Camera Data Interfaces

Emergent Vision Technologies cameras have one of the following data interfaces, depending on the model’s camera family:

• 10GigE, 5GigE, 2.5GigE, and 1GigE RJ45
• 10GigE SFP+
• 25GigE SFP28
• 100GigE QSFP28

Camera data interface ports

This section describes the data interface ports on Emergent cameras.

RJ45 data interfaces

The RJ45 Ethernet port used in Emergent’s Eros, HT, and Pace LT cameras is a standard port for 1 Gb, 2.5 Gb, 5 Gb and 10 Gb Ethernet applications.

‍Note: Eros cameras, but not HT and Pace LT cameras, support power-over-Ethernet (PoE). So you can power Eros cameras through either the RJ45 port or the GPIO port.

SFP+ data interfaces

The SFP+ port used in Emergent’s HR and Pace LR cameras is a standard port for 10 Gb Ethernet applications. SFP+ stands for “enhanced small form-factor pluggable.” SFP+ has significant advantages over other Ethernet cabling options, including a variety of cabling options including Direct Attach, which is a copper-base solution for reliable transmission up to 10m, and Fiber Based Transceiver solutions for significantly longer transmission distances limited only by the available fiber transceiver technologies.

SFP28 data interfaces

The SFP28 port used in Emergent’s Bolt and Accel cameras is a standard port for 25 Gb Ethernet applications. SFP28 stands for “small form-factor pluggable 28”, which has a maximum data rate of 28 Gbps. SFP+ has some significant advantages over other Ethernet cabling options including a variety of cabling options including Direct Attach, which is a copper-base solution for reliable transmission up to 10m, and Fiber Based Transceiver solutions for significantly longer transmission distances limited only by the available fiber transceiver technologies.

QSFP28 data interfaces

The QSFP28 port used in Emergent’s Zenith and Pinnacle cameras, is designed for 100 Gigabit Ethernet applications. QSFP28 stands for "quad small form-factor pluggable 28”, which has a maximum data rate of 28 Gbps in each of its four channels. QSFP28 supports high-speed data transmission, making it suitable for demanding applications that require substantial bandwidth.

Connect and disconnect data-interface cables

Before connecting a cable, confirm that the cable, transceiver, and ports support the required interface and link rate. See Network Cables and Optical Transceivers for component-selection guidance.

Perform the applicable procedure at each endpoint. Align connectors carefully and insert them straight into the port. Do not force a connector. Before disconnecting a cable or transceiver, identify its release control. If it does not release with light hand pressure, stop and confirm how its mechanism operates.

Connect and disconnect an RJ45 cable

An RJ45 plug has a plastic locking tab. Some plugs have a snagless guard or boot over the tab.

To connect an RJ45 cable:

1. Align the keyed RJ45 plug with the port.
2. Hold the plug body and push it straight into the port until it is fully seated and latched.
3. Connect the other end to the corresponding RJ45 port.

To disconnect an RJ45 cable:

1. Hold the plug body.
2. Press the locking tab toward the plug body. If the plug has a snagless guard, press the guard where it operates the locking tab.
3. Keep the tab depressed and pull the plug straight out of the port. Do not pull on the cable.

[Image placeholder: Add a close-up of the RJ45 plug used with Emergent Vision cameras. Label the locking tab and any snagless guard. Use an arrow to show the confirmed direction in which the tab is pressed.]

Connect and disconnect a DAC or AOC assembly

Direct-attach copper (DAC) and active optical cable (AOC) assemblies have permanently attached pluggable ends. Depending on the product, the end may use a pull tab, pull handle, or another release mechanism.

To connect a DAC or AOC assembly:

1. Confirm that the assembly and both ports support the required interface and link rate.
2. Align one cable end with the port.
3. Hold the connector housing and push it straight into the port until it is fully seated and latched.
4. Connect the other end to the corresponding port.

To disconnect a DAC or AOC assembly:

1. Identify the release control fitted to the cable end.
2. Operate the release control in its specified direction to disengage the latch.
3. While the latch is disengaged, hold the connector housing or fitted pull handle and pull the connector straight out of the port. Do not pull on the cable itself.
4. Repeat the procedure at the other endpoint.

Release mechanisms differ between products. Do not assume that an SFP+, SFP28, or QSFP28 cable end uses the same release action as another cable with the same form factor.

[Image placeholder: Add confirmed close-ups of the release mechanisms fitted to supported SFP+, SFP28, and QSFP28 DAC and AOC assemblies. Label each pull tab or handle and show its direction of movement.]

Install and remove an optical transceiver and LC fibre cable

A modular fibre connection uses a separate optical transceiver at each endpoint and a fibre-optic cable between them. The latch on the LC plug releases the fibre cable from the transceiver. The transceiver’s release mechanism releases the transceiver from the device port.

To install a transceiver and connect an LC fibre cable:

1. Confirm that the transceiver, fibre type, connectors, and host port support the required connection.
2. With the fibre cable disconnected, align the transceiver with the port.
3. Hold the transceiver housing and push it straight into the port until it is fully seated and latched.
4. Remove the protective caps from the transceiver and LC plug immediately before making the connection. Do not touch the exposed optical surfaces.
5. Align the LC plug with the transceiver receptacle.
6. Hold the LC plug body and push it straight into the receptacle until it is fully seated and latched.
7. Install the corresponding transceiver and connect the other end of the fibre cable at the other endpoint.

To disconnect the fibre cable and remove the transceiver:

1. Hold the LC plug body and operate its release latch.
2. Pull the LC plug straight out of the transceiver. Do not pull on the fibre cable.
3. Fit protective caps to the disconnected optical components.
4. Identify the transceiver’s release mechanism, such as a hinged bail or pull handle.
5. Operate the release mechanism in its specified direction to disengage the transceiver.
6. Hold the transceiver housing or fitted handle and pull the transceiver straight out of the port.

Do not attempt to remove the transceiver by pulling on the connected fibre cable. Release the LC plug before operating the transceiver’s release mechanism.
