Overview

A transceiver module converts electrical data signals to laser light, which is then transmitted over an optical fiber. It can transmit optical signals over long distance with low signal loss. H3C devices support many types of transceiver modules in different specifications.

H3C fiber network cables are Active Optical Cables (AOCs) terminated with transceiver modules. H3C copper network cables include Active Copper Cables (ACCs) and Direct Attach Cables (DACs), which are coaxial cables terminated with transceiver modules. Fiber and copper network cables are collectively referred to as "network cable" in this document.

H3C devices support the following transceiver modules and network cables:

·     Transceiver modules—QSFP-DD, QSFP28, CFP, CFP2, CXP, QSFP+, SFP28, SFP+, XFP, and SFP transceiver modules.

·     Fiber network cables—QSFP-DD, QSFP28, CXP, QSFP+, SFP28, and SFP+ fiber network cables.

·     Copper network cables—QSFP-DD, QSFP28, QSFP28 to SFP28, QSFP+, QSFP+ to SFP+, SFP28, SFP+, CX4, and GE SFP copper network cables.

 

	NOTE: ·     The available transceiver modules and network cables vary by device model. For transceiver modules and network cables available for an H3C device, see the installation guide for the product. ·     H3C transceiver modules and network cables are subject to change over time. For the most recent list of H3C transceiver modules and network cables, contact H3C Support or marketing staff

 

 

Preparing for installation

CAUTION: ·     To avoid ESD damage to transceiver modules, network cables, or electronic components on the device, always wear an ESD wrist strap while handling transceiver module or network cables. In addition, make sure anti-ESD measures (such as dust prevention and temperature and humidity maintenance) are in place at the installation site. ·     If ESD gloves are available, wear the gloves first and then the ESD wrist strap and make sure the strap makes good contact with the glove.

 

To attach an ESD wrist strap:

1.     Wear the strap on your wrist and fasten it securely. Make sure the strap makes good skin contact.

2.     Ground the strap reliably.

¡     If the device has an ESD jack, connect the grounding terminal of the strap to the ESD jack, as shown in Figure 1.

¡     If the device does not have an ESD jack, clip the grounding terminal of the strap to a rack post as shown in Figure 2, or take other measures to ground the strap reliably.

Installing and removing a transceiver module

	WARNING! Do not stare into any open apertures of operating transceiver modules or optical fiber connectors. The laser light emitted from these apertures might hurt your eyes.

 

	CAUTION: ·     During the installation or removal process, be careful not to touch the golden plating on the transceiver module. ·     Before inserting a transceiver module into a port, make sure the transceiver module aligns with the port correctly.

 

H3C transceiver modules are available in three types:

·     Bale-clasp latch transceiver modules—Include CFP2, QSFP+, SFP28, SFP+, XFP, and SFP transceiver modules. For the installation and removal procedure, see "Installing and removing a bail latch transceiver module."

·     Pull latch transceiver modules—Include QSFP-DD, QSFP28, CXP, and QSFP+ transceiver modules. For the installation and removal procedure, see "Installing and removing a pull latch transceiver module."

·     Transceiver modules with captive screws—Include CFP transceiver modules. For the installation and removal procedure, see "Installing and removing a transceiver module with captive screws."

Installing and removing a bail latch transceiver module

This installation method is applicable to the CFP2, QSFP+, SFP28, SFP+, XFP, and SFP transceiver modules. The following procedure uses a QSFP+ transceiver module as an example.

Installation procedure

1.     Remove the dust plug from the target fiber port.

2.     As shown by callout 1 in Figure 3, close the bail latch upward to catch the knob on the top of the transceiver module.

3.     Grasp the transceiver module between your thumb and index finger and correctly orient it. Align it with the fiber port and push it gently into the port until you feel it snaps into place. See callout 2 in Figure 3.

Transceiver modules and fiber ports have disorientation rejection designs. If you cannot insert a transceiver module easily into a port, the orientation might be wrong. Remove and reorient the transceiver module.

In case of limited space, you can gently push against the front face of the transceiver module instead of the two sides.

4.     Grasping the fiber connector between your thumb and index finger, align it with the transceiver module optical bore and push it into the bore.

Transceiver module optical bores and fiber connectors have disorientation rejection designs. If you cannot insert a fiber connector easily into a transceiver module optical bore, the orientation might be wrong. Remove and reorient the connector.

5.     If you are not to install an optical fiber, insert a dust plug into the transceiver module bore.

 

	NOTE: The triangular pin on a transceiver module and the hole in a fiber port function together to prevent the module from disengaging from the port.

 

Removal procedure

1.     Remove the optical fiber from the transceiver module.

There is a latching mechanism between a fiber connector and transceiver module port to prevent connector disengagement. Release the latching mechanism before removing the optical fiber. To avoid damages, do not use excessive force.

2.     Pivot the bail latch down until it stops, as shown by callout 1 in Figure 4.

3.     Holding the bail latch, carefully pull the transceiver module straight out of the fiber port.

If you use force at an angle as shown in Figure 6, you can hardly pull the transceiver module out and the transceiver module or fiber port might be damaged. If you forcibly pull out of the transceiver module without pivoting the bail latch down, the triangular pin of the transceiver module and the fiber port might be damaged.

To avoid damaging the bail latch, use event force to pull the transceiver module out.
