLG metadata and Audio Return Channel signal without modification
• HDCP 2.2 Compliance — End-to-end HDCP 2.2 content protection maintained across the fiber link
• EMI Immunity — Fiber optic link eliminates ground loop and electromagnetic interference issues
• RS-232 Pass-Through — Transports serial control signals alongside video on the same fiber infrastructure
• Included SFP Modules — Fiber SFP transceivers included; no separate module purchase required
• Compact 1U Half-Rack — Standard rack-mount form factor for installation in AV equipment racks
• Pairs with HDMI20-OPTJ-TX90 — Receiver unit sold separately from paired transmitter (TX90) for flexible system configuration

Typical Applications

• Large venue installations requiring 4K signal transport from a head-end rack to distant display positions
• Broadcast studios running fiber backbone infrastructure for signal distribution
• Campus AV systems extending HDMI 2.0 between buildings over existing single-mode fiber plant
• Live event production where long HDMI runs and EMI immunity are required on stage or in outdoor environments
• Houses of worship distributing 4K content from a production booth to overflow screens at distances exceeding HDBaseT range
• Hospitality AV systems routing content from a central server room to guest rooms or function spaces via fiber

Frequently Asked Questions

Does this receiver work with any fiber transmitter, or must it be paired with the Lightware TX90?

The HDMI20-OPTJ-RX90 is designed to operate with the paired Lightware HDMI20-OPTJ-TX90 transmitter. SFP-based fiber extenders are not universally interoperable between brands due to signal encoding differences. Always use matched Lightware transmitter/receiver pairs for guaranteed performance.

What type of fiber cable is required — multi-mode or single-mode?

Both are supported with the appropriate SFP modules. Multi-mode fiber (OM3/OM4) supports distances up to 300 meters. Single-mode fiber (OS2) supports distances up to 10 kilometers. The included SFP modules should be confirmed at order time for the required fiber type.

Is 4K60 4:4:4 truly lossless over the fiber link?

Yes. The HDMI20-OPTJ system transports the HDMI 2.0 signal without compression or downsampling. The full 18Gbps bandwidth is preserved end-to-end, delivering a bit-for-bit identical signal at the receiver output compared to the transmitter input.

Does the fiber link carry audio as well as video?

Yes. The full HDMI 2.0 signal — including all embedded audio channels (up to 32 channels, Dolby Atmos, DTS:X) — is transported over the fiber link without any separation or external audio handling required.

Can this system be used in outdoor or industrial environments?

The fiber link itself is immune to EMI and does not carry electrical current between endpoints, making it suitable for outdoor and industrial environments where ground loops or interference would affect copper-based extenders. However, the terminal units require protection from moisture and temperature extremes outside the 0–40°C operating range.

Is a transmitter included with the purchase of this receiver?

No. The HDMI20-OPTJ-RX90 is the receiver unit only. The matching transmitter is the Lightware HDMI20-OPTJ-TX90, sold separately. Both units are available at Creation Networks.

Does the RS-232 pass-through require additional cabling separate from the fiber?

No. The RS-232 signal is transported over the same fiber link as the video, using the available data capacity of the fiber connection. No additional cable is required between the transmitter and receiver locations.
