From the image, mentioned in the previous post, here are my observations --

The ADVA logo in the bottom left hand corner discloses it to be a document originating from Adva Optical Networking and is part of a "FSP 150CPMR EAD 10/100/1000 Installation Guide". ["EAD" is an Openreach abbreviation for "Ethernet Access Direct".]

The two ends of the fibre optical link are designated as a "Local A End" and as a "Remote B End".

There are two power variants, either dual AC (mains supply) or dual DC supply, for each end. The relevant "BT Order Codes" are:
  • FBT-ORNT-11-A (Dual AC variant, A End)
  • FBT-ORNT-13-A (Dual DC variant, A End)
  • FBT-ORNT-11-B (Dual AC variant, B End)
  • FBT-ORNT-13-B (Dual DC variant, B End)
The difference between the A and B End devices is that the former just has a male DE-9 serial interface for device management whereas the latter has a male DE-9 serial interface and two 8P8C modular sockets, the former of which appears to be an Ethernet interface and the latter of which appears to be serial console interface, for device management.

[After many months of eBay viewing I have seen that the FBT-ORNT-11-B device is most predominately available (prices ranging from £0-10 to £52-50), with the occasional appearance of the FBT-ORNT-11-A device. No FBT-ORNT-13-{A|B} devices have ever been seen.]

As for the details of the SFP optical transceivers the image is not clear enough to read all the information, verbatim. However possessing a transceiver, as used for the main link at a B End device, and alignment with that which can be read allows me to state that the "BT Order Codes" are:
  • FBT-SFP-01 [Colour coded blue, 10km maximum fibre length, 1310nm Tx, 1550nm Rx, A End main fibre link (or B End backup fibre link, if provided).]
  • FBT-SFP-02 [Colour coded yellow, 10km maximum fibre length, 1550nm Tx, 1310nm Rx, B End main fibre link (or A End backup fibre link, if provided).]
I am just about able to see that the network fibre is singlemode, 9/125um, bi-directional operation. With regards to the optical fibre connectors, we have agreed [in an earlier thread] that they are SC [possibly SC/UPC].

The other information at the right hand side, including the table in the bottom corner, cannot be reliably read.

That's about what I got out of it. No passwords, though...

Interesting choice to reverse optics for the backup link.

Interesting choice to reverse optics for the backup link.

Looking again at my local copy, trimmed and enhanced, of the image I see that the fourth paragraph, on the right hand side, has the heading "Resilient Installations (network ports A and B)". Typing it out, in full, that paragraph reads --

4. Fit the first pair of SFP modules as detailed in steps 1-3 above.
5. For the second pair of optics, fit the longer wavelength SFP module in
local chassis network port B and the shorter wavelength SFP module in
remote chassis network port B.
Note: This will help prevent the network fibres in network ports A and B
being crossed over between the local and remote ends.
6. Connect the BT network fibres directly to the SFP module as shown.


At its first reading, I was puzzled.  ???  I then questioned what I had read.  :-\  Finally I understood.   :)

My first thought on reading it was that it wouldn't work if opposite ends used differing frequencies ... before I realised they just weren't being very clear.

For anyone still confused: when a single fibre is used in bidirectional mode, then an SFP uses two wavelengths, one as transmit, one as receive. At the far end, a different type of SFP is used which transmits & receives the other way around.

The fibre I have played with is the stuff used in LAN switches, so always comes as pairs of unidirectional fibres instead. I sometimes need a kick in the head to remember it can work other ways

With a very sharp blade, the "GUARANTEE VOID IF SEAL BROKEN" label was slit across at the junction of the lid and the base of the casing.

Six torq and ten cross-head screws were then removed and the lid was lifted off.

A small amount of dust was blown out of the fans.

The PCB was scrutinised for anything interesting. An overview photograph was taken, a copy of which is attached, below. (It was impossible to position the camera directly over the mid-point of the unit, so the image is not truly rectilinear. If anyone would be able and willing to manipulate the original image via, say, GIMP (GNU Image Manipulation Program) or similar then please let me know.)

The first item of interest was the button cell, towards the near left-hand corner of the PCB. With aid of a magnifying glass, it was seen to be marked 3V. Usage of a DVM showed it to be supplying a very healthy 3.04V.

From a careful examination, it was seen that the PCB could be populated with various other components and was, thus, a multi-purpose basis for other members of the "FSP 150" family.

A small component was seen towards the rear right-hand corner which looked "interesting".  ;)  It was worth a close-up photograph, also attached below, and one of the DMM probes was used as a pointer to the component. It is a push button . . . and it deserved a push (or two).

The FSP150CP was linked to a computer via a standard null-modem cable, a logging screen session was invoked by a "screen -L -U /dev/ttyS0 57600" command and the the FSP150CP was powered up. The usual boot-up sequence was observed and once the familiar "Login    :" line was seen, the button was pushed. The FSP150CP promptly rebooted. Here is the screenlog of that experiment --

Not particularly interesting.  :(

That screenlog file was split into two and an sdiff was performed upon the two halves --

A difference can now be seen. The boot sequence, as a result of the button push, omits two steps that are performed upon a power-on (cold) boot -- "Configuring FPGA" and "Clearing SDRAM".  :hmm:

FPGA  - Field Programmable Gate Array.
SDRAM - Synchronous Dynamic Random Access Memory.

A second "button push" experiment was then performed. Another logging screen session was invoked. With the FSP150CP un-powered, the button was pressed & held depressed and then the FSP150CP was powered up. After the passage of time taken by a normal, cold, boot the button was released. Examination of the screenlog file showed that the device just cyclically re-booted --

Not very interesting -- or useful.  :(
