MRV Products
For more than
a decade, MRV Communications has brought to market innovative optical data
communication solutions that enable more and greater services to be carried over
the world's growing fiber infrastructure. Today, its family of WDM solutions
represents the latest evolution of fiber optimization. With hundreds of network
installations worldwide, MRV is a proven leader in WDM technology.
Positioned as a midrange WDM solution, the Fiber Driver™ Modular CWDM
system brings an unprecedented level of flexibility and scalability to metro and
intracity district networks, and campus and enterprise networks. By separating
the active data channel cards from the passive Mux/Demux unit, the modular
system enables customers to mix and match the protocols they want, and to deploy
their WDM solution one data channel at a time.
At the heart of the
Modular CWDM system is the Fiber Driver CWDM Passive Mux/Demux module. Protocol
independent and requiring no power, its operation remains transparent to both
the network and the end user.
The supported wavelengths of the CWDM
Passive Mux/Demux modules fall within the ITU-T G.694.2 (2002) standard of 1470
nm to 1610 nm with 20 nm spacing. An optional 1310 nm service channel is
available. The device is available in 4-channel and 8-channel configurations,
dual and single fiber.
The Fiber Driver Modular CWDM system offers two
types of data channel cards: the Multi-Rate Transponder and the SFP-to-SFP Media
Module. Configured with CWDM-specific SFP (Small Form Factor Pluggable) optical
transceivers, and connected externally to the Mux/Demux via optical jumper
cables, the channel cards generate and maintain the active data
connections.
Deployed along a WDM trunk at customer service points using
MRV Communications' passive OADM technology, the Multi-Rate Transponder and
SFP-to-SFP Media Module can also be used to create a sophisticated Add/Drop
topology.
The Multi-Rate Transponder performs full clock and data
recovery (3R) per channel at any user selected data rate from 65 Mbps to 2.7
Gbps (65 MHz to 2.7 GHz). By comparison, the SFP-to-SFP Media Module is data
rate transparent and works automatically with any data rate from 100 Mbps to 2.7
Gbps (100 MHz to 2.4 GHz) while performing 2R functions.
Built into every
CWDM Modular system is extensive In-Band and Out-of-Band management
capabilities, including full support of SFP digital diagnostics as per SFF-8472.
Management provides real-time access to information such as transceiver type
(protocol, range, vendor, etc.), operating temperature, TX/RX optical power,
power supply status, and transceiver supply voltage. Management also provides a
means for generating management alerts and warnings when system parameters fall
outside of their normal operating range. |
