SFP CONVERTERS

MiRICi-155

Gigabit Ethernet over

STM-1/OC-3 SFP Converter

The innovative SFP-format MiRICi-155 is a

miniature converter, delivering Gigabit Ethernet

(GbE) services over existing SDH/SONET

networks, simply and cost effectively.

The MiRICi-155 maps GbE frames into VC-4 or

STSc-3, using standard GFP encapsulation

according to G.7041/Y.1303. This allows book-

end connections as well as third-party

interoperability.

Housed in a small form-factor pluggable (SFP)

enclosure, it is designed for quick and simple

insertion into any Ethernet device port with a

compatible SFP socket.

The MiRICi-155 is a simple and cost-effective

alternative to external, standalone converter

units or conversion cards for user devices.

Deriving power from the host device, it requires

no additional power supply and offers

significant savings in space, cabling and power

consumption, as well as simplifying

management.

The MiRICi-155 features a standard Multisource

Agreement (MSA) edge connector as the GbE

interface, supporting 1000BaseX in full duplex

mode. Connection to the STM-1/OC-3 link is

performed via a standard FO LC connector.

Inband and out-of-band management

The MiRICi-155 can be managed out-of-band

through the I

2

C serial bus on the MSA

connector. Inband management is performed via

any Web browser, as the Web agent is

implemented inside the MiRICi-155.

The MiRICi-155 supports flow control by

generating standard pause frames whenever the

internal buffer reaches its high water mark,

thereby adjusting the bandwidth between the

LAN and WAN as necessary. In addition, it

supports fault propagation from the WAN to the

LAN.

End-to-end quality of service (QoS) is enabled

using four priority queues per VLAN priority

(802.1p) and ToS.

In addition to supporting MSA product

identification codes, the MiRICi-155 is hot-

swappable and features a special release

mechanism for easy extraction from the SFP

socket.

The economical SFP plug format is an ideal and

affordable solution for carriers and service

providers bridging GbE LANs over SDH/SONET

WANs, as well as for similar applications in

private enterprise and campus networks.

Providing transparent LAN services over SDH/SONET networks

MiRICi-155 can operate opposite MiRICi units

installed on remote equipment or opposite RAD’s

RICi-155GE Gigabit Ethernet over STM-1/OC-3 NTU.

Alternatively, the MiRICi devices can operate

opposite any Ethernet switch that supports

standard GFP encapsulation.
