SFP Transceivers Options for Brocade 5100 Switch

Nowadays, many small and medium business and organizations such as local government, campus and some agencies etc., require fast and frequent access to database the files. A storage Area Network (SAN) with Fibre Channel (FC) switching technology (Figure 1) offers the speed and reliability for them. Brocade 5100 switch is an ideal Fibre Channel switch used for those organizations and can meet a variety of SAN environments.

Brief Introduction to Brocade 5100

The Brocade 5100 is a 1U Enterprise class Fibre Channel switch which combines 1, 2, 4, and 8 Gbps Fibre Channel technology in configurations of 24, 32 or up to 40 ports, getting an overall bandwidth of 320 Gbps. It is very flexible to users since it enables organizations to use 4Gbps SFPs today and upgrade to 8Gbps SFPs when required. By utilizing the sixth-generation ASIC (Application Specific Integrated Circuit) technology featuring five 8-port groups, it can reduce congestion and increase bandwidth. Because an ISL (Inter-Switch Link) trunk can supply up to 64 Gbps of balanced data throughput within these groups. In addition, enhanced Brocade ISL Trunking also utilizes ISLs more efficiently to preserve the number of usable switch ports. As shown in Figure 2, the port side of the Brocade 5100 includes the system status and power LED, console port, Ethernet port and LEDs, USB port, and FC ports and the corresponding port status LEDs. And the FC ports are numbered from left to right, in eight-port groups from 0 to 39, as illustrated in Figure 3.

Brocade 5100 ISL Trunking

As mentioned above, the Brocade 5100 can benefit from the trunking features which optimizes the use of bandwidth by allowing a group of ISL to merge into a single logical link. As we know, when ISL configured, there are certain issues like congestion. The congestion of Fibre channel links will eventually lead to performance issue and severe production impact. In this case, ISL trunking is an ideal solution to solve this issue.

As Figure 4 shown, when two switches get connected, there is a ISL link and the network traffic starts to flow through this link to the other switch. Without trunking, the congestion caused in the ISL which resulted in frames loss and bandwidth waste.

Using ISL trunking configurations, shown as Figure 5 (a), at 2Gbps speeds, the trunking delivers ISL throughput of up to 8 Gbps, avoiding the ISL congestion at the same time. In the same way, using 4 Gbps with 8 trunks can reach up to 32 Gbps, as Figure 5 (b) displayed.

Transceiver Options for Brocade 5100

Cable runs require transceivers at each end in SAN. In the SAN with Brocade Fibre Channel switches, Fibre Channel transceivers are used. Since the Brocade 5100 can support 1/2/4/8Gbps Fibre Channel, the transceiver options for Brocade 5100 are available in 1G, 2G, 4G and 8G Fibre Channel transceiver modules. Among these options, the transceivers with the data rate of 2, 4 and 8 Gbps are most commonly used in today’s Fibre Channel deployment. In addition, you can select either single-mode or multimode implementations by using the corresponding optics.

The following table shows the 2/4/8G transceiver modules that are available in infiberone.com. With strict coding technology and test assurance, these transceiver modules are highly compatible with Brocade and can achieve high performance in your Brocade 5100 switch in a cost-saving manner.

How to Install or Remove Fiber Optical SFP Transceiver Modules on Cisco Device

10g-sfp_1

The SFP (small form-factor pluggables) transceiver modules are hot-pluggable I/O devices that plug into module sockets. The transceiver connects the electrical circuitry of the module with the optical or copper network. Industrial SFP transceivers module are the key components in today’s transmission network. Thus, it is necessary to master the skill of installing or removing a transceiver modules to avoid unnecessary loss. This tutorial are going to guide you how to install or remove SFP transceiver module in a right way.

Things Should Be Know Before Installing or Removing SFP

Before removing or installing a Transceiver Module you must disconnect all cables, because of leaving these attached will damage the cables, connectors, and the optical interfaces. At the same time please be aware that do not often remove and install an SFP transceiver and it can shorten its useful life. For this reason transceivers should not be removed or inserted more often than is required. Furthermore, transceiver modules are sensitive to static, so always ensure that you use an ESD wrist strap or comparable grounding device during both installation and removal.

Required Tools

You will need these tools to install the SFP transceiver module:

1.Wrist strap or other personal grounding device to prevent ESD occurrences.

2.Antistatic mat or antistatic foam to set the transceiver on.

3.Fiber-optic end-face cleaning tools and inspection equipment

Installing SFP Transceiver Modules

SFP transceiver modules can have three types of latching devices to secure an SFP transceiver in a port socket:

1.SFP transceiver with a Mylar tab latch.

2.SFP transceiver with an actuator button latch.

3.SFP transceiver that has a bale-clasp latch.

Types of SFP Latching

Determine which type of latch your SFP transceiver uses before following the installation and removal procedures.

To install an SFP transceiver, follow these steps:

Step 1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis.

Step 2. Remove the SFP Transceiver Module from its protective packaging.

Note: Do not remove the optical bore dust plugs until directed to do so later in the procedure.

Step 3. Check the label on the SFP transceiver body to verify that you have the correct model for your network.

Step 4. Find the send (TX) and receive (RX) markings that identify the top side of the SFP transceiver.

Note: On some SFP transceivers, the TX and RX marking might be replaced by arrowheads that point from the SFP transceiver connector (transmit direction or TX) and toward the connector (receive direction or RX).

Step 5. Position the SFP transceiver in front of the socket opening.

Note: Different Cisco devices have different SFP module socket configurations. Your Cisco device could have either a latch-up or a latch-down orientation. Ensure that you are installing the SFP transceiver in the correct orientation for your Cisco device. Refer to the hardware installation instructions that came with your Cisco device for more details.

Step 6. Insert the SFP transceiver into the socket until you feel the SFP Transceiver Module connector snap into place in the socket connector.

Note: For optical SFP transceivers, before you remove the dust plugs and make any optical connections, observe these guidelines:
a. Always keep the protective dust plugs on the unplugged fiber-optic cable connectors and the transceiver optical bores until you are ready to make a connection.
b. Always inspect and clean the LC connector end-faces just before you make any connections. See the Required Tools section of this document for more information.
c. Always grasp the LC connector housing to plug or unplug a fiber-optic cable.

Step 7. Remove the dust plugs from the network interface cable LC connectors. Save the dust plugs for future use.

Step 8. Inspect and clean the LC connector’s fiber-optic end-faces.

Step 9. Remove the dust plugs from the SFP transceiver optical bores.

Step 10. Immediately attach the network interface cable LC connector to the SFP transceiver.

Step 11. Connect the 1000BASE-T SFP transceivers to a copper network.

Caution: In order to comply with GR-1089 intrabuilding lightning immunity requirements, you must use grounded, shielded, twisted-pair Category 5 cabling.

Complete these steps in order to connect the transceivers to a copper network:
a.Insert the Category 5 network cable RJ-45 connector into the SFP transceiver RJ-45 connector.

Note: When you connect to a 1000BASE-T-compatible server, workstation, or router, use four twisted-pair, straight-through Category 5 cabling for the SFP transceiver port. When you connect to a 1000BASE-T-compatible switch or repeater, use four twisted-pair, crossover Category 5 cabling.

b.Insert the other end of the network cable into an RJ-45 connector on a 1000BASE-T-compatible target device.
c. Reconfigure and reboot the target device if necessary.

Step 12. Observe the port status LED:
a. The LED turns green when the SFP transceiver and the target device have an established link.
b. The LED turns amber while STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the LED turns green.
c. If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be a problem with the adapter installed in the target device. Refer to the Troubleshooting section of your switch hardware guide for solutions to cabling problems.

Removing SFP Transceiver Modules

Step 1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis.

Step 2. Disconnect the network fiber-optic cable or network copper cable from the SFP Transceiver Module connector. For optical SFP transceivers, immediately reinstall the dust plugs in the SFP transceiver optical bores and the fiber-optic cable LC connectors.

Tips: For reattachment of fiber-optic cables, note which connector plug is send (TX) and which is receive (RX).

Step 3. Release and remove the SFP Transceiver Module from the socket connector.
a. If the SFP transceiver has a Mylar tab latch, pull the tab gently in a slightly downward direction until the transceiver disengages from the socket connector, and then pull the SFP transceiver straight out. Do not twist or pull the Mylar tab because you could detach it from the SFP transceiver.

b. If the SFP transceiver has an Actuator button latch, gently press the actuator button on the front of the SFP transceiver until it clicks and the latch mechanism releases the SFP transceiver from the socket connector. Grasp the actuator button between your thumb and index finger, and carefully pull the SFP transceiver straight from the module slot.

c. If the SFP transceiver has a Bale-clasp latch, pull the bale out and down to eject the SFP transceiver from the socket connector. If the bale-clasp latch is obstructed and you cannot use your index finger to open it, use a small flat-blade screwdriver or another long narrow instrument to open the bale-clasp latch. Grasp the SFP transceiver between your thumb and index finger, and carefully remove it from the socket.

Infiberone Starts Batch Production of 40G QSFP GEN2 Optical SFP Transceivers

40g-qsfp-infiberone

Infiberone announced last Friday it’s gone into the batch production of their newly released 40G QSFP GEN2 optical transceiver. The main difference between 40G QSFP GEN2 and existing 40G QSFP on the market lies in the multichannel real-time DDM function, which is easy to realize for transceivers with data rate lower than 10Gbps, but very complicated for those more than 10Gbps, as the latter is mostly based on COB not TO packaging technique. As for parallel high-speed optical transceiver with higher rate, it requires excellent design and precise layout to realize optic circuit detection on 4-channel or 12-channel array light chip in an extremely limited space, which has been met by Infiberone patented optical engine technology. Starting optical engine technology development since 2011, now by its own endeavor and cooperation with quality suppliers, Infiberone has gained rich experience and unique technology about array LENS development and integrated optical devices coupling capsulation. It is a critical mission for Infiberone R&D long-term works that realizing multichannel optical power DDM real-time monitoring of high-speed parallel optical module. Lack of optical power real-time monitoring does not influence optical modules regular operation; however Infiberone‘s been striving to create product higher than industry standard and holds firm pursuit of optical module complete functions, and finally they reach this goal.

It says that Infiberone new launched GEN2 optical module will not largely increase clients’ purchasing cost. The bulk price of GEN1 and GEN2 almost reach equilibrium, even GEN2 module is a truly flawless product compliant with related standards. Infiberone launched this new product at CIOE in September 2015, and now plans to completely switch the generation products in the first half of 2016.

By the way, Infiberone is going to attend OFC exhibition in USA this month, let’s meet there to communicate about new products.
