Chassis family provides 'one box solution' for CWDM services

In addition to the physical conversion of either local fibre or copper to specific CWDM wavelengths, the product also offers advanced management features allowing the operator to monitor a wide variety of parameters, most importantly quality of the optical signal. Fibre installations have not kept pace with the demands made of the physical infrastructure. As an operator/owner of fibre, going back to install new ‘dark’ fibre is cost prohibitive. For a customer, renting extra dark fibre will obviously involve extra costs.

A solution to limited fibre availability is provided by CWDM (Coarse Wavelength-Division Multiplexing) technology, a method by which multiple wavelengths of light are multiplexed into a dedicated fibre pair and demultiplexed at the other end of the link. CWDM links are traditionally point-to-point, all wavelengths are independent of each other and they can carry data from different devices, services or customers. Multiplexing effectively increases the bandwidth of the pre-installed fibre.

CWDM systems offer service providers and Enterprise companies scalable and easy-to-deploy Gigabit Ethernet and Fibre Channel and TDM services for their networks, which may be deployed in data centres, on campus or metropolitan-area access networks. B&B Electronics can provide a cost effective, compact, single chassis CWDM solution. The iMediaChassis chassis and associated modules can offer:

• Copper to CWDM conversion (TDM [E1], 100Mbps, GigE, 10GigE [CX4])
• Optical to CWDM conversion (100Mbps, GigE, 10GigE, FibreChannel, 10Gig FibreChannel, OC-192 / STM-64)

Within one chassis, the CWDM wavelengths can be created and in addition up to 8 CWDM channels can be MUX/DEMUX’d. This solution also has the advantage of being SNMP compliant, the operator can monitor optical information such as receive and transmit strengths.
The B&B Electronics iMediaChassis offers a mix of up to eight conversion modules, E1, GigE and 10GigE. For E1 the interface to the local equipment will be via RJ-48, for GigE the interface could be optical or copper and finally for 10GigE the interface will be optical. In each of the modules the applicable CWDM SFP, SFP+ would be installed.

Typical application for this solution would be multi-service provisioning over a dedicated point to point fibre e.g. ISP/Telco provided optical link, or a rented dark fibre. The iMediaChassis provides 20 slots with dual AC input and two load sharing, hot-swap AC power modules providing N+1 redundant power DC input power supplies are also available. If required an optional SNMP Management Module may also be specified.

CWDM solutions can be provided for:

E1, Ethernet (100Mbps, 1GigE, 10GigE), Fibre Channel (2.4Gig), OC48(2.4Gig), OC192 (10Gig)

Multiplex/de-multiplex solutions:

4 channel or 8 channel + 1x expansion port.
