This bi-directional small form factor pluggable (SFP) transceiver enables bi-directional communication through a single optical fiber. It complies with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA), and complies with Gigabit Ethernet as specified in IEEE STD 802.3 and Fibre Channel as defined in FC-PI-2 Rev. 10.0. The transceiver is RoHS compliant and lead-free.

Features:

  • Single LC receptacle optical interface
  • Hot pluggable
  • 1310nm FP laser transmitter (T13R15) or 1550nm DFB laser transmitter (T15R13)
  • Up to 20km transmission over 9/125 single mode fiber
  • Metal enclosure for lower EMI
  • Single 3.3V power supply
  • Low power consumption <600mW
  • 0 to 70?C operating temperature range
  • RoHS Compliant

Applications:

  • 1.25Gb/s 1000Base-LX Ethernet
  • Fiber Channel Links
  • SONET/SDH

Ordering Information:

SFP-125-BD-a-b-c

Electrical Characteristics (Top=25?C, Vcc=3.3V)

Notes:
1. Non condensing.
2. AC coupled.
3. Into 100 ohm differential termination.
4. 20 ? 80 %
5. LOS is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.
6. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ and ΔDJ.

Optical Characteristics (Top=25?C, Vcc=3.3V)

Notes:
1. Class 1 Laser Safety.
2. Also specified to meet curves in FC-PI-2 Rev. 10.0 Figure 18, which allow trade-off between wavelength, spectral width and OMA.
3. Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average power.
4. Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E) and FC 1x eye masks when filtered.
5. Measured with DJ-free data input signal .In actual application, output DJ will be the sum of input DJ and ΔDJ.
6. Measured with conformance signals defined in FC-PI-2 Rev. 10.0 specifications. 7. Measured with PRBS 2^7-1 at 10^-12 BER .

General Specifications

Notes:
1. Gigabit Ethernet and 1x Fibre Channel compliant.
2. Tested with a PRBS 2^7-1 data pattern.
3. Dispersion limited per FC-PI-2 Rev. 10
4. Attenuation of 0.55 dB/km is used for the link length calculations. Please refer to the Optical Specifications in Table IV to calculate a more accurate link budget based on specific conditions in your application.
