The Optical Internetworking Forum (OIF)
has released 4 specifications governing different approaches
to 10 Gbps (OC192) implementation. The purpose of this document
is to provide a short explanation of each approach and the
associated cabling solutions. Optical Connectivity is committed
to the VSR (very short reach) application series and provides
a full-range of interconnect solutions for this emerging technology,
especially in the parallel optics versions of the VSR programs.
- OIF-VSR-01.0 (VSR-1)
| Interface: |
Tx-MTP®
Rx-MTP® |
| Cable / Glass Count: |
Uses 12 fiber - 62.5/125
ribbon each for Tx and Rx Ports |
| Application: |
All 12 fibers of the ribbon
are used, 10 fibers carry data at 1.25 Gbps; fibers
11 and 12 are used for error detection and parity
checks, transmission at 850 nm wavelength, for each
direction |
| Glass Performance: |
62.5/125 glass must meet
IEC 793-2: 1992 Type A1b & the ribbon cable shall
have a maximum differential skew between fibers of
100 ps/m. |
| To order,
request quantity 2 of part number: V23857-C6476-Axxx
when xxx = length in meters. One assembly is needed
for the Transmit side and the second assembly is for
the Receive side. |
- OIF-VSR-02.0 (VSR-2)
| Interface: |
Tx - typically SC
Rx - typically SC |
| Cable / Glass Count: |
Uses 2 fiber zipcord cable
- 9/125 singlemode fiber for Tx and Rx ports |
| Application: |
1 fiber is used to carry
data at 10 Gbps in each direction at the 1310 nm wavelength. |
| Glass Performance: |
industry standard singlemode
glass is used |
| For SC duplex
assemblies, request JZ-010SSxxxP where xxx = length
in meters. |
- OIF-VSR-03.0 (VSR-3)
| Interface: |
Tx / Rx in one MTP® connector |
| Cable / Glass Count: |
Uses 12 fiber ribbon but
only 8 fibers are active - 50/125 glass |
| Application: |
12 fiber ribbon format
used in a single MTP® connector but 4 fibers operating
at 2.5 Gbps operate in each direction (see diagram
below) at the 850 nm wavelength |
| Glass Performance: |
50/125 glass must meet
ANSI TIA/EIA-455-30B |
| To order,
request part number V23857-B6476-Axxx where xxx =
length in meters. |
- OIF-VSR-04.0 (VSR-4)
| Interface: |
a single fiber each for
Tx / Rx - connectors not specified |
| Cable / Glass Count: |
Uses duplex fiber, 50/125
glass |
| Application: |
1 fiber is using to carry
data at 10 Gbps in each direction at the 850 nm wavelength |
| Glass Performance: |
50/125 glass with different
performance levels for different transmission distances |
