Lantronix TN-QSFP-40G-xx User Guide Fiber Cable Physical Characteristics The fiber cable physical characteristics must meet or exceed IEEE 802.3ae specifications: • Single mode fiber (recommended): 9 μm • Multimode fiber (recommended): 62.5/125 μm • Multimode fiber (optional): 100/140, 85/140, 50/125 μm Warning: Visible and invisible laser radiation when open. DO NOT stare into laser beam or view directly with optical instruments. Failure to observe this warning could result in damage to your eyes or blindness. Connecting Fiber Cables To install the fiber cable, do the following: 1. Locate the appropriate fiber cable. 2. Install the cable as shown below. Removing a QSFP+ Module Caution: Be careful when removing the QSFP+ from a device. Some QSFP+ transceiver module temperatures may exceed 160°F (70°C) and be too hot to touch with bare hands. Note: Do not remove and replace the QSFP+ modules more often than necessary; excessive QSFP+ removing and replacing can shorten the useful life of the QSFP+. 1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis. 2. For future reattachment of fiber-optic cables, note which connector plug is send (TX) and which is receive (RX). 3. Remove the QSFP+ transceiver module: a. If the QSFP+ transceiver module has an actuator button latch, gently press the actuator button on the front of the QSFP+ transceiver module until it clicks and the latch mechanism releases the QSFP+ transceiver module from the socket connector. Grasp the actuator button between your thumb and index finger, and carefully pull the QSFP+ transceiver module straight out of the module slot. b. If the QSFP+ transceiver module has a bail clasp latch, pull the latch out and down to eject the QSFP+ transceiver module from the socket connector. If the bail clasp latch is obstructed and you cannot use your index finger to open it, use a small, flat-blade screwdriver or other long, narrow instrument to open the bail clasp latch. Grasp the QSFP+ transceiver module between your thumb and index finger, and carefully remove it from the socket. 4. Replace the Dust Plug. 5. Place the removed QSFP+ transceiver module in an antistatic bag or other protective package. 33684 Rev. D https://www.lantronix.com/ Page 9 of 16
