Today's Data Center Interconnect (DCI) networks are reaching a critical juncture. High capacity data transport between data centers is a vital need in enterprises to support the growing demands for data transmitted at any time and from any place. To meet these challenges, cloud providers, enterprises, and service providers' data center must use high-end DWDM optical network solutions for transporting multiple 10G/40G/100G services.
Ring configurations can be deployed with one or more DWDM systems, supporting any-to-any traffic, or they can have a hub station and one or more OADM nodes, or satellites. It is a resilient optical transport service that delivers more robust transport networks and Increases operational efficiency.
Allowing intermediate locations to easily access the common fiber. Using the east and west CWDM OADM modules, network designers can add a new one or more access points anywhere on a CWDM network, without impacting the remaining channels traversing the network.
CWDM wavelengths range from 1260-1625nm, channel spacing is 20nm, which actually cover all the range of DWDM wavelengths (1470-1625nm). And DWDM wavelengths have much smaller channel spaces (0.4nm/0.8nm). Therefore, the CWDM wavelengths near DWDM wavelengths can be used to transmit the DWDM wavelengths.
Newly Released 40/100G Optical Transport Solutions
Today's enterprises and service providers are eager to lower bandwidth costs and provide more scalability. But this is far from easy with traditional OTN technology. You need a solution to optimize bandwidth and network management, as well as enhance the flexibility of network. You need FS.COM Multiservice Transport Platform.

Sorry, 100G QSFP28 transeivers that operate at an industrial temperature range are currently not available, but in development. Please stay tuned. By FS on 17/02/2018
The FS.COM 100GBASE-SR4 QSFP28 transceivers use 12 fibers OM4 MTP Type B trunk cables for direct connection such as product #68017 and as for 25G to 100G network speed upgrade connection, 8 fibers OM4 MTP-LC Type B harness cable #68047 can be applied. By FS on 21/10/2017
As for customized transceivers, FS.COM offers regular custom choices such as compatibility, transmission distance, operating temperature, label pattern, label colors and etc. What's more, FS.COM welcomes any inquiry for customized products and solutions for all need and specifications. By FS on 08/08/2017
Besides the price advantage we have compared to branded transceivers, FS.COM compatible transceivers also maintain the same performance and reliability. To satisfy our customers' needs of high performance, all of our transceivers are tested multiple times in mainstream original brand switches in our test center before shipped out. By FS on 08/07/2017
No. The 100G QSFP28 form factor has just 4 electrical lanes, which is not enough to support 10 lanes of 10G electrical interface. A 100G QSFP can only support a 4x10G or 4x25G electrical interface, which can be used as 4x10GbE or 4x25GbE, but not 10x 10GbE.As a result the 100G QSFP SR4 cannot interoperate with SR10 based 100GbE transceivers. By FS on 21/06/2017
Dust and contamination can accumulate on transceiver's connectors and cause problems such as reducing the optic launch power. To ensure better connection, FS.COM strongly recommends cleaning both connectors each time you disconnect and reconnect them. FS.COM High Quality One-Push Fiber Optic Pen Cleaner for MTP/MPO Connector is the best cleaning choice for 100GBASE-SR4 QSFP28 transceivers. By FS on 10/06/2017
No. Network equipment manufacturers do not require that you use only name-brand optics. In fact, when a product fault or defect occurs in the network, and the fault or defect is not attributable to the use of third-party optics, they will continue to provide support for the affected product under warranty or covered by their support program. By FS on 06/06/2017
We supply a huge volume of optics to a variety of customers, so in most cases we have all of the most popular optics in stock, ready to ship. However, some of the higher-value and specialized optics have a short lead time. You can find the stock information and the estimate delivery date from the product page easily, or contact sales@fs.com directly before you place the order. By FS on 05/06/2017
The maximum power consumption of 100GBASE-SR4 QSFP28 transceivers is 3.5W. If it draws greater than 3.5W, FS.COM can not guarantee the performance since there are other dependencies like airflow direction, ambient temperature, elevation and etc. By FS on 03/06/2017
Due to an urgent project, we needed 30pcs QSFP28 SR4 soon. Then I placed an order and the website showed it would be shipped from Seattle directly. I ordered F5 compatible parts, but I received Cisco parts. They explained the Cisco parts could replace the F5 parts. But based on the feedback from our engineers, we've met big problems when we connected Cisco parts with Juniper parts together before. It's an important project and we couldn't take the risk. So we required a replacement and they did a fast shipment. I love their service!
I really worried about third-party modules previously, especially for 100G modules. My sales Shirley shew me their 100G switch for testing and promised to send me test report before shipment. Then I tried. The test result is beyond my imagination and it works well on my Cisco switch. It's important to keep trying. You will find much good things.
I'm a businessman from the United Kingdom. I began to place optical orders from Fiberstore several months ago, but sincerely I have to say that I love shopping at here. Last week, I added another 8pcs QSFP28-SR4-100G for my customer, and received them within 3 days with free shipping, also trust they will work well as previous. Hope more and more inventory would reach its European Warehouse.
My friend recommended FS.COM to me before, so I placed a testing order. Everything goes well. Since then, I often make purchases from FS.COM and I have always had excellent customer service. I would like to buy QSFP28-SR4-100G from FS.COM because it has better quality with low price.
We were in the planning phase of a major 100G campus-wide upgrade. There is no doubt that I will use Fiberstore optics for those upgrades. I had bought many 40G optics from them. They worked well as always. And the price of 100G SR4 cut down, so I seized the chance to order all we need.
As always, the packaging and shipping was very well done and everything is accounted for. Thank you. Your shipping team has done a good job on this order and I do appreciate the detail that is placed on shipping such a large and varying product base in a single shipment.
We had a large volume for 100G transceivers each month. FS 100G transceivers
always had good performance. This time our Account Manager told me that it had a big price reduction, so we purchased some more which can be used for six months. Surprisingly, we received the goods quickly. That's great.
I haven't even had this 24 hours and I can honestly say it's one of the best and most beneficial products I have bought for our Extreme switches!! brilliant product, delivered earlier than originally stated and work excellent
