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.

Sir, thanks for your question. The qfx-QSFP+40G-LR is LC ports, so cannot connect QFX-10G-LR directly. You can choose #36440 #68047 #31287 to form a complete 40-4*10 connection. The length can be customized. By FS on 12/07/2018
Sorry, 40G QSFP+ transeivers that operate at an industrial temperature range are currently not available, but in development. Please stay tuned. By FS on 03/17/2018
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 07/15/2017
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 06/07/2017
On one hand, the FS.COM 40G QSFP+ transceivers with LC interface are used for long-distance transmission over single mode fiber, and those with MTP/MPO interface are utilized for short distance transmission over multimode fiber. On the other hand, for the FS.COM 40G QSFP+ transceivers with LC interface, they cannot be split into 4x10G as they use 4 wavelengths on a pair of single-mode fibers and do not lend themselves to “splitting” into 4 pairs without substantial complexity to split out the wavelengths. For the FS,COM 40G QSFP+ transceivers with MTP/MPO interface, they can be used in 4x10G connectivity via an external 12-fiber parallel to 2-fiber duplex breakout cable, which connects the 40G transceiver to four 10G optical interfaces. By FS on 06/05/2017
No, the 40G QSFP+ LR4 Transceivers cannot work with 10G LR transceivers directly because the 40G QSFP+ LR4 Transceivers uses LC connectors instead of MTP/MPO connectors. If you need transceivers to have 4x10G connectivity, the #QSFP-PLR4-40G Transceivers are highly recommended. By FS on 05/25/2017
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 1.25mm LC/MU Connector is the best cleaning choice for 40GBASE-LR4 QSFP+ transceivers. By FS on 05/21/2017
FS.COM has been maintaining huge stock level of the 40GBASE-LR4 QSFP+ transceivers in U.S. warehouse, EU warehouse and CN warehouse. As long as the products you order are all in stock, we will ship them out the same day you place your order. As for some specific products or products that have a short stock, we will keep you informed ahead of time before you place your order. By FS on 05/14/2017
This module works perfect. I have 3 pairs of these and all of them work stable. My dark-fibers are longer than 10km but the link is stable even with attenuators. The lower optical power budget is approx. -17dBm. Im using one of the pairs over a 18km route, both modules are receiving -15dBm and they are working stable, without port flapping or interface errors. I will confidently purchase these modules again in case of need.
As a suggestion, I can recommend that Fiberstore produce a version of these to work over 4 wavelengts 1490-1550nm instead of 1270-1330nm. Thats very much required for operation over G.655 fibers.
Considering the original transciver is expensieve and we have so many datacenter projects to bulid as we are a professional data outsourcing company. So we want to try some third party transceiver to save more budget. And I found FS.COM from Reddit, which there is a topic that had some pepole talked about their optical products and the recommention is high. I decided to buy 2pcs Cisco compatible ones and mathed MTP truck cables to have a try on our Alcatel-Lucent Omniswitch 6900 switches, evrything expressed good, Besides, the product has a strong sense of quality. That's really satisfied. We will try more....
Our switch is HP5900A, I bought an HP-compatible module (corresponding ID) directly on FS.COM, because I didn't clear the compatibility problem too well, I couldn't use it after I receive it. Then I asked FS technical support and they gave a very fast reply. Finally, to indicate that because I confused the compatibility and indeed could buy H3C-compatible directly and the price was cheaper than HP; my sales quickly helped me handle the return issue. After receiving the H3C-compatible module, I Plug in use, everything is normal. Well done~
Works well with Cisco 2900 switches. I can't remember how many I've purchased from FS. What I can confirm is that you'll not feel regret for choosing FS.
FS.COM had been recommended to us based on the quality of the transceivers, their affordability, and their unbeatable lifetime warranty. We renewed almost all of our old transceivers on a tight budget, and they have all been giving us entire satisfaction so far. The purchasing process which was very pleasant, from our first initial contact with a representative (within 24-hour response time from our original information request) to delivery. I would recommend FS in a heartbeat! Thanks again!
I do see some potential on FS's product. I purchased 8pcs modules from FS.COM to go into a Cisco Switch. The items work fine. I would definitely buy this again.
This item shipped fast and arrived same day as promised. Good Low Cost but work good with my Cisco 2960 switch. Was perfect for my needs. No configuration needed, it was truly plug and play. Looking to purchase again soon.
