Direct Connection for Cisco 40G QSFP+ LR4 Transceivers
How to connect two Cisco 40G QSFP+ LR4 transceivers directly? A LC UPC to LC UPC duplex single mode fiber optic patch cable is required. The Figure below shows two 40G QSFP+ LR4 transceivers connected by a single mode LC cable.
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.

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.

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.

No, the FS.COM 40GBASE-LR4 QSFP+ transceivers use 4 wavelengths on a pair of single mode fibers, and do not lend itself to “splitting” into 4 pairs without substantial complexity to split out the wavelengths.

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.

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.

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.
We are building a new data center as well as we do inside plant/structured cabling. Their price is right so we just had to try your stuff out. Assuming the quality is comparable to the big boys, we will be order more.
