Frequently Asked Questions
Do I need to buy two SFP modules for one link?
Yes. The bi-directional modules stocked here work as a matched set, with one unit at each end of the fiber run. Ordering a single module leaves you without a working link.
Will a TP-Link SFP module fit my switch?
It depends on the switch. Check that your switch or router has an SFP port and that the manufacturer lists the module as compatible. Our team in Karachi can check this against your model before you order.
Can I get SFP modules delivered outside Karachi?
Yes. We ship nationwide across Pakistan and accept cash on delivery or online payment. The showroom in Karachi is available if you would rather collect in person or discuss the setup first.
TP-Link SFP transceiver modules for fiber links between switches, racks and buildings. Sold in matched pairs, with nationwide delivery across Pakistan.
SFP Modules and Transceivers
SFP transceiver modules plug into the SFP cage on a managed switch or router and give that port a fiber connection instead of a copper one. Network engineers buy them when a run has to cross more distance than a copper cable handles, or when two switches in separate racks, floors or buildings need a link that stays clean over that span. The module itself is the part that converts the signal, so it is bought alongside the switch rather than instead of it.
The selection in this category is narrow and built around TP-Link. What sits here are bi-directional modules, which pair up so a single fiber run carries traffic in both directions rather than needing one strand each way. Because of that pairing, the two ends of a link take complementary modules and are ordered together. Prices run from entry level through to premium depending on the module you pick.
Three things decide whether a module works for you. First, the switch or router has to accept it, so check the SFP port on the hardware you already own before ordering. Second, bi-directional modules only function as a matched set, so order both ends of the link at the same time and keep track of which unit goes on which side. Third, match the module to the fiber that is already pulled through the building, because the cable type and the connector on it govern what you can fit.
Who buys these
An office running a fiber backbone between floors uses a pair of these to bridge two switches without laying fresh copper. A small business linking a warehouse to a front office over an existing fiber run needs the same pairing. If you are after the switch, the router or the fiber patch cable rather than the optic that goes in it, our Network Switches, Fiber Optic and ONT Devices and Network Cables categories carry those.
Mega Computer stocks networking hardware at its Karachi showroom and ships nationwide across Pakistan. You can pay cash on delivery or through online payment. Modules carry the manufacturer warranty that applies to the product, and our staff can confirm which pair suits the switch you are already running before you place the order.
