What are the common parameters of optical transceiver

 First, the center wavelength: unit nanometer (nm), currently there are three main types: 1) 850nm (MM, multi-mode, low cost but short transmission distance, generally only 500M can be transmitted); 2) 1310nm (SM, single mode, large loss during transmission but small dispersion, generally used for transmission within 40KM); 3) 1550nm (SM, single-mode, low loss but large dispersion during transmission, generally used for long-distance transmission above 40KM, and can directly transmit 120KM without relay at the farthest); Second, the transmission rate: refers to the number of bits (bits) of data transmitted per second, in bps. There are currently four commonly used: 155Mbps, 1.25Gbps, 2.5Gbps, 10Gbps, etc. Transmission rates are generally downward compatible, so 155M optical modules are also called FE (100M)  H3C SFP-XG-T  , and 1.25G optical modules are also known as GE (Gigabit) optical modules, which are the most used modules in optical transmission equipment. In addition, its transm

There are 8 measures to set up a 40G QSFP+ transceiver.

 The QSFP+ transceiver module is certainly a static-sensitive device. So, we always utilize an ESD wrist strap or similar individual grounding device when handling QSFP+ transceiver modules or getting into connection with system modules. Besides, the  Cisco QSFP-40G-LR4  module can have the bail-clasp latch or a pull-tab latch. In this text, installation procedures for both types of latches can be found. These 8 measures are as pursuing: Step one 1: Attach an ESD wrist strap to yourself and an adequately grounded stage on the chassis or the rack. Step two 2: Take away the QSFP+ transceiver module from its protective packaging. Step three 3: Check the label on the QSFP+ transceiver module body to verify that you have the right model for your network. Step 4: For optical QSFP+ transceivers, remove the optical bore dust plug and set it aside. Step 5: For transceivers equipped with a bail-clasp latch: a. Keep carefully the bail-clasp aligned in a vertical position. b. Align the QSFP+ trans

Why the temperature of the optical module will rise: May be the optical module selected correctly?

 Based on the operating temperature, optical modules can be split into commercial and commercial grades, among which commercial optical modules will be the hottest. But actually, different application conditions need to choose the optical module of the corresponding temperature level, otherwise it is simple to cause the temperature of the optical module to be abnormal and affect normal use. Just how to help make the right choice among common commercial and industrial optical modules? •Commercial-grade optical modules are suitable for indoor data center computer rooms-because the inner interconnection of the info center takes a relatively small operating temperature range for the optical modules (national policy stipulates that the indoor temperature of the computer room should be managed at 22±2°C); and the optical modules are reliable The performance requirements aren't high, for that reason, commercial-grade optical modules could be selected for indoor data center computer rooms.
