Q&A

----------------------------------------------------------------------------------------------------

Q: What is the optical and electrical characteristics of SFP transceiver?

 

A: 1. The optical power is launched into SMF.

 

2. PECL input, internally AC-coupled and terminated.

 

3. Measured with a PRBS 223-1 test pattern @155Mbps, BER ≤1×10-10.

 

4. Internally AC-coupled.

 

 

Q: What types of sfp module could you supply?

 

A: We supply many types of SFP transceiver modules, from 155Mbps to 10+Gbps, and 100% Compliant with Cisco, HUAWEI, ALCTEL, H3C and others MSA SFP Specification and SFF-8472/SFF-8472. Our SFP Transceiver Module product like 2G,4G,10G, etc, with good price and excellent quality.
