1270 - 1450nm SFP+ ER Optical Transceiver Modules For Cisco Switches Duplex LC Connector

10Gb/s CWDM 1270~1450nm 40km SFP+ ER Optical Transceiver Module

Description:

E-link’ LNK-10G SFP+ ER Small Form Factor 10Gb/s (SFP+) transceivers are compliant with the current SFP+ Multi-Source Agreement (MSA) Specification. The high performance cooled 1270～1450nm CWDM DFB transmitter and high sensitivity PIN receiver provide superior performance for Ethernet applications up to 40km optical links.

The SFP+ Module compliants with SFF-8431, SFF-8432 and IEEE 802.3ae 10GBASE-ER. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472.

Specification:

• Absolute Maximum Ratings

• Electrical Characteristics (T_OP = 0 to 70 °C, VCC = 3.135 to 3.465 Volts)

Note:

1. Connected directly to TX data input pins. AC coupling from pins into laser driver IC.
2. Per SFF-8431 Rev 3.0
3. Into 100 ohms differential termination.
4. 20%～80%
5. LOS is an open collector output. Should be pulled up with 4.7k – 10kΩ on the host board. Normal operation is logic 0; loss of signal is logic 1. Maximum pull-up voltage is 5.5V.

• Optical Characteristics (TOP = 0 to 70°C, VCC = 3.135 to 3.465 Volts)

Note:

1. Average power figures are informative only, per IEEE802.3ae.
2. TWDP figure requires the host board to be SFF-8431compliant. TWDP is calculated using the Matlab code provided in clause 68.6.6.2 of IEEE802.3ae.
3. 12dB reflection.
4. Conditions of stressed receiver tests per IEEE802.3ae. CSRS testing requires the host board to be SFF-8431 compliant.
5. Receiver overload specified in OMA and under the worst comprehensive stressed condition.
