SFP Module

What Is SFP Module?
SFP means small form-factor pluggable. It's a compact and hot-pluggable
transceiver which is commonly used in telecommunication and data communication.
SFP is often called mini-GBIC (Gigabit Interface Converter). It is with a
smaller size and it has already taken the place of GBIC modules in most 1Gb
applications. Currently, most SFP is fiber optic SFP types and most of them are
used for gigabit and 10G devices. 100M SFP modules are still in some needs, but
it's decreasing. Optical SFP modules are designed with a wide range of
transmitters and receivers for multiple distance needs. They are also applied
with various wavelengths to meet different optical signal transmission. There
are also SFP modules designed for Ethernet ports, they can convert fiber ports
into RJ45 ports.

SFP offers a convenient way for different wavelength and distance needs in the
network. Most of our gigabit switches are also designed with SFP versions in
order to meet the requirements. Unlike fixed fiber modules on normal switches,
SFP modules can be replaced easily according to different application
requirements.

What Kinds of SFP Module Does HS Offer?
The most common SFP modules transmission rate is 1.25G and 10G. SFP modules are
also divided into single-mode fiber and multi-mode fiber. Single-mode fiber can
reach the longest distance as 120KM. Multi-mode types meet the demand for
short-distance transmission needs, which can be up to 600 meters. Mainstream
SFP modules in the market are still single fiber types.

SFP modules can be categorized into different versions under Gigabit Ethernet
standards and industry-accepted standards, including 1000BASE-T, 1000BASE-TX,
1000BASE-SX, 1000BAS-LX, 1000BASE-LX10, 1000BASE-BX10, 1000BASE-LX/LH,
1000BASE-EX, and 1000BASE-ZX. HS has developed a full range of commonly needed
1.25G and 10G SFP modules types.

What Else Should We Know About SFP Module?
Except for single-mode and multi-mode, SFP modules are also divided into single
fiber and dual fiber types. We also call them simplex and duplex types. For
simplex types, we only use a single fiber cable for data transmission. As for
Duplex type, 2 fiber cables are required as there are individual transmitting
and receiving ends. Simplex SFP modules are also called bidirectional (BiDi)
SFP modules. The most commonly used wavelength for simplex types is
1310/1550nm, 1310/1490nm. All SFP modules should be used by pairs. For duplex
SFP modules, we have to use SFP modules with the same wavelength on the two
sides otherwise they will not be able to communicate. However, it's opposite
for simplex SFP modules. On the 2 sides we need to use opposite wavelengths,
which we will mark with A and B for you to tell. A should always be connected
with B on the other side.

The Sealed SFP optical and electrical integrated modules are designed to
maximize valuable space on the PCB. It creates great convenience for customers.
We offer wide range of SFP module types as well as SFP fiber optic switch to
enrich your network infrastructure.
