What is claimed is: 1. An electromagnetic interference (EMI) system for use with an optical transceiver module, the EMI system comprising: an EMI collar configured to be secured to a housing of the optical transceiver module, the EMI collar having an opening formed therein that is configured to allow a latch lock pin of a latching mechanism of the transceiver module to be inserted through and retracted through the opening; and wherein the configuration of the EMI collar includes one or more electrically conductive elements that provide one or more electrically conductive pathways between the module housing and a cage if the EMI collar is secured to the housing and the optical transceiver module is contained within the cage, said one or more electrically conductive elements of the EMI collar include spring fingers that are spaced apart at predetermined fixed spatial intervals about a circumference of the EMI collar, each spring finger having a fold formed therein that biases a tip of the spring finger into electrically conductive contact with the module housing when the EMI collar is secured to the module housing, and wherein if the optical transceiver module has the EMI collar secured thereto and is contained within the cage, each fold is in electrically conductive contact with the cage, said one or more electrically conductive elements of the EMI collar include one or more electrically conductive bumps, and wherein if the EMI collar is secured to the housing of the transceiver module and the optical transceiver module is contained within a cage, said one or more electrically conductive bumps are in contact with a latch of the cage. 2. The EMI system of claim 1, wherein said one or more electrically conductive elements of the EMI collar include one or more electrically conductive fingers that project inwardly toward the module housing when the collar is secured to the housing, and wherein the inwardly projecting fingers are spaced apart at predetermined fixed spatial intervals about a circumference of the EMI collar such that when the collar is secured to the module housing and the module is inserted into a cage, the inwardly projecting fingers provide electrically conductive pathways between the module housing and the cage. 3. The EMI system of claim 1, wherein the collar includes a bent portion that is located adjacent a distal end of a latch base of the latching mechanism when the collar is secured to the module housing, and wherein unlocking of the latching bail mechanism causes the distal end of the latch base to abut an end of the bent portion of the collar, and wherein abutment of the distal end of the latch base with the end of the bent portion of the collar causes the latch base to pivot on the end of the bent portion, and wherein the pivoting of the latch base on the end of the bent portion causes the latch lock pin of the latching bail mechanism to be retracted. 4. A method for providing EMI shielding in an optical transceiver module comprising: providing an EMI collar configured to be secured to a housing of the optical transceiver module, the EMI collar having an opening formed therein that is configured to allow a latch lock pin of a latching mechanism of the transceiver module to be inserted through and retracted through the opening; and securing the EMI collar to the module housing, and wherein the configuration of the EMI collar includes one or more electrically conductive elements that provide one or more electrically conductive pathways between the module housing and a cage when the EMI collar is secured to the housing and the optical transceiver module is contained within the cage, wherein the collar includes a bent portion that is located adjacent a distal end of a latch base of the latching mechanism of the transceiver module, and wherein unlocking of the latching bail mechanism causes the distal end of the latch base to abut an end of the bent portion of the collar, and wherein abutment of the distal end of the latch base with the end of the bent portion of the collar causes the latch base to pivot on the end of the bent portion, and wherein the pivoting of the latch base on the end of the bent portion causes the latch lock pin of the latching bail mechanism to be retracted. 5. The method of claim 4, wherein said one or more electrically conductive elements of the EMI collar include one or more electrically conductive fingers that project inwardly toward the module housing, and wherein the inwardly projecting fingers are spaced apart at predetermined fixed spatial intervals about a circumference of the EMI collar such that if the module is inserted into a cage, the inwardly projecting fingers provide electrically conductive pathways between the module housing and the cage. 6. The method of claim 4, wherein said one or more electrically conductive elements of the EMI collar include spring fingers that are spaced apart at predetermined fixed spatial intervals about a circumference of the EMI collar, each spring finger having a fold formed therein that biases a tip of the spring finger into electrically conductive contact with the module housing, and wherein if the optical transceiver module having the EMI collar secured thereto is contained within a cage, each fold is in electrically conductive contact with the cage. 7. The method of claim 6, wherein said one or more electrically conductive elements of the EMI collar include one or more electrically conductive bumps, and wherein if the optical transceiver module is contained within a cage, said one or more electrically conductive bumps are in contact with a latch of the cage. 8. An electromagnetic interference (EMI) system for use with an optical transceiver module, the EMI system comprising: an EMI collar configured to be secured to a housing of the optical transceiver module, the EMI collar having an opening formed therein that is configured to allow a latch lock pin of a latching mechanism of the transceiver module to be inserted through and retracted through the opening; and wherein the configuration of the EMI collar includes one or more electrically conductive elements that provide one or more electrically conductive pathways between the module housing and a cage if the EMI collar is secured to the housing and the optical transceiver module is contained within the cage, wherein said one or more electrically conductive elements of the EMI collar include one or more electrically conductive bumps, and wherein if the EMI collar is secured to the housing of the transceiver module and the optical transceiver module is contained within a cage, said one or more electrically conductive bumps are in contact with a latch of the cage. 9. The EMI system of claim 8, wherein the EMI collar has four sides that form a continuous circumference. 10. The EMI system of claim 8, wherein said one or more electrically conductive elements of the EMI collar include one or more electrically conductive fingers that project inwardly toward the module housing when the collar is secured to the housing, and wherein the inwardly projecting fingers are spaced apart at predetermined fixed spatial intervals about a circumference of the EMI collar such that when the collar is secured to the module housing and the module is inserted into a cage, the inwardly projecting fingers provide electrically conductive pathways between the module housing and the cage. 11. The EMI system of claim 8, wherein the collar includes a bent portion that is located adjacent a distal end of a latch base of the latching mechanism of the transceiver module, and wherein unlocking of the latching bail mechanism causes the distal end of the latch base to abut an end of the bent portion of the collar, and wherein abutment of the distal end of the latch base with the end of the bent portion of the collar causes the latch base to pivot on the end of the bent portion, and wherein the pivoting of the latch base on the end of the bent portion causes the latch lock pin of the latching bail mechanism to be retracted.
