Hello, yes, the three products you purchased can compatible together. You can connect them according to the following steps: QSFP-4X10G-LR-S---->MTP trunk cable #43985---->96 fibers Patch Panel Flat #43552---->singlemode duplex LC/LC fiber patch cable---->10G-LR SMF SFP+.

The FS.COM 40GBASE-PLR4 QSFP+ transceivers use 12 fibers single mode MTP Type B trunk cables for direct connection such as #68018 and as for 10G to 40G network speed upgrade connection, 8 fibers single mode MTP-LC Type B harness cable #68048 can be applied. от FS.COM 10/04/2017

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. от FS.COM 07/15/2017

Yes, the FS.COM 40GBASE-PLR4 QSFP+ transceivers are fully compatible with 10GBASE-LR and 10G-LRL up to the maximum distance of each optic, and use single mode 8 fibers MTP Type B harness cable #68048. от FS.COM 06/11/2017

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. от FS.COM 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. от FS.COM 06/05/2017

FS.COM has been maintaining huge stock level of the 40GBASE-PLR4 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. от FS.COM 05/06/2017

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. от FS.COM 04/12/2017

The FS.COM 40GBASE-PLR4 QSFP+ transceivers support up to 10km over single mode fibers. от FS.COM 04/03/2017

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 40GBASE-PLR4 QSFP+ transceivers. от FS.COM 03/21/2017
