1.25G Multimode SFP LC Module, 1000Base-SX Fiber Transceiver for Cisco GLC-SX-MMD, Meraki, Ubiquit, Mikrotik, Intel, Fortinet, Netgear, D-Link and More (MMF 850nm,550m,DDM) 2 Pack

I recently bought a Cisco Nexus 3064-based router. With 48 10Gbps SFP ports, the X is an excellent choice. I needed a way to connect a FreeNas server to my new switch using two 10Gbps RJ45 nics. I took a chance and bought four of these, as well as some high-quality CAT8 cables, to ensure a reliable 10Gbps connection to the new switch. So far, everything has gone smoothly. I now have two 10Gbps connections to my FreeNAS server, with the other two being used to connect my pfSense Router to the Nexus via LACP. Despite the fact that the pfSense router lacks 10Gbps nics, it had no trouble negotiating a 1Gbps link to each LAG port. It will take more time to see if these are truly rock solid, but so far, so good. TLDR: TLDR: TLDR: TLDR: TLDR: TLDR: TLDR: TLDR In my Cisco Nexus 3064-based network, I have four of these. So far, I have had no issues.

Surprisingly, the 850nm multi-wavelength signal has been reported. fiber in mode Using in a MikroTik CRS305-based system A four-port 10GbE switch with four ports in each direction. Keep in mind that 1GBASE-T is a one-gigabit per second Ethernet connection. T modules use more power than fiber or DAC modules, so it's a little warmer. any 1GBASE-T Ethernet connection T module is going to do it. Check to see if your device is up to the task! br>br>The first unit I received caused me some problems. It would work for a few days before losing the connection. I had to uninstall and reinstall it to get it to work again. After re-inserting the module, it worked for a few more days. HiFiber, on the other hand, contacted me directly after I reported the problem and sent me a new one. Since that time, the replacement has performed admirably. This module does not support DDM, so no temperature or line conditions are reported to the switch. br>br>Great, five-star customer service!br>br>Unfortunately, this module does not support DDM, so no temperature or line conditions are reported to the switch. This, according to the manufacturer, is to be expected. It also reports as an 850nm multi-mode laser, which is strange.

This works for me most of the time, but there is one nagging bug, at least when using the CBS350 series: This transceiver informs the hardware that it is a 10-channel transceiver. Gigabit fiber with a 10-year warranty This correctly negotiates the link speed at the transceiver level and passes packets at 1 gigabit and 2 gigabit speeds, regardless of the actual link speed of the attached device. br>br> Speeds of up to 5 gigabits per second are possible. However, I'm concerned that the switch thinks the link can handle 10 gigabits of data. br>br>I have no idea what problems this will cause in practice, but I'd anticipate a high rate of packet loss as the link speed approaches, because the switch won't realize it needs to buffer packets. Of course, you can slow the link down to a crawl. The CBS350 series, however, does not allow you to force a two-gigabit connection. 5 gigabits speed of a gigabit br>br>I'm not sure if the problems are due to Cisco bugs, transceiver firmware bugs, or a combination of the two. In any case, until this reporting issue is resolved, I'd steer clear of this transceiver on Cisco 350-series switches. If you want to use a link speed other than 10 Mbps, you'll need to buy a series of hardware. Gigabit or a single gigabit.

It was easy to use with my Cisco WLC 5760. br>Fast shipping.

Is this useful in more ways than one?.

Compatible with the Cisco GLC-T T/SFP- T, M. " A H product! Fiber. The RJ45 male connectors on these modules don't always click into the female receptacle on the module, which causes some connectivity issues. There is no audible click, and the cables frequently do not seat and will pull out if not wiggled into place. I had the same problem with two other brands in the same price range (Ipolex and 10Gtek), and yes, I tried different Ethernet cables - br>They do not work on the Mikrotik CRS305 product line, and RouterOS lists these modules (and another brand in the same price range) as OEM SFP-compatible. Devices with the letter T I put them to the test on RouterOS v7. On v6 and 1rc3 (testing). 4 (steady). The only ones with which I've had no problems are QSFPTEK 10GBASE-T and QSFPTEK 10GBASE-TX. T SFP modules, which is unfortunate because I don't require 10Gb RJ45 for my application and they cost around $44 per module at the time of writing. This review will also be cross-posted on the other devices I bought and tested.
