SFP Network Receiver & Transceiver Modules in Bangladesh 

Smarter Connectivity Starts with the Right Transceiver

At TechBox, we provide high-performance SFP (Small Form-Factor Pluggable) network transceiver modules designed for seamless integration with switches, routers, and OLT devices.

These modules act as the bridge between your networking hardware and fiber or copper cabling — delivering high-speed, stable, and long-distance connectivity for modern data networks.

Whether you need single-mode or multi-mode, Gigabit or 10G, TechBox ensures you get the right SFP module with genuine performance and brand warranty — because we don’t just sell parts, we deliver network solutions.

What is an SFP Network Receiver?

An SFP network receiver is the component within an SFP transceiver responsible for receiving incoming data signals.

It captures light (in optical modules) or electrical pulses (in copper modules) and converts them into digital data for your device — ensuring reliable, high-speed communication across your network.

How an SFP Receiver Works

In Fiber-Optic Networks

Light pulses travel through fiber cables carrying encoded data.

The receiver’s optical bore (Rx) captures these signals.

A photodiode converts light into an electrical current.

Amplifiers boost and clean the signal before delivering it to your switch or router.

 In Copper Networks

The receiver processes electrical pulses directly from Ethernet cables.

It outputs the network signal at the correct bitrate for data transmission.

Types of SFP Modules and Their Receiving Capabilities

SFP Module Type Cable Type	Cable Type	Wavelength (nm)	Maximum Distance
Multimode SFP (1000BASE-SX)	MMF	850	Up to 550m
Singlemode SFP (1000BASE-LX)	SMF	1310	Up to 10km
Long Range SFP (1000BASE-ZX)	SMF	1550	Up to 80km
Copper SFP (1000BASE-T) RJ45	RJ45	N/A	Up to 100m
BiDi SFP	SMF	Dual wavelength	Up to 80km

TechBox offers a variety of SFP modules for different distances and transmission speeds, ensuring compatibility with both enterprise and ISP-level infrastructures.

Key Receiver Specifications to Consider

Receiver Sensitivity: Minimum input power level for accurate signal detection.

Overload Power (Saturation): Maximum input power before distortion occurs.

Wavelength Compatibility: Match module wavelength with network fiber type.

Temperature Stability: Industrial SFPs perform better under heat and voltage stress.

At TechBox, we help you choose the right SFP module based on your existing network topology and performance needs.
