Introductions To Transceivers

• When optical transceiver was first expanded,
  establishing the performance of it was outspoken.
  The complete network was authorized and owned by
  a single company, and if the system worked,
  thorough testing of the subcomponents was
  irrelevant. Today, most optical networks use
  components that may come from different
  suppliers. Hence, to examine the adaptability of
  each fiber optic transceiver becomes especially
  significant.

How to test a fiber optic transceiver?

• A fiber optical transceiver consists of a
  receiver and the transmitter. When a transmitter
  connect to a receiver through a fiber but the
  system is not able to achieve desired
  bit-error-ratio (BER), both transmitter and the
  receiver is at fault. A low-quality transmitter
  can recoup by a low-quality receiver. You need to
  check the specifications and it needs to be
  assured that any receiver will interoperate with
  a worst-case transmitter, and any transmitter
  will interoperate with a worst-case receiver and
  provide a signal with to quality.

Specifically determining the worst case is often
a complex task. If a receiver needs a minimum
level of power to manage the system BER target,
then that level will precept the minimum allowed
output power of the transmitter. If the receiver
can permit a reliable level of jitter, this will
be used to define the highest acceptable jitter
from the transmitter.

Transmitter testing

• Transmitter parameters may include wavelength and
  shape of the output waveform. The receiver may
  specify tolerance to jitter and bandwidth.
• There are two steps to examine a transmitter
• 1. The input signal used to test the transmitter
  must be good enough. Measurements of jitter and
  an eye mask test must be performed to confirm the
  quality using electrical measurements. An eye
  mask test is a common method to view the
  transmitter waveform and present a vast quantity
  of information about overall transmitter
  performance.
• 2. The optical output of the transmitter must be
  examined using several optical quality metrics
  such as an OMA (optical modulation amplitude),
  mask test, and Extinction Ratio.

Receiver Testing

• To test a receiver, two steps are followed
• 1. One must ensure that the input signal is of
  good enough quality, testing the receiver
  associated with sending a signal that is of poor
  enough quality. To do this, a stressed eye
  depicting the worst case signal shall be created.
  This is an optical signal, which needs to be
  calibrated using jitter and optical power
  measurements.
• 2. Finally, testing the electrical output of the
  receiver must be achieved. Three basic categories
  of tests must be performed
• A mask test, which ensures a large enough eye
  opening. The mask test is usually conducted by a
  BER (bit error ratio) depth.

• 1.Mask test
• This kind of test ensures a large enough eye
  opening. The mask test is usually conducted by a
  BER (bit error ratio) depth.
• 2. Jitter budget test
• This type of test make sure to tests a number of
  certain types of jitter.
• 3. Jitter tracking and tolerance,
• It examines the efficacy of the internal clock
  recovery circuit to track jitter within its loop
  bandwidth.

About 10GB-SR-SFPP

• 10GB-SR-SFPP is an Enterasys compatible 10GBase
  SFP Optical Transceiver and is factory
  preprogrammed with all the important
  configuration data for seamless network
  integration. Our transceivers operate identically
  to Enterasys original transceivers and are 100
  compatible with other OEM and third party
  transceivers. The 10GB-SR-SFPP is 100 MSA
  (Multi-Source Agreement) obedient.
