Hi From the 3650 data sheet https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-3650-series-switches/datasheet-c78-729449.html     IP unicast routing protocols (static, Routing Information Protocol Version 1 [RIPv1], and RIPv2, RIPng, Enhanced Interior Gateway Routing Protocol [EIGRP] stub) are supported for small-network routing applications with the IP Base feature set. Limited static routing with the LAN Base feature set. Equal-cost routing facilitates Layer 3 load balancing and redundancy across the stack. ●   Advanced IP unicast routing protocols (Open Shortest Path First [OSPF], EIGRP, Border Gateway Protocol Version 4 [BGPv4], and Intermediate System-to-Intermediate System Version 4 [IS-ISv4]) are supported for load balancing and constructing scalable LANs. IPv6 routing (OSPFv3, EIGRPv6) is supported in hardware for maximum performance. OSPF for routed access is included in the IP Base image. The IP Services feature set is required for full OSPF, EIGRP, BGPv4, and IS-ISv4. ●   Policy-based routing (PBR) allows superior control by facilitating flow redirection regardless of the routing protocol configured. Virtual routing and forwarding (VRF)-Lite enables a service provider to support two or more VPNs, with overlapping IP addresses. The IP Base feature set is required. ●   Protocol-independent multicast (PIM) for IP multicast routing is supported, including PIM sparse mode (PIM‑SM), PIM dense mode (PIM-DM), PIM sparse-dense mode, and source-specific multicast (SSM). The IP Services feature set is required. ●   IPv6 addressing is supported on interfaces with appropriate show commands for monitoring and troubleshooting. ... View more

Hi, Here i a link to a nice document that shows pictures and good information. https://www.cisco.com/c/en/us/td/docs/interfaces_modules/transceiver_modules/installation/note/78_15160.html Make sure that along the line of your fibres you are not breaking the length rules in Table 2 ( You will need to find the spec of your patch leads and cable) Also remember that there needs to be a "cross" of the fibres in the length somewhere TRANSMIT -------->>>------------ X -------------->>>----- RECEIVE RECEIVE  --------<<<<----------  X ------------<<<<<<<--- TRANSMIT Look a fig 1 -- It shows which strand is Transmit & Receive   ...
