FiberStore designs, manufactures, and sells a
broad
portfolio
of
optical
communication
products, including passive optical network and
optical transceivers. The optical transceivers
include SFP, SFP+, XFP and so on. And the SFP
transceiver is the cheapest and most commonly
used version among them.
Then, which types of SFP transceivers does FiberStore supply?

According to the brands, FiberStore's SFP transceivers are divided into two big parts:
compatible SFPs and custom SFPs. The compatible SFPs include most famous brands such
as Cisco, HP, Juniper, Dell, Netgear, Extreme, Force10, 3Com, etc.. The custom SFPs can be
any type up to the customers’ requirements and own the brand of FiberStore.

According the different parameters and applications, FiberStore's SFP transceivers include
100M & 1G SFP, SONET/SDH SFP, 4G SFP, CWDM & DWDM SFP, BIDI SFP, and
Copper & SGMII SFP.

100M & 1G SFP
The "100M & 1G SFP" is just a short name of Fast Ethernet & Gigabit Ethernet SFP and
sometimes called FE & GE SFP. Fast Ethernet SFP (100BASE-X) is a hot-swappable input/output
device that plugs into a Fast Ethernet port or slot, linking the port with the network, while Gigabit
Ethernet SFP transceivers are designed to use with Gigabit networks. They are all compliant to
IEEE 802.3 standards and have different types to fit for 1000Base-SX, LX/LH, EX, ZX and
1000Base-T applications. FiberStore provides a complete range of FE & GE SFP modules with
the features below.


SONET/SDH SFP
FiberStore's multi-rate 2.67Gbps transceivers integrate optics and electronics in a SFP. These SFP
modules are compatible with the SONET/SDH and ATM standards, and provide a fully OC-48
SONET compliant interface between the SONET/SDH photonic layer and the electrical layer.
Although optimized for OC-48/STM-16, the SONET/SDH SFP modules provide multi-rate
capabilities and can be used from OC-3/STM-1 (155 Mbps) up to 2.67Gbps. For example, they
can support OC-3/STM-1, OC-12/STM-4 (622 Mbps), and OC-48/STM-16 (2.488 Gbps) data
rates for multimode, short-reach, intermediate-reach, and long-reach applications. Most
SONET/SDH SFPs have features as below.

3. 
4G SFP
4G SFP is most used in Fibre Channel application. It is a a high performance, cost effective
module at data rates of 4.25Gbps. It supports 4x/2x/1x Fibre Channel and is also compatible with
Gigabit Ethernet as specified in IEEE Std 802.3. It is fully compliant to the SFP Multi Source
Agreement (MSA) and the Fibre Channel 400-M5/M6-SN-1 specification. The transmitter uses a
VCSEL, FP or DFB laser, and receiver uses an APD or PIN photodiode integrated with a
trans-impedance preamplifier (TIA). All FiberStore's 4G SFP modules are class 1 laser safe and
can come with digital diagnostic monitoring (DDM). They are with different data rates, including
4G & 2G Fibre Channel SFP. And there is also 8G Fibre Channel SFP as a plus type. The feautres
are as showing below.


CWDM & DWDM SFP

CWDM SFP provides scalable and easy-to-deploy Gigabit Ethernet and Fibre Channel
services in optical networks. It enables the design of flexible multiservice networks. The
CWDM SFP consists of three sections: an uncooled CWDM DFB laser transmitter, a PIN
photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit.
There are 18 center wavelengths available from 1270 nm to 1610 nm, with each step 20 nm.
These wavelengths are compliant to the ITU G.694 CWDM standard.
