Plug-In Interfaces Technology
GBIC (Gigabit Interface Converter and SFP (Small Form Pluggable) modules are extremely small, hotswappable
transceiver components that can be plugged into
a variety of networking equipment. MRV produces both fiber optic
and copper SFP modules for a variety of protocols.
MRV supplies standard fiber modules in
addition to optical transceivers at other wavelengths for use in
CWDM (Coarse Wave Division Multiplexing) applications, and a
wide variety of copper for various protocols.
Optical SFPs often include Digital Diagnostics (according to SFF-8472) that
provide a powerful optical management tool.
Plug-In interfaces provide several key benefits:
Cost savings:
- Reduced initial cap-ex due to MRV vertical integration
- Reduced inventory management costs - a small number of parts can be combined to create a wide range of solutions and keeping on-hand spares is much simpler with plug-in interfaces
- Reduced ongoing op-ex due to digital diagnostics preemptive monitoring
Flexibility - Plug-In interfaces provide flexible solutions for:
- Virtually any protocol in existence:
- Ethernet (10, 100, 1000)
- SONET/SDH (OC3/12/48 and STM-1/4/16)
- Fibre Channel (1G, 2G)
- ESCON, FICON
- Digital Video (SDI SMPTE 270Mbps, HDTV)
- Virtually any physical interface in existence:
- Copper (RJ-45, BNC) or Fiber-Optic (DSC/LC)
- Multi-mode or Single-mode
- Single Fiber
- 'Colored' optics for CWDM and DWDM applications
Digital Diagnostics Management:
- Alarm/Warning thresholds allow preemptive solutions before actual problems occur
- Transmit/Receive power monitoring in real-time allows fi ber-optic signal quality measurement
- Temperature/Voltage monitoring in real-time allows advanced environment measurement
- Database of confi guration parameters (vendor, serial number, wavelength, etc.) for simple inventory control
Density -
SFP modules provide high port density, as many as 32 ports in a
1-RU space. Such a density is extremely diffi cult to accomplish
using any other method, and is impossible in any mixed
environment, where ports of different kinds are required in a
high-density system.
