The Solution to SFP Transceiver Module Connections

Recently I met a trouble that when I want interconnect WS c2960 24 TC L + 2SFP with 1000base LH GLC LH SMD or GLC LH SM to WS C3750G 12S + 12 SFP ports, and I do not know which model of GLC LH SMD or GLC LH SM want to select, and I am going to use single mode fiber optic cable 1310m 9/125. If I need single mode SMD (2 fiber counts) or single fiber. I just want to find out WS C3750G12S + 12 SFP ports that 12 SFP ports are SM or SMD use LC connector.

In fact, I received several answers, someone says, the price between the 2 usually the same but GLC LH SMD supports additional option of DOM (digital optical monitoring). So he uses GLC LH SMD, as for which fiber cable, just use the single fiber cable, but I think so I use SMD how can I use single fiber cable, this is one way direction and i think i should use single mode duplex (2 fiber count). And can connect single mode duplex (2 fiber count) fiber cable to WS C3750G 12S.

fiber optic transceiver

Then someone from Fiberstore answered me that both the GLC LH SM and GLC LH SMD transceivers support the IEEE 802.3 1000Base LX/LH standard and be good for compatible with each other. The difference between the two is the case that the GLC-LH-SMD transceiver has additional support for Digital Optical Monitoring capability. As for the second question, 1000base fx sfp, 1000base sx sfp, 1000base lx lh sfp, 1000base zx sfp, 1000base bx10 sfp, DWDM and CWDM SFP Transceivers: LC fiber connectors (single-mode or multimode fiber); 10GBASE-SR, LR, LRM, CX1 (v02 or higher) SFP+ Transceivers: LC fiber connectors (single-mode or multimode fiber).

Then if you have such similar problems, hope it can help you, and there I have a small tips for us, if you want to know where to get sfp transceiver and reach these effects, Fiberstore is a good place to get them, I found it do a professional site, and the price also reasonable, It is worth mentioning that Fiberstore is doing a big sales.

What Technology Should be Valued at the Next Generation Data Center Network

With the continual?expansion of business data center, the most several difficult problems for them are mainly about divided network environments, simple says, separate data network, separate storage network, separate calculation?network, protocols and there are different disadvantages of standards. Different networks need different cards, space, power and cooling infrastructures for their business. Interspersed interlaced network cabling may make many administrators feel dizzy. Aimed at different network environments, the company needs a professional technical team to support, manage, maintenance, these problems all block the forward developments of data center, let alone meet the future of cloud computing.?The figure shows?modern data center.

Modern data center

You may ask, what qualities we are taken for the next generation data center networks? Now we can see the characteristics, such as simplicity, virtualization features, can accommodate the expansion of the size of the data center, support higher bandwidth, low latency, non-blocking and so on. But as for these features, mainstream network equipment vendors aimed the advantages of their products and solutions to this goal, so if there is an architecture able to support these features do? The answer is yes, unified architecture (Unified Fabric), regardless of Cisco UCS. Brocade VCS, juniper3-2-1 plan, H3C’s unified fabric, also exist Unified Fabric. This page we just say two points.

The key technology under Unified Architecture (Unified Fabric)

Gigabit Ethernet

With the reduction of gigabyte networks at the server connections, Gigabit Ethernet share is rising, which maily due to the growth in the enterprise data center network traffic.In fact, with the 40G / 100G standard developments, it is sure that Gigabit Ethernet replacing the gigabyte networks, the birth of the Gigabit sfp+ transceiver?standard which has low power, sfp+ direct attach cable?can be achieved in the case of low-cost Gigabit Ethernet. And just mainstream might not be enough, the following what I will be introduced to toward greater success.

FCoE protocol (Fiber Channel over Ethernet)

FCoE is one of the most shining technology data center network currently, any vendors have to talk about the technology of the developments of their products. FCoE refers to the Fiber Channel over Ethernet, it can insert fiber channel information into the Ethernet packet, so that the Fiber Channel storage devices -SAN server requests and data can be transmitted over an Ethernet connection, without the need for a dedicated Fiber Channel fabric . Its main benefits: First, make storage traffic and network traffic share the same Ethernet cable and a fusion of the card, simplifying management and reducing energy consumption. Second, provide the same performance with optics. The third is the ability to integrate effectively existing SAN.

Finally, you know, now i work for Fiberstore and in our website, we can provide the most advanced technology and the most effective way to help you solve the fiber optics problems, and at the same time, we also provide all the fiber optic products, such as 10 100 1000base t ethernet sfp, qsfp 4x10g aoc7m and glc fe 100lx rgd to buy. If you are interested, take a decision for it.

Choose and Get SFP+ Module and Cables Effectively

According the standard of the IEEE 802.3 ae committee ratified the 10 Gigabit Ethernet and with the general specification, it defines a number of fiber optic interfaces. These standard interfaces attempted to satisfy a number of different objectives including support for MMF and SMF compatibility. They include SFP+ sr transceiver, sfp+ lr transceiver, SFP+ er transceiver, SFP+ zr transceiver, Copper CU SFP+, maybe some one do not know the last one, related product you can see: cisco sfp h10gb cu2m. Their applications are using 10 Gigabit Ethernet and 2x/4x/8x/16x Fiber channel, for example, the cisco SFP+ module, the optical interoperability with 10Gbase XENPAK, 10 GBase X2, and 10GBase XFP interfaces on the same link; the device can olug into an Ethernet SFP+ port of a Cisco switch, just do not need to power down if installing or replacing, these are all its adavantages. the Cisco quality ID feature enables a Cisco platform to identify whether the module is certified and tested by Cisco. Then many people also think this problem that when we use the cisco transceiver with cisco switches or even patch cables, do they need the vendor ti phydiacally hang the access points and do they need eo configure the access points and how many buildings will the access points be installed into, well, the next paragraph will give you the answer.The vendor needs to phydically hang the access points and the points are controller based and they will need to be configured. All access points are to be installed on the ceilinf, the only exception would be in gym where it would to be mounted to the ceiling beam. The Figure show that push the SFP Front of the module to make it into the slot.

plug into sfp transceiver

Many people know that SFP, SFP+ and they are not familiar with QSFP, then i will introduce one kind of QSFP transceiver to you. The 40 Gb/s QSFP+ transceiver. It is a kind of fiber optical modules with four independant optical transmit and receiver channels, it combines the higher density attractions of modules with some the key advantages normally associated with SFP+ based modules. And another product you also can not forget, sfp+ direct attach cable. In Fiberstore, there is a similar attach cable, sfp+ direct attached twinax copper,it is suitable for very short distances and offer a usful way to connect within racks and across adjacent racks. Cisco offers passive twinax cables in lengths of 1, 1.5, 2, 2.5, 3 and 5 meters, and active twinax cables in lengths of 7 and 10 meters. related product: 0.5 m sfp+ cable.

sfp+ cable

And Fiberstore’s product are fully compliant with different brands, such as Cisco, hp, huawei, Finisar… and standards like Ethernet, Fibre Channel, Infianiband, SONET/SDH/OTN and PON standards, 1g sfp and 10g SFP+ and other transceivers that not mentioned such as WDM module, Bidi module all can get from Fiberstore. We have real wide variety of fiber optic transceivers, I do believe that it is a quite great choice for you.
