    Cisco SFP-10G-LR-S Compatible 10GBASE-LR SFP+ Transceiver Module (SMF, 1310nm, 10km, LC, DOM)

     

    The Cisco SFP-10G-LR compatible SFP+ optical transceiver with an LC duplex connector reaches a link up to 10km over OS2. This 10G SFP+ transceiver is verified to interoperate with original Cisco switches, ranging from enterprise access switches (such as Catalyst 2960/3850 series) to data center core switches (such as Nexus 9000/7000 series). QSFPTEK manufactured 10GBASE-LR SFP+ transceiver module is compliant with SFP+ MSA, IEEE 802.3ae, SFF-8472. Besides, DDM (digital diagnostics monitoring) function is supported on the 10G fiber optic transceiver to achieve real-time operating parameters monitoring.

      We've been using the 10G LR modules for building-to-building links, and they've been rock solid. Plugged them in, links came up immediately, no tuning or weird compatibility issues. Running close to the full 10 km range on single-mode fiber with stable performance. For the price, it's a reliable choice for enterprise networks.

      This 10GBASE-LR module has been a simple, no-nonsense solution for long links. Plug it in, connect the fiber, and it's up without any extra steps. It's been running quietly in the background with steady performance and no surprises.

      I installed this 10G LR transceiver in my Cisco switch, and it worked right away with no compatibility issues. The stable link over SMF is holding strong at around 8 km, and so far, there haven't been any packet drops. The build feels sturdy, and hot-swapping was smooth. Shipping took a bit longer than I expected, but the product itself is great.

      This is the first time I bought an optical module from QSFPTEK. The quality of the product is very good. It can be recognized and used directly after plugging it in. The heat control of the module is also good, so there is no need to worry about long-term use. The only shortcoming is that I hope the packaging can be strengthened to avoid damage during the express delivery process.

      We purchased a large number of 10G-LR modules at one time. When purchasing these modules, we obtained large order discounts from the sales. It made our finances easier. To be honest, although QSFPTEK's price is low, its product quality is not inferior to others.

      The shopping experience is good, the shopping process is simple, and the button functions are clear and easy to understand. For some 10G SRs placed in bulk, you only need to click bulk order and fill in the quantity, and then the account manager will contact you.
