Product Description

Product Description

SUN-QSFP-SR4 Optical Transceiver

Sun Telecom's SUN-QSFP-SR4 series optical transceiver is a 4-channel, pluggable, parallel, fiber-optic QSFP+ transceiver for 40 Gigabit Ethernet applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnects applications. The optical interface uses a 12 fiber MTP (MPO) connector. It integrates four data lanes in each direction with 40 Gbps bandwidth. Each lane can operate at 10.3125 Gbps up to 100m using OM3 fiber or 150m using OM4 fiber.

Features
      1. 4 independent full-duplex channels
      2. 4 channels 850nm VCSEL array
      3. 4 channels PIN photo detector array
      4. Up to 10.3125Gbps data rate per channel
      5. MPO optical connector
      6. Maximum link length of 100m on OM3 fiber and 150m on OM4 fiber 
      7. Maximum power consumption 1.5W

Notes:

1. Module circuit ground is isolated from module chassis ground within the module.
2. Open collector should be pulled up with 4.7k - 10k ohms on host board to a voltage between 3.15V and 3.6V.

Optical Interface Lanes and Assignment
The optical interface port is a male MPO connector. The four fiber positions on the left as shown in Figure 3, with the key up, are used for the optical transmit signals (Channel 1 through 4). The fiber positions on the right are used for the optical received signals (Channel 4 through 1). The central four fibers are physically present.
